# PDFEdit Class

The PDFEdit class provides text and document editing capabilities for PDFs.

## Syntax

```text
PDFEdit
```

## Remarks

The PDFEdit class can be used to automate search and replace operations, text extraction, content composition, and document merging and splitting.

To begin, provide the input document as a file ([InputFile](#inputfile-property-pdfedit-class)), byte array ([InputData](#inputdata-property-pdfedit-class)), or stream ([SetInputStream](#setinputstream-method-pdfedit-class)) and call [Open](#open-method-pdfedit-class). When finished editing the document, call [Close](#close-method-pdfedit-class) to close it and save the changes to either [OutputFile](#outputfile-property-pdfedit-class), [OutputData](#outputdata-property-pdfedit-class), or the stream set in [SetOutputStream](#setoutputstream-method-pdfedit-class).

### Search, Replace, and Extract Text

 Use the [ReplacePageText](#replacepagetext-method-pdfedit-class) and [ReplaceDocumentText](#replacedocumenttext-method-pdfedit-class) methods to iterate through the page or document content and replace all the text elements that match the specified pattern with the provided text. The class fires the [ReplaceText](#replacetext-event-pdfedit-class) event during this operation, providing the flexibility of skipping certain text blocks or updating the replacement string on the fly. For example:

```csharp
pdfedit.InputFile = "invoice.pdf";
pdfedit.OutputFile = "invoice_filled.pdf";

pdfedit.OnReplaceText += (s, e) =>
{
  if (e.Substitute == "/n software")
  {
    e.Substitute = "my company";
  }
};

pdfedit.Open();
int occurrences = pdfedit.ReplacePageText(0, "SELLER_NAME", "/n software");
pdfedit.Close();
```

 Please see [this article](https://www.nsoftware.com/kb/articles/pdfedit-searching-replacing-text) for more details about searching and replacing text.

Additionally, the [GetPageText](#getpagetext-method-pdfedit-class) and [GetDocumentText](#getdocumenttext-method-pdfedit-class) methods let you extract all the text residing on a specific page or in the entire document.

### Content Composition

With PDFEdit, you can also create documents from scratch or add text or images to existing documents using the editing API. This consists of the following four methods:

- [CreateNew](#createnew-method-pdfedit-class) creates a blank PDF document.
- [AddTextBlock](#addtextblock-method-pdfedit-class) adds a block of text.
- [AddBitmap](#addbitmap-method-pdfedit-class) adds an image (JPEG, BMP, or PNG).
- [AddDrawing](#adddrawing-method-pdfedit-class) adds a vector drawing.

The above methods are complemented by a set of formatting methods that let you choose the parameters of the added text or image (where, what color, how big, or how skewed):

- [SetPosition](#setposition-method-pdfedit-class) sets the page to work with and places the cursor at a specific position on the page.
- [SetFont](#setfont-method-pdfedit-class) sets the font to use, including its size, style, and color.
- [SetAlignment](#setalignment-method-pdfedit-class) sets the block alignment (left/center/right, top/center/bottom).
- [SetTransform](#settransform-method-pdfedit-class) sets the transformation matrix, which alters positioning, scaling, rotation angle, and skew.

### Document Merging and Splitting

 Document-level operations can be performed with the [AppendPage](#appendpage-method-pdfedit-class), [InsertPage](#insertpage-method-pdfedit-class), [RemovePage](#removepage-method-pdfedit-class), and [RemovePages](#removepages-method-pdfedit-class) methods.

To copy pages from one document to another, open each document in an individual PDFEdit object. Then, using [SelectPage](#selectpage-method-pdfedit-class), select the page of document 1 that you want to add to document 2, and assign the [PDFPage](#pdfpage-type) object populated in its [SelectedPage](#selectedpage-property-pdfedit-class) property to the [NewPage](#newpage-property-pdfedit-class) property of the recipient document. Finally, commit the page to the recipient document using [AppendPage](#appendpage-method-pdfedit-class) or [InsertPage](#insertpage-method-pdfedit-class).

```csharp
dest.InputFile = "recipient.pdf";
dest.Open();

src.InputFile = "donor.pdf";
src.Open();

src.SelectPage(0);
dest.NewPage = src.SelectedPage;
dest.AppendPage();

dest.Close();
src.Close();
```

 To split the document in two, use [RemovePages](#removepages-method-pdfedit-class) to remove the respective subsets of pages from the document, then save each remaining part. For example:

```csharp
pdfedit.InputFile = "input_4_pages.pdf";
pdfedit.Open();

// Remove the pages after page 1, and save the first part (pages 0-1)
pdfedit.OutputFile = "input_first.pdf";
pdfedit.RemovePages(2, 2);
pdfedit.Close();

// Remove the pages up to and including page 1, and save the second part (pages 2-3)
pdfedit.OutputFile = "input_second.pdf";
pdfedit.Open();
pdfedit.RemovePages(0, 2);
pdfedit.Close();
```

# Close Method ([PDFEdit](#pdfedit-class) Class)

Closes the opened document.

## Syntax

```text
ANSI (Cross Platform)
int Close();

Unicode (Windows)
INT Close();
```

## Remarks

This method is used to close the previously opened document. It should always be preceded by a call to [Open](#open-method-pdfedit-class).

**Example:**

```csharp
component.InputFile = "input.pdf";
component.Open();
// Some operation
component.Close();
```

 If any changes are made to the document, they are saved automatically to [OutputFile](#outputfile-property-pdfedit-class), [OutputData](#outputdata-property-pdfedit-class), or the stream set in [SetOutputStream](#setoutputstream-method-pdfedit-class) when this method is called. To configure this saving behavior, set [SaveChanges](#SaveChanges).

## Error Handling (C++)

This method returns a result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the *GetLastErrorCode()* method after it returns.)

# Config Method ([PDFEdit](#pdfedit-class) Class)

Sets or retrieves a configuration setting.

## Syntax

```text
ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
```

## Remarks

Config is a generic method available in every class. It is used to set and retrieve [configuration settings](#config-settings-pdfedit-class) for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these *internal properties* is provided through the Config method.

To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a [configuration setting](#config-settings-pdfedit-class), you must call *Config("PROPERTY")*. The value will be returned as a string.

## Error Handling (C++)

This method returns a String value; after it returns, call the *GetLastErrorCode()* method to obtain its result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message.

# Convert Method ([PDFEdit](#pdfedit-class) Class)

Converts the document to a different format.

## Syntax

```text
ANSI (Cross Platform)
int Convert(const char* lpszFormat);

Unicode (Windows)
INT Convert(LPCWSTR lpszFormat);
```

## Remarks

This method is used to convert the document to the format specified by *Format*. Possible values are:

| Format | Description |
| --- | --- |
| CompressedPDF | All data streams included in the document are compressed. |
| UncompressedPDF | All data streams included in the document are decompressed. |

## Error Handling (C++)

This method returns a result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the *GetLastErrorCode()* method after it returns.)

# CreateNew Method ([PDFEdit](#pdfedit-class) Class)

Creates a new PDF document.

## Syntax

```text
ANSI (Cross Platform)
int CreateNew();

Unicode (Windows)

*DocumentProperty* specifies the document property to read. Possible values are:

| Document property | Default value | Description |
| --- | --- | --- |
| Xmp | "" | The XML body of the XMP metadata embedded in the document. |
| Xmp[property] | "" | The value of an XMP metadata property. |
| XmpStream | "" | The hex-encoded content of the XMP metadata stream. |

**Example:**

```csharp
pdfedit.InputFile = "input.pdf";
pdfedit.Open();

string description = pdfedit.GetDocumentProperty("Xmp[dc:description]");
string metadataXml = pdfedit.GetDocumentProperty("Xmp");

// Use language descriptors for multi-language properties
string descriptionEs = pdfedit.GetDocumentProperty("Xmp[dc:description[es]]");

pdfedit.Close();
```

 NOTE: Each document property is only populated once the document has been loaded, which is reported by the [DocumentInfo](#documentinfo-event-pdfedit-class) event.

## Error Handling (C++)

component.InputFile = "input.pdf";
component.Open();
for (int i = 0; i < pageCount; i++) component.GetPageProperty(i, "Height");
component.Close();
```

 The page properties can be used to adjust the position of the signature widget based on the page dimensions. For example:

```csharp
int x = int.Parse(pdfsign.GetPageProperty(0, "Width")) - 100;
int y = int.Parse(pdfsign.GetPageProperty(0, "Height")) - 100;
pdfsign.SetWidgetProperty("OffsetX", x.ToString());
pdfsign.SetWidgetProperty("OffsetY", y.ToString());
```

Unicode (Windows)
INT SetPosition(INT iPageIndex, LPCWSTR lpszX, LPCWSTR lpszY);
```

## Remarks

This method is used to define the [Position](#position-property-pdfedit-class) where new text blocks or images are added. The page is identified by *PageIndex* (zero-based), *X* specifies the horizontal position, and *Y* specifies the vertical position.

*X* and *Y* values that are absolute, relative to the current position, and relative to the page dimensions are all supported.

**Example:**

```csharp
// Sets to exact coordinates.
pdfedit.SetPosition(0, "100", "20");
// Moves 20 points to the right and 20 points down from the current position.
pdfedit.SetPosition(0, "{x}+20", "{y}-20");
// Moves 20 points from the right edge and 120 points from the top edge of the page.
pdfedit.SetPosition(0, "{width}-20", "{height}-120");
```

 NOTE: *PageIndex* set to *-1* specifies the last page of the document.

## Error Handling (C++)

This method returns a result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message.

int SetTransform(const char* lpszTranslationX, const char* lpszTranslationY, const char* lpszScaleX, const char* lpszScaleY, const char* lpszRotation, const char* lpszSkewA, const char* lpszSkewB);

Unicode (Windows)
INT SetTransform(LPCWSTR lpszTranslationX, LPCWSTR lpszTranslationY, LPCWSTR lpszScaleX, LPCWSTR lpszScaleY, LPCWSTR lpszRotation, LPCWSTR lpszSkewA, LPCWSTR lpszSkewB);
```

## Remarks

This method is used to specify the transformation matrix to apply when [AddTextBlock](#addtextblock-method-pdfedit-class) or [AddBitmap](#addbitmap-method-pdfedit-class) is called. The transformation matrix defines how the coordinates and content of the newly added text block or image are mapped onto the page.

*TranslationX* and *TranslationY* specify the horizontal and vertical translation of the object in points.

*ScaleX* and *ScaleY* specify the horizontal and vertical scaling of the object (e.g., use *0.5* to scale an image to half its original size).

*Rotation* specifies the rotation angle of the object in degrees counterclockwise.

*SkewA* and *SkewB* specify the horizontal and vertical skew angles of the object in degrees (e.g., use *30* and *20* respectively to slant the object by 30 degrees horizontally and 20 degrees vertically).

## Error Handling (C++)

This method returns a result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the *GetLastErrorCode()* method after it returns.)

# DocumentInfo Event ([PDFEdit](#pdfedit-class) Class)

Fired when the document has been loaded into memory.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireDocumentInfo(PDFEditDocumentInfoEventParams *e);
typedef struct {  int PageCount;
  int reserved;
} PDFEditDocumentInfoEventParams;

Unicode (Windows)
virtual INT FireDocumentInfo(PDFEditDocumentInfoEventParams *e);
typedef struct {  INT PageCount;
  INT reserved;
} PDFEditDocumentInfoEventParams;
```

## Remarks

This event is fired once per document processing routine to report that the document has been processed and loaded into memory.

The handler for this event is a good place to check the document structure and access document-related information such as page number and document file details.

*PageCount* reports the number of pages in the document.

This event is fired when [Open](#open-method-pdfedit-class) is called, but only after [Password](#password-event-pdfedit-class) or [RecipientInfo](#recipientinfo-event-pdfedit-class) is fired (if applicable) and the document has been decrypted.

# Error Event ([PDFEdit](#pdfedit-class) Class)

Fired when information is available about errors during data delivery.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireError(PDFEditErrorEventParams *e);
typedef struct {  int ErrorCode;  const char *Description;
  int reserved;
} PDFEditErrorEventParams;

Unicode (Windows)
virtual INT FireError(PDFEditErrorEventParams *e);
typedef struct {  INT ErrorCode;  LPCWSTR Description;
  INT reserved;
} PDFEditErrorEventParams;
```

## Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The *ErrorCode* parameter contains an error code, and the *Description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-pdfedit-class) section.

# Log Event ([PDFEdit](#pdfedit-class) Class)

Fired once for each log message.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireLog(PDFEditLogEventParams *e);
typedef struct {  int LogLevel;  const char *Message;  const char *LogType;
  int reserved;
} PDFEditLogEventParams;

Unicode (Windows)
virtual INT FireLog(PDFEditLogEventParams *e);
typedef struct {  INT LogLevel;  LPCWSTR Message;  LPCWSTR LogType;
  INT reserved;
} PDFEditLogEventParams;
```

## Remarks

This event is fired once for each log message generated by the class. The verbosity is controlled by the [LogLevel](#LogLevel) configuration setting.

*LogLevel* indicates the detail level of the message. Possible values are:

|  |  |
| --- | --- |
| 0 (None) | No messages are logged. |
| 1 (Info - default) | Informational events such as the basics of the chain validation procedure are logged. |
| 2 (Verbose) | Detailed data such as HTTP requests are logged. |
| 3 (Debug) | Debug data including the full chain validation procedure are logged. |

*Message* is the log message.

*LogType* identifies the type of log entry. Possible values are:

- CertValidator
- Font
- HTTP
- PDFInvalidSignature
- PDFRevocationInfo
- Timestamp
- TSL

# Password Event ([PDFEdit](#pdfedit-class) Class)

Fired when the class detects that the document is encrypted with a password.

## Syntax

```text
ANSI (Cross Platform)
virtual int FirePassword(PDFEditPasswordEventParams *e);
typedef struct {  int Available;  int Cancel;
  int reserved;
} PDFEditPasswordEventParams;

Unicode (Windows)
virtual INT FirePassword(PDFEditPasswordEventParams *e);
typedef struct {  BOOL Available;  BOOL Cancel;
  INT reserved;
} PDFEditPasswordEventParams;
```

## Remarks

This event is fired during document processing to report that the document is encrypted with a password. It may be used to supply the correct decryption password to [Password](#password-property-pdfedit-class).

*Available* indicates whether the decryption password is already available to the class or still needs to be set. If this parameter is *false*, the correct password must be provided for the decryption attempt to succeed.

*Cancel* determines whether the class will stop firing this event to request a password.

# RecipientInfo Event ([PDFEdit](#pdfedit-class) Class)

Fired for each recipient certificate of the encrypted document.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireRecipientInfo(PDFEditRecipientInfoEventParams *e);
typedef struct {  const char *Issuer;  const char *SerialNumber;  const char *SubjectKeyIdentifier;  int Available;  int Cancel;
  int reserved;
} PDFEditRecipientInfoEventParams;

Unicode (Windows)
virtual INT FireRecipientInfo(PDFEditRecipientInfoEventParams *e);
typedef struct {  LPCWSTR Issuer;  LPCWSTR SerialNumber;  LPCWSTR SubjectKeyIdentifier;  BOOL Available;  BOOL Cancel;
  INT reserved;
} PDFEditRecipientInfoEventParams;
```

## Remarks

This event is fired during document processing for each recipient certificate that the document has been encrypted for (if applicable). It may be used to identify the certificate(s) to load and supply to [DecryptionCert](#decryptioncert-property-pdfedit-class).

*Issuer* specifies the subject of the issuer certificate.

*SerialNumber* specifies the serial number of the encryption certificate.

*SubjectKeyIdentifier* specifies the X.509 subjectKeyIdentifier extension value of the encryption certificate, encoded as a hex string.

*Available* indicates whether the decryption certificate is already available to the class or still needs to be set. If this parameter is *false*, the correct certificate must be provided for the decryption attempt to succeed.

*Cancel* determines whether the class will stop firing this event to request a certificate.

NOTE: The document may be encrypted with more than one certificate (or have "more than one recipient"), in which case each certificate causes its own invocation of this event.

# ReplaceText Event ([PDFEdit](#pdfedit-class) Class)

Fired when a substring in the document is due to be replaced.

## Syntax

```text
ANSI (Cross Platform)
virtual int FireReplaceText(PDFEditReplaceTextEventParams *e);
typedef struct {  int PageIndex;  int EntryIndex;  int Offset;  const char *Pattern;  char *Substitute;  int Skip;
  int reserved;
} PDFEditReplaceTextEventParams;

Unicode (Windows)
virtual INT FireReplaceText(PDFEditReplaceTextEventParams *e);
typedef struct {  INT PageIndex;  INT EntryIndex;  INT Offset;  LPCWSTR Pattern;  LPWSTR Substitute;  BOOL Skip;
  INT reserved;
} PDFEditReplaceTextEventParams;
```

## Remarks

This event is fired from within [ReplaceDocumentText](#replacedocumenttext-method-pdfedit-class) and [ReplacePageText](#replacepagetext-method-pdfedit-class), repeatedly, for each located *Pattern* string. It may be used to track and, if required, alter individual text substitutions.

*PageIndex* contains the page number where the entry is located.

*EntryIndex* contains the index number of the entry related to the other entries.

*Offset* specifies the offset of the substring from the beginning of the page or document.

*Substitute* contains the value that *Pattern* will be replaced with. This value matches the *Value* parameter passed to the respective [ReplaceDocumentText](#replacedocumenttext-method-pdfedit-class) or [ReplacePageText](#replacepagetext-method-pdfedit-class) call. Adjust it from the event handler if required.

*Skip* determines whether the class will skip substituting this entry and proceed to the next one.

[Store](#Certificate_f_Store) is used in conjunction with the [Subject](#Certificate_f_Subject) field to specify client certificates. If [Store](#Certificate_f_Store) has a value, and [Subject](#Certificate_f_Subject) or [Encoded](#Certificate_f_Encoded) is set, a search for a certificate is initiated. Please see the [Subject](#Certificate_f_Subject) field for details.

 Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

|  |  |
| --- | --- |
| MY | A certificate store holding personal certificates with their associated private keys. |
| CA | Certifying authority certificates. |
| ROOT | Root certificates. |

When the certificate store type is *cstPFXFile*, this property must be set to the name of the file. When the type is *cstPFXBlob*, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

 **StorePassword** *char**
*Default Value: ""*

If the type of certificate store requires a password, this field is used to specify the password needed to open the certificate store.

 **StoreType** *int*
*Default Value: 0*

The type of certificate store for this certificate.

 The class supports both public and private keys in a variety of formats. When the *cstAuto* value is used, the class will automatically determine the type. This field can take one of the following values:

```csharp
sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11,
                               @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll",
                               "123456", // PIN
                               "CN=cert_subject");
sftp.SSHUser = "test";
sftp.SSHLogon("myhost", 22);
```

```csharp
certmgr.CertStoreType = CertStoreTypes.cstPKCS11;
certmgr.OnCertList += (s, e) => {
  secKeyBlob = e.CertEncoded;
};
certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll";
certmgr.CertStorePassword = "123456"; // PIN
certmgr.ListStoreCertificates();

sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*");
sftp.SSHUser = "test";
sftp.SSHLogon("myhost", 22);
```

| 23 (cstPKCS11) | The certificate is present on a physical security key accessible via a PKCS#11 interface. To use a security key, create a new [Certificate](#certificate-type) object and pass cstPKCS11 as the [StoreType](#Certificate_f_StoreType), the full path of the PKCS#11 DLL as the [Store](#Certificate_f_Store), and the PIN as the [StorePassword](#Certificate_f_StorePassword). Code Example. SSH Authentication with Security Key (without CertMgr): Alternatively, collect the necessary data using the [CertMgr](CertMgr.md#CertMgr) class by calling the [ListStoreCertificates](CertMgr.md#CertMgr_m_ListStoreCertificates) method after setting the corresponding properties accordingly. The certificate information returned in the [CertList](CertMgr.md#CertMgr_e_CertList) event's CertEncoded parameter may be saved for later use. When using a certificate obtained with this approach, pass the previously saved security key information as the [Store](#Certificate_f_Store) and set [StorePassword](#Certificate_f_StorePassword) to the PIN. Code Example. SSH Authentication with Security Key (with CertMgr): |

- Digital Signature
- Non-Repudiation
- Key Encipherment
- Data Encipherment
- Key Agreement
- Certificate Signing
- CRL Signing
- Encipher Only

If the provider is OpenSSL, the value is a comma-separated list of X.509 certificate extension names.

 **UsageFlags** *int (read-only)*
*Default Value: 0*

The flags that show intended use for the certificate. The value of [UsageFlags](#Certificate_f_UsageFlags) is a combination of the following flags:

 **Subject** *char**
*Default Value: ""*

The subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the field is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=example@email.com". Common fields and their meanings are as follows:

| Field | Meaning |
| --- | --- |
| CN | Common Name. This is commonly a hostname like www.server.com. |

If a field value contains a comma, it must be quoted.

 **Encoded** *char**
*Default Value: ""*

The certificate (PEM/Base64 encoded). This field is used to assign a specific certificate. The [Store](#Certificate_f_Store) and [Subject](#Certificate_f_Subject) fields also may be used to specify a certificate.

When [Encoded](#Certificate_f_Encoded) is set, a search is initiated in the current [Store](#Certificate_f_Store) for the private key of the certificate. If the key is found, [Subject](#Certificate_f_Subject) is updated to reflect the full subject of the selected certificate; otherwise, [Subject](#Certificate_f_Subject) is set to an empty string.

## Constructors

```text
Certificate()
```

 Creates a instance whose properties can be set.

```text
Certificate(const char* lpEncoded, int lenEncoded)
```

 Parses * Encoded * as an X.509 public key.

```text
Certificate(int iStoreType, const char* lpStore, int lenStore, const char* lpszStorePassword, const char* lpszSubject)
```

 * StoreType * identifies the type of certificate store to use. See for descriptions of the different certificate stores. * Store * is a byte array containing the certificate data. * StorePassword * is the password used to protect the store.

 After the store has been successfully opened, the component will attempt to find the certificate identified by * Subject * . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The * Subject * parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

# PDFMedia Type

The media object that is included as part of the PDF document.

## Syntax

 *SecurePDFPDFMedia* (declared in *securepdf.h*)

## Remarks

This type contains information about the media object (such as an image) that is included in the document.

The following fields are available:

- [ContentType](#PDFMedia_f_ContentType)

- [Data](#PDFMedia_f_Data)

- [Height](#PDFMedia_f_Height)

- [Size](#PDFMedia_f_Size)

- [Width](#PDFMedia_f_Width)

## Fields

 **ContentType** *char* (read-only)*
*Default Value: ""*

The content type of the media object.

 **Data** *char**
*Default Value: ""*

The raw data of the media object.

If [OutputStream](#PDFMedia_f_OutputStream) is not set to a valid stream, the class writes to this field when an empty string is passed to SaveMedia.

 **Height** *int (read-only)*
*Default Value: 0*

The height of the media object in pixels (i.e., its vertical resolution).

 **Size** *int64 (read-only)*
*Default Value: 0*

The size of the media in bytes.

 **Width** *int (read-only)*
*Default Value: 0*

The width of the media object in pixels (i.e., its horizontal resolution).

## Constructors

```text
PDFMedia()
```

```text
PDFMedia(const char* lpData, int lenData)
```

# PDFPage Type

A container for PDF page details.

## Syntax

 *SecurePDFPDFPage* (declared in *securepdf.h*)

## Remarks

This type contains general information about a document page, such as its dimensions and rotation.

The following fields are available:

- [Handle](#PDFPage_f_Handle)

- [Height](#PDFPage_f_Height)

- [Rotate](#PDFPage_f_Rotate)

- [Width](#PDFPage_f_Width)

## Fields

 **Handle** *int64*
*Default Value: 0*

A handle, a unique identifier of the underlying property object. Use this field to assign objects of the same type in a quicker manner, without copying them fieldwise.

When a handle of one object is passed to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such an operation.

**Example:**

```php
dest.setNewPageHandle(src.getSelectedPageHandle());
```

 **Height** *char* (read-only)*
*Default Value: "0"*

The height of the page in points.

## Syntax

 *SecurePDFPDFPagePosition* (declared in *securepdf.h*)

## Remarks

This type contains information about the current position on a page.

The following fields are available:

- [PageIndex](#PDFPagePosition_f_PageIndex)

- [X](#PDFPagePosition_f_X)

- [Y](#PDFPagePosition_f_Y)

## Fields

 **PageIndex** *int (read-only)*
*Default Value: 0*

# SecurePDFList Type

## Syntax

 *SecurePDFList<T>* (declared in *securepdf.h*)

## Remarks

 *SecurePDFList* is a generic class that is used to hold a collection of objects of type *T*, where *T* is one of the custom types supported by the PDFEdit class.

```text
int GetCount() {}
```

```text
int SetCount(int count) {}
```

```text
T* Get(int index) {}
```

```text
T* Set(int index, T* value) {}
```

|  |  |
| --- | --- |
| Methods |  |
| GetCount | This method returns the current size of the collection. |
| SetCount | This method sets the size of the collection. This method returns 0 if setting the size was successful; or -1 if the collection is ReadOnly. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection. |
| Get | This method gets the item at the specified position. The index parameter specifies the index of the item in the collection. This method returns NULL if an invalid index is specified. |
| Set | This method sets the item at the specified position. The index parameter specifies the index of the item in the collection that is being set. This method returns -1 if an invalid index is specified. Note: Objects created using the new operator must be freed using the delete operator; they will not be automatically freed by the class. |

# SecurePDFStream Type

## Syntax

 *SecurePDFStream* (declared in *securepdf.h*)

## Remarks

 The PDFEdit class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecurePDFStream interface and pass the PDFEdit class an instance of that concrete class.

 When implementing the SecurePDFStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

```text
bool CanRead() { return true; }
```

```text
bool CanSeek() { return true; }
```

```text
bool CanWrite() { return true; }
```

```text
int64 GetLength() = 0;
```

```text
void Close() {}
```

```text
int Flush() { return 0; }
```

```text
int Read(void* buffer, int count) = 0;
```

```text
int64 Seek(int64 offset, int seekOrigin) = 0;
```

```text
int Write(const void* buffer, int count) = 0;
```

|  |  |
| --- | --- |
| Properties |  |
| CanRead | Whether the stream supports reading. |
| CanSeek | Whether the stream supports seeking. |
| CanWrite | Whether the stream supports writing. |
| Length | Gets the length of the stream, in bytes. |
| Methods |  |
| Close | Closes the stream, releasing all resources currently allocated for it. This method is called automatically when a SecurePDFStream object is deleted. |
| Flush | Forces all data held by the stream's buffers to be written out to storage. Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0. |
| Read | Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read. Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed. |
| Seek | Sets the current position within the stream based on a particular point of origin. Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are: 0: Seek from beginning. 1: Seek from current position. 2: Seek from end. Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported. |
| Write | Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written. Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed. |

# Config Settings ([PDFEdit](#pdfedit-class) Class)

 The class accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these *internal properties* is provided through the [Config](#config-method-pdfedit-class) method.

### PDFEdit Config Settings

**AFRelationship[Key]**: The value of the AFRelationship key for the attachment.This setting specifies the value of the AFRelationship key for the attachment. This key in the file specification dictionary expresses the relationship between the attachment and the document, and it must be set for each attachment added to PDF/A-3 documents. *Key* is either the index of the attachment in the [Attachments](#attachments-property-pdfedit-class) collection or the [Name](#PDFAttachment_f_Name) of the attachment.

**AutoTurnPages**: Whether to change the page automatically upon exceeding the upper or lower page boundary.This setting specifies whether the class turns the page automatically. If set to *true*, the class automatically progresses to the next or previous page upon reaching a page boundary while adding new elements or changing the page position. If set to *false*, any new elements are added to the current page, even if they are outside of the visible page region. The default value is *true*.

**CloseInputStreamAfterProcessing**: Whether to close the input stream after processing.This setting determines whether the input stream specified in [SetInputStream](#setinputstream-method-pdfedit-class) will be closed after processing is complete. The default value is *true*.

**CloseOutputStreamAfterProcessing**: Whether to close the output stream after processing.This setting determines whether the output stream specified in [SetOutputStream](#setoutputstream-method-pdfedit-class) will be closed after processing is complete. The default value is *true*.

**CompressStreams**: Whether to compress stream objects.This setting specifies whether the bytes in the document's stream objects are compressed when the document is saved. The default value is *true*.

**DefaultPageHeight**: The default height for newly added pages.This setting specifies the default height, in points, of pages added using [CreateNew](#createnew-method-pdfedit-class) or [AddNewPage](PDFForm.md#PDFForm_m_AddNewPage). The default value is *0*, meaning the class reuses the height of the previous page when adding a new page. If the new page is the first in the document, the height defaults to the standard *792*.

**DefaultPageWidth**: The default width for newly added pages.This setting specifies the default width, in points, of pages added using [CreateNew](#createnew-method-pdfedit-class) or [AddNewPage](PDFForm.md#PDFForm_m_AddNewPage). The default value is *0*, meaning the class reuses the width of the previous page when adding a new page. If the new page is the first in the document, the width defaults to the standard *612*.

**EnforcePDFA**: Whether to enforce PDF/A compliance.This setting specifies whether the class enforces PDF/A compliance when operating on the document. If set to *true*, [PDFALevel](#PDFALevel) and [PDFAPolicy](#PDFAPolicy) are used to establish the level of PDF/A compliance to apply. The default value is *true*.

**FallbackFont**: The fallback font.This setting specifies the font that the class uses if it cannot find the intended font on the local system. In PDF/A, fonts must be embedded into the document, so this setting can be useful when text must be added but no font is available.

**FontPaths**: The font search paths.This setting specifies a CRLF-separated list of directories where the class searches for additional TrueType font files. It is used when resolving a TrueType font specified in [SetFont](#setfont-method-pdfedit-class) without a full file path.

Each entry is interpreted as a directory path used during font lookup. To use a specific TrueType font file, either specify its filename and include the containing directory in this setting, or specify the full file path in [SetFont](#setfont-method-pdfedit-class).

The default value is the system font search paths. These paths are platform-dependent:

|  |  |
| --- | --- |
| Windows | %windir%\Fonts and %LOCALAPPDATA%\Microsoft\Windows\Fonts |
| macOS and iOS | /System/Library/Fonts/, /Library/Fonts/, and ~/Library/Fonts/ |
| Linux | Directories listed by dir entries in /etc/fonts/fonts.conf and /usr/local/etc/fonts/fonts.conf |
| Android | /system/fonts |

On Windows, the .NET and Java editions obtain these locations through the runtime APIs or the *windir*, *SystemRoot*, and *LOCALAPPDATA* environment variables.

To use custom directories together with the default system locations, include both to prevent the current search path list from being replaced. For example:

```csharp
string fontPaths = component.Config("FontPaths");
fontPaths += @"\r\nC:\Fonts";
component.Config("FontPaths=" + fontPaths);
```

**KeepPositionOnInsert**: Whether to keep the current position after inserting an element.This setting specifies whether the class keeps the current position at the set value after inserting an element. In the default configuration, insertion of a new element, such as a text block, moves the page position marker to the right of the newly inserted element. If set to *true*, the class keeps the position marker at its original location after adding the element. The default value is *false*.

**LoadMedia**: Whether to load images from the document.This setting specifies whether the class loads images from the document. If media does not need to be accessed, it can be set to *false* to speed up document processing. The default value is *true*.

**LogLevel**: The level of detail that is logged.This setting controls the level of detail that is logged through the [Log](#log-event-pdfedit-class) event. Possible values are:

|  |  |
| --- | --- |
| 0 (None) | No messages are logged. |
| 1 (Info - default) | Informational events such as the basics of the chain validation procedure are logged. |
| 2 (Verbose) | Detailed data such as HTTP requests are logged. |
| 3 (Debug) | Debug data including the full chain validation procedure are logged. |

**OwnerPassword**: The owner password to decrypt the document with.This setting is used to provide the document owner password for decryption. Though it may be different from [Password](#password-property-pdfedit-class), most implementations use the same value for both.

**PageCopyByRefElements**: The names of page elements to be copied by reference.This setting specifies a semicolon-separated list of names of page elements that are copied by reference (shallow copy) instead of by value when [AppendPage](#appendpage-method-pdfedit-class) or [InsertPage](#insertpage-method-pdfedit-class) is called. If set to an empty string, the class copies all page elements by value, which may lead to inefficient duplication of inherently shared objects such as fonts or bitmaps. The default value is *Resources*.

**PDFALevel**: The PDF/A conformance level to enforce.This setting specifies the desired PDF/A conformance level that the class attempts to enforce when [EnforcePDFA](#EnforcePDFA) is set to *true*. Possible values are:

|  |  |
| --- | --- |
| 1 | PDF/A-1 |
| 2 | PDF/A-2 |
| 3 (default) | PDF/A-3 |

**PDFAPolicy**: The PDF/A policy to follow.This setting specifies the PDF/A policy the class follows when [EnforcePDFA](#EnforcePDFA) is set to *true*. Possible values are:

|  |  |
| --- | --- |
| Default | Maps to Preserve. |
| Preserve | Keep existing document features and only write PDF/A-compliant pieces. If the class needs to write a non-compliant piece, it throws an exception. |
| Enforce | Preserve PDF/A-compliant pieces and attempt to fix violations in the original document. |

**RightPadding**: The width of the whitespace gap to the right of newly added elements.This setting specifies the width, in points, of the empty space that is allowed to the right of newly added elements. Using a non-zero value for this setting allows multiple text blocks and other elements to be placed next to each other without sticking them together. This setting is ignored if [KeepPositionOnInsert](#KeepPositionOnInsert) is set to *true*. The default value is *5*.

**SaveChanges**: Whether to save changes made to the document.This setting specifies whether and how changes made to the PDF document are saved when [Close](#close-method-pdfedit-class) is called. Possible values are:

|  |  |
| --- | --- |
| 0 | Discard all changes. |
| 1 | Save the document to [OutputFile](#outputfile-property-pdfedit-class), [OutputData](#outputdata-property-pdfedit-class), or the stream set in [SetOutputStream](#setoutputstream-method-pdfedit-class), even if it has not been modified. |
| 2 (default) | Save the document to [OutputFile](#outputfile-property-pdfedit-class), [OutputData](#outputdata-property-pdfedit-class), or the stream set in [SetOutputStream](#setoutputstream-method-pdfedit-class), but only if it has been modified. |

**SystemFontNames**: The system font names.This setting returns a CRLF-separated list of system TrueType font names that are supported by the class. This setting is read-only.

**TempPath**: The location where temporary files are stored.This setting specifies an absolute path to the location on disk where temporary files are stored. It can be useful to reduce memory usage.

### Base Config Settings

**BuildInfo**: Information about the product's build.When queried, this setting will return a string containing information about the product's build.

**CodePage**: The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).

**LicenseInfo**: Information about the current license.When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

- Product: The product the license is for.
- Product Key: The key the license was generated from.
- License Source: Where the license was found (e.g., RuntimeLicense, License File).
- License Type: The type of license installed (e.g., Royalty Free, Single Server).
- Last Valid Build: The last valid build number for which the license will work.

**MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*.

**ProcessIdleEvents**: Whether the class uses its internal event loop to process events when the main thread is idle.If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

**SelectWaitMillis**: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

**UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to *true* tells the class to use the internal implementation instead of using the system security libraries.

 On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default.

 To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section.

# Trappable Errors ([PDFEdit](#pdfedit-class) Class)

## Error Handling (C++)

Call the *GetLastErrorCode()* method to obtain the last called method's result code; *0* indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the *GetLastError()* method can be called to retrieve the associated error message.
