Detailed Description

An interface for SignDoc documents.

An object of this class represents one document.

Use SignDocDocumentLoader.loadFromMemory(), SignDocDocumentLoader.loadFromFile(), SignDocDocumentLoader.createPDF(), or SignDocDocumentLoader.createPDFA() to create objects.

If the document is loaded from a file, the file may remain in use until this object is destroyed or the document is saved to a different file with saveToFile(). Please do not change the file while there is a SignDocDocument object for it.

Use getErrorMessage() to get more information after a function call failed.

Member Function Documentation

void addAnnotation	(	int	aPage,
		SignDocAnnotation	aAnnot
	)

Add an annotation to a page.

See SignDocAnnotation for details.

Parameters

[in]	aPage	The page number (1 for the first page).
[in]	aAnnot	The new annotation.

See also: createLineAnnotation(), createScribbleAnnotation(), createFreeTextAnnotation(), DocumentFlags.FailForBrokenTargetStructure

void addAttachmentBlob	(	string	aName,
		string	aDescription,
		string	aType,
		string	aModificationTime,
		byte[]	aData,
		AddAttachmentFlags	aFlags
	)

Add an attachment to the document.

Attachments are supported for PDF documents only.

Parameters

[in]	aName	The name of the attachment. Will also be used as filename of the attachment and must not contain slashes, backslashes, and colons.
[in]	aDescription	The description of the attachment (can be empty).
[in]	aType	The MIME type of the attachment (can be empty except for PDF/A-3 documents).
[in]	aModificationTime	The time and date of the last modification of the file being attached to the document (can be empty). Must be in ISO 8601 extended calendar date format with optional timezone.
[in]	aData	The attachment.
[in]	aFlags	Must be AddAttachmentFlags.Zero.

void addAttachmentFile	(	string	aName,
		string	aDescription,
		string	aType,
		string	aPath,
		AddAttachmentFlags	aFlags
	)

Add an attachment (read from a file) to the document.

Attachments are supported for PDF documents only.

Parameters

[in]	aName	The name of the attachment. Will also be used as filename of the attachment and must not contain slashes, backslashes, and colons.
[in]	aDescription	The description of the attachment (can be empty).
[in]	aType	The MIME type of the attachment (can be empty except for PDF/A-3 documents).
[in]	aPath	The pathname of the file to be attached.
[in]	aFlags	Must be AddAttachmentFlags.Zero.

void addField	(	SignDocField	aField,
		SetFieldFlags	aFlags
	)

Add a field.

See the members of SignDocField for details.

This function can add check boxes, radio button groups, text fields, and signature fields to PDF documents.

When adding a radio button group or a check box field, a value must be set, see SignDocField.setValue() and SignDocField.setValueIndex().

The FieldFlags.NoToggleToOff flag should be set for all radio button groups. Adobe products seem to ignore this flag being not set.

When adding a text field, the justification must be set with SignDocField.setJustification().

Currently, you don't have control over the appearance of the field being inserted except for the text field attributes.

Adding a field to a PDF document that doesn't contain any fields will set the document's default text field attributes to font Helvetica, font size 0, text color black.

Only signature fields can be added to PDF documents having signed signature fields.

TIFF documents support signature fields only and all signature fields must be inserted before the first signature is added to the document (you may want to use invisible fields) unless all existing signature fields have flag FieldFlags.EnableAddAfterSigning set.

Parameters

[in,out]	aField	The new field. The font resource name of the default text field attributes may be modified. The value index and the value may be modified for radio button fields and check box fields.
[in]	aFlags	Set of flags (of enum SetFieldFlags, combined with `\|') modifying the behavior of this function. Pass 0 for no flags.

void addImageFromFile	(	int	aTargetPage,
		string	aPath,
		double	aZoom,
		double	aX,
		double	aY,
		double	aWidth,
		double	aHeight,
		ImportImageFlags	aFlags
	)

Add an image (from a file) to a page.

This function behaves like addImageFromFile2() with an empty string for aDescription, that is, if the document uses Tagged PDF, a dummy alternate description for the image ("image" with language code "en") will provided to avoid breaking standard compliance. It is strongly recommended to use addImageFromFile2() with a meaningful description of the image.

This function uses document (page) coordinates, see Coordinate Systems.

Parameters

[in]	aTargetPage	The 1-based number of the page.
[in]	aPath	The pathname of the file containing the image. Supported formats for inserting into PDF documents are: JPEG, PNG, GIF, TIFF, and BMP.
[in]	aZoom	Zoom factor or zero. If this argument is non-zero, aWidth and aHeight must be zero. The size of the page is computed from the image size and resolution, multiplied by aZoom.
[in]	aX	The X coordinate of the point at which the lower left corner of the image shall be placed.
[in]	aY	The Y coordinate of the point at which the lower left corner of the image shall be placed.
[in]	aWidth	Image width (document coordinates) or zero. The image will be scaled to this width. If this argument is non-zero, aZoom must be zero and either aHeight must be non-zero or ImportImageFlags.KeepAspectRatio must be set in aFlags.
[in]	aHeight	Page height (document coordinates) or zero. The image will be scaled to this height. If this argument is non-zero, aZoom must be zero and either aWidth must be non-zero or ImportImageFlags.KeepAspectRatio must be set in aFlags.
[in]	aFlags	Flags modifying the behavior of this function, See enum ImportImageFlags. ImportImageFlags.KeepAspectRatio is not needed if aZoom is non-zero.

		ImportImageFlags	aFlags,
		string	aDescription,
		string	aLang
	)

Add an image (from a file) to a page (with alternate description).

This function uses document (page) coordinates, see Coordinate Systems.

Parameters

[in]	aTargetPage	The 1-based number of the page.
[in]	aPath	The pathname of the file containing the image. Supported formats for inserting into PDF documents are: JPEG, PNG, GIF, TIFF, and BMP.
[in]	aZoom	Zoom factor or zero. If this argument is non-zero, aWidth and aHeight must be zero. The size of the page is computed from the image size and resolution, multiplied by aZoom.
[in]	aX	The X coordinate of the point at which the lower left corner of the image shall be placed.
[in]	aY	The Y coordinate of the point at which the lower left corner of the image shall be placed.
[in]	aWidth	Image width (document coordinates) or zero. The image will be scaled to this width. If this argument is non-zero, aZoom must be zero and either aHeight must be non-zero or ImportImageFlags.KeepAspectRatio must be set in aFlags.
[in]	aHeight	Page height (document coordinates) or zero. The image will be scaled to this height. If this argument is non-zero, aZoom must be zero and either aWidth must be non-zero or ImportImageFlags.KeepAspectRatio must be set in aFlags.
[in]	aFlags	Flags modifying the behavior of this function, See enum ImportImageFlags. ImportImageFlags.KeepAspectRatio is not needed if aZoom is non-zero.
[in]	aDescription	Alternate description for the image. If this value is an empty string, aLang will be ignored. If this value is an empty string and the document uses Tagged PDF, "image" with language code "en" will be used to avoid breaking standard compliance. It is strongly recommended to use a meaningful description. Escape sequences must not be used.
[in]	aLang	Language identifier for aDescription. Unless aDescription is an empty string, this must be a string containing an RFC 3066 language tag. Example: "en-US".

void addPage	(	int	aTargetPage,
		double	aWidth,
		double	aHeight
	)

Add an empty page to the document.

This function is currently implemented for PDF documents only.

Parameters

[in]	aTargetPage	The 1-based number of the page before which to insert the new page. The page will be appended if this value is 0.
[in]	aWidth	The width of the page (in 1/72 inches for PDF documents).
[in]	aHeight	The height of the page (in 1/72 inches for PDF documents).

void addSignature	(	SignDocSignatureParameters	aSignatureParameters,
		SignDocVerificationParameters	aVerificationParameters
	)

Sign the document.

This function stores changed properties in the document before signing. If string parameter "OutputPath" is set, the signed document will be stored in a new file specified by that parameter and the original file won't be modified. If "OutputPath" is not set, the document will be written to the file from which it was loaded or to which it was most recently saved.

If a PDF document is backed by memory (most recently loaded from memory or saved to a stream) and "OutputPath" is empty, the signed document will not be saved. Use

doc.copyToStream (stream, CopyToStreamFlags.Zero);

or

byte[] blob = doc.copyToMemory (CopyToStreamFlags.Zero);

to save the signed document in that case.

If string parameter "OutputPath" is set to the special value "<memory>" for a PDF document, it will be saved to memory and signed in memory. You'll have to save the document as described in the preceding paragraph.

Some document types may allow adding signatures only if all signatures of the documents are valid.

For PDF documents, this function either signs or certifies the document, see integer parameter DocMDP.

If you are using RFC 3161 timestamps and get SignDocUnexpectedErrorException with a message like "Contents overflow: xxx vs. yyy", try using a bigger value for integer parameter "TimeStampSize".

This function performs a basic verification of the signature after signing a PDF document unless ShootInFootFlags.DontVerifyAfterSigning is set. This ensures that the private key matches the certificate. If that verification fails, SignDocInvalidSignatureException will be thrown.

Parameters

[in]	aSignatureParameters	The signing parameters. The parameters can be used only once, for a single signature.
[in]	aVerificationParameters	Verification parameters or null for default parameters. If revocation checking is enabled in aVerificationParameters, the revocation state of the certificates (subject to integer parameter "VerificationModel") in both the signing certificate's certificate chain and (if RFC 3161 time stamps are enabled) the RFC 3161 time stamp's certificate chain is checked. These verification parameters are not used for verifying the certificate chain of HTTPS connections to RFC 3161 time-stamp servers.

		double	aOpacity,
		AddTextFlags	aFlags,
		string	aLang
	)

Add text to a page (with language identifier).

Multiple lines are not supported, the text must not contain CR and LF characters.

Note: addTextRect2() is better than addText2() for RTL text.

If a PDF/UA document does not specify a natural language, a language identifier is required. If a language identifier is required and aLang is an empty string, the behavior depends on flag DocumentFlags.RequireLang: if DocumentFlags.RequireLang is set, this function will fail if DocumentFlags.RequireLang is not set, language tag "en" (or the language set with setDefaultDocumentLanguage()) will be used.

Changes made to the in-memory copy of the document since it was loaded or saved will not be reflected in the copy written to the blob.

If aIncludeUnsavedChanges is true, unsaved changes made to the in-memory copy of the document will be included (as incremental update for PDF documents) in the blob.

This function does not have side effects on the in-memory copy of the document, that is, unsaved changes remain unsaved (except for being saved to the blob if CopyToStreamFlags.Unsaved is set in aFlags).

Parameters

[in] aFlags Flags modifying the behavior of this function, see enum CopyToStreamFlags.

Returns: A blob containing the copied document.

Flattening an annotation of a PDF document makes its appearance part of the page and removes the selected annotation or all annotations. This function selects all non-widget annotations on the specified pages, ie, it does not flatten fields.

Flattening annotations breaks existing signatures. If you are flattening annotations only for printing with PDF components that don't support annotations, make a copy of the document, pass

SignDocDocument.ShootInFootFlags.AllowBreakingPermissions | SignDocDocument.ShootInFootFlags.AllowBreakingSignatures

to setShootInFoot(), flatten the annotations, print the document, and throw it away.

Parameters

[in]	aFirstPage	1-based number of first page.
[in]	aLastPage	1-based number of last page or 0 to process all pages to the end of the document.
[in]	aFlags	Flags modifying the behavior of this function, see FlattenAnnotationsFlags.

See also: flattenFields(), removeAnnotation()

void flattenField	(	string	aName,
		int	aWidget
	)

Flatten a field.

Flattening a field of a PDF document makes its appearance part of the page and removes the selected widget or all widgets; the field will be removed when all its widgets have been flattened.

Flattening uint signature fields does not work correctly.

Flattening fields breaks existing signatures. If you are flattening fields only for printing with PDF components that don't support annotations, make a copy of the document, pass

SignDocDocument.ShootInFootFlags.AllowBreakingPermissions | SignDocDocument.ShootInFootFlags.AllowBreakingSignatures

to setShootInFoot(), flatten the fields, print the document, and throw it away.

Parameters

[in]	aName	The fully-qualified name of the field.

SignDocProperty [] getProperties ( string aCollection )

Get the names and types of all SignDoc properties of a certain collection of properties of the document.

Use getBooleanProperty(), getIntegerProperty(), or getStringProperty() to get the values of the properties.

There are two collections of SignDoc document properties:

"encrypted" Encrypted properties. Names and values are symmetrically encrypted.
"public" Public properties. Document viewer applications may be able to display or let the user modify these properties.
"pdfa" PDF/A properties (PDF documents only):
- part (PDF/A version identifier: 1, 2, or 3)
- amd (optional PDF/A amendment identifier)
- conformance (PDF/A conformance level: A, B, or U)
All properties in this collection have string values, the property names are case-sensitive. If the "part" property is present, the document claims to be conforming to PDF/A. Your application may change its behavior when dealing with PDF/A documents. For instance, it might want to avoid transparency.
"pdfua" PDF/UA properties (PDF documents only):
- part (PDF/UA version identifier: 1)
- amd (optional PDF/UA amendment identifier)
- corr (optional PDF/UA corrigenda identifier)
All properties in this collection have string values, the property names are case-sensitive. If the "part" property is present, the document claims to be conforming to PDF/UA. Your application may change its behavior when dealing with PDF/UA documents.

Using the same property name in the "encrypted" and "public" collections is not possible. Attempts to get, set, or remove a property in the wrong collection will fail with exception SignDocWrongCollectionException. To move a property from one collection to another collection, first remove it from the source collection, then add it to the target collection.

The "pdfa" and "pdfua" collections are read-only and a property name existing in those collections does not prevent that property name from appearing in one of the other collections.

The syntax of property names depends on the document type and the collection containing the property.

"public" properties of PDF documents are stored according to XMP in namespace "http://www.softpro.de/pdfa/signdoc/public/", therefore property names must be valid unqualified XML names, see the syntax of "Name" in the XML 1.1 specification at http://www.w3.org/TR/2004/REC-xml11-20040204/#sec-common-syn (section 2.3 Common Syntactic Constructs).

For "encrypted" properties and any properties in TIFF documents, property names can contain arbitrary Unicode characters except for NUL.

Parameters

[in] aCollection The name of the collection, see above.

Returns: The properties.

Note: The WinRT component returns null instead of an empty array.

SignDocRenderOutput getRenderedSize ( SignDocRenderParameters aParams )

Get the size of the rendered page in pixels (without actually rendering it).

The returned values may be approximations for some document formats. If multiple pages are selected (integer parameters "FirstPage" and "LastPage" of aParams), the maximum width and maximum height of all selected pages will be used.

Parameters

[in] aParams Parameters such as the page number.

Returns: The width and height of the image that would be computed by renderPageAsImage() and renderPageAsSignDocImage() with aClipRect being null.

See also: renderPageAsImage(), renderPageAsSignDocImage()

SaveFlags getRequiredSaveToFileFlags ( )

Get all flags currently required for saveToFile().

This function currently returns SaveFlags.Incremental (saving the document non-incrementally would destroy existing signatures) or 0 (the document may be saved non-incrementally).

Returns: The flags.

See also: getSaveToFileFlags(), getSaveToStreamFlags(), saveToFile()

double getResolutionX ( int aPage )

Different pages of the document may have different resolutions. Use getConversionFactorX() to get the factor for converting document coordinates to real world coordinates.

See Coordinate Systems.

Parameters

[in] aPage The page number (1 for the first page).

Returns: The horizontal resolution in DPI. The value will be 0.0 if the resolution is not available.

See also: getConversionFactorX(), getResolutionY()

Note that SaveFlags.Incremental cannot be used together with SaveFlags.Linearized even if all these flags are returned by this function. SaveFlags.PDFAButtons is returned only if the document claims PDF/A-1 conformance.

Returns: The flags.

See also: getRequiredSaveToFileFlags(), getSaveToStreamFlags(), saveToFile()

SaveFlags getSaveToStreamFlags ( )

Get all flags currently valid for saveToStream() and saveToMemory().

Returns: The flags.

See also: getSaveToFileFlags(), saveToMemory(), saveToStream()

ShootInFootFlags getShootInFoot ( )

Get the flags set by setShootInFoot().

Returns: The flags currently in force.

See also: setShootInFoot()

SignDocSignature getSignature ( int aIndex )

		byte[]	aData,
		double	aZoom,
		double	aWidth,
		double	aHeight,
		ImportImageFlags	aFlags
	)

Import a page from a blob containing an image.

This function behaves like importPageFromImageBlob2() with an empty string for aDescription, that is, if the document uses Tagged PDF, a dummy alternate description for the image ("image" with language code "en") will provided to avoid breaking standard compliance. It is strongly recommended to use importPageFromImageBlob2() with a meaningful description of the image.

This function is currently implemented for PDF documents only.

Parameters

[in]	aTargetPage	The 1-based number of the page before which to insert the new page. The page will be appended if this value is 0.
[in]	aData	The blob containing the image. Supported formats for inserting into PDF documents are: JPEG, PNG, GIF, TIFF, and BMP.
[in]	aZoom	Zoom factor or zero. If this argument is non-zero, aWidth and aHeight must be zero. The size of the page is computed from the image size and resolution, multiplied by aZoom.
[in]	aWidth	Page width (document coordinates) or zero. If this argument is non-zero, aHeight must also be non-zero and aZoom must be zero. The image will be scaled to this width.

See also: isTaggedPDF()

void removePages	(	ConstArray(int)	aPages,
		KeepOrRemove	aMode
	)

Remove pages from the document.

A document must have at least page. This function will fail if you attempt to remove all pages.

Fields will be removed if all their widgets are on removed pages.

Only signatures in signature fields having the FieldFlags.SinglePage flag set can survive removal of pages.

Parameters

[in]	aPages	An array of one-based page numbers. The order does not matter, neither does the number of occurences of a page number.
[in]	aMode	Tell this function whether to keep or to remove the pages specified by aPages.

void removePDFA ( RemoveFlags aFlags )

Remove PDF/A conformance.

Some operations on PDF documents (such as using standard fonts) are not allowed in PDF/A documents. This function turns a PDF/A document into a plain document, enabling those operations.

This function is available for PDF documents only.

Parameters

[in] aFlags Must be RemoveFlags.Zero.

See also: removePDFUA(), removePermissions()

void removePDFUA ( RemoveFlags aFlags )

Remove PDF/UA conformance.

Some operations on PDF documents (such as using standard fonts) are not allowed in PDF/UA documents. This function turns a PDF/UA document into a plain document, enabling those operations.

This function is available for PDF documents only.

Parameters

[in] aFlags Must be RemoveFlags.Zero.

See also: removePDFA(), removePermissions()

void removePermissions ( RemoveFlags aFlags )

Remove signatures that grant permissions.

If you want to modify (beyond adding signature fields, signing signature fields, and filling in form fields) a PDF document that has permissions granted to Adobe Reader by digital signatures, you have to remove those signatures first by calling this function. That action will remove the permissions for Adobe Reader but enable modifying the document without breaking those signatures.

Permissions granted via encryption are not altered by this function.

This function is available for PDF documents only.

Parameters

[in] aFlags Must be RemoveFlags.Zero.

See also: removePDFA(), removePDFUA(), setShootInFoot()

void removeProperty	(	string	aCollection,
		string	aName
	)

Remove a SignDoc property.

In the "public" and "encrypted" collections, property names are compared under Unicode simple case folding, that is, lower case and upper case is not distinguished.

Parameters

[in]	aCollection	The name of the collection, see getProperties().
[in]	aName	The name of the property.

See also: getProperties(), setStringProperty()

void removeXFA ( RemoveFlags aFlags )

Remove XFA (XML Forms Architecture) content.

SignDoc SDK does not support XFA (XML Forms Architecture) and therefore addSignature(), addField(), applyFdf(), and setField() remove XFA from the document to avoid descrepancies between "classic" form fields and XFA. This function is available for PDF documents only.

You can also remove XFA content by calling this function. It will fail if the document prohibits removal of XFA (removing XFA from signed documents breaks signatures).

This function is available for PDF documents only.

Parameters

[in] aFlags Must be RemoveFlags.Zero.

byte [] renderPageAsImage	(	SignDocRenderOutput	aOutput,
		SignDocRenderParameters	aRenderParameters,
		SignDocVerificationParameters	aVerificationParameters,

Returns: The SignDocImage object containing the rendered page.

See also: computeZoom(), getRenderedSize()

void saveToFile	(	string	aPath,
		SaveFlags	aFlags
	)

Save the document to a file.

After a successful call to this function, the document behaves as if it had been loaded from the specified file.

Saving a signed PDF document without SaveFlags.Incremental will fail unless SaveFlags.AutoIncremental is also set. See also getRequiredSaveToFileFlags().

The file will remain open until the document is saved again or the SignDocDocument object is closed or destroyed.

Parameters

[in]	aPath	The pathname of the file to be created or overwritten. Pass an empty string to save to the file from which the document was loaded or most recently saved (which will fail if the documment was loaded from memory or saved to a stream). See Using SignDoc SDK in Windows Store apps for restrictions on pathnames in Windows Store apps.
[in]	aFlags	Set of flags (of enum SaveFlags, combined with `\|') modifying the behavior of this function. Pass 0 for no flags. Which flags are available depends on the document type. Which flags are required depends on the document state. Call getRequiredSaveToFileFlags() to get the flags that are required.

See also: copyToMemory(), copyToStream(), getRequiredSaveToFileFlags(), getSaveToFileFlags(), saveToMemory(), saveToStream(), SignDocDocumentLoader.loadFromFile(), SignDocDocumentLoader.loadFromMemory()

byte [] saveToMemory ( SaveFlags aFlags )

Save the document to a blob.

This function may have side effects on the document such as marking it as not modified which may render SaveFlags.Incremental useless for the next saveToFile() call unless the document is changed between those two calls.

After calling this function, the document will be backed by memory.

Parameters

[in] aFlags Set of flags (of enum SaveFlags, combined with `|') modifying the behavior of this function. Pass 0 for no flags. Which flags are available depends on the document type.

Returns: A blob containing the saved document.

This function may have side effects on the document such as marking it as not modified which may render SaveFlags.Incremental useless for the next saveToFile() call unless the document is changed between those two calls.

After calling this function, the document will be backed by memory.

Parameters

[in]	aStream	The document will be saved to this stream.
[in]	aFlags	Set of flags (of enum SaveFlags, combined with `\|') modifying the behavior of this function. Pass 0 for no flags. Which flags are available depends on the document type.

It's not possible to change the type of a property.

Parameters

[in]	aCollection	The name of the collection, see getProperties().
[in]	aName	The name of the property.
[in]	aValue	The new value of the property.

See also: getProperties(), removeProperty(), setIntegerProperty(), setStringProperty(), addSignature()

		int	aMinor
	)

Request to not make changes to the document which are incompatible with an older version of this class.

No features introduced after aMajor.aMinor will be used.

Passing a version number before 1.11 or after the current version will fail.

Parameters

[in]	aMajor	Major version number.
[in]	aMinor	Minor version number.

void setCompressionLevel ( int aLevel )

Set the FlateDecode compression level.

Calling this function has an effect for PDF documents only. You might want to use a low compression level on slow machines such as mobile devices. That will speed up operations such as embedding fonts, adding attachments, and adding images.

Parameters

[in] aLevel The new compression level for encoding data with the FlateDecode filter. Allowed values are 0 (fastest, do not use FlateDecode), and 1 (fast, least compression) through 9 (slowest, best compression). The default value is 6.

void setDefaultDocumentLanguage ( string aLang )

Set the language identifier to be used if a language identifier is required but the document doesn't provide one.

If this function is not called, "en" will be used.

This function is available for PDF documents only.

Parameters

[in] aLang An RFC 3066 language tag. Must not be an empty string. Example: "en-US".

See also: getDocumentLanguage(), setDocumentLanguage(), DocumentFlags.RequireAlternateFieldName, DocumentFlags.RequireLang

void setDocumentLanguage ( string aLang )

Set the document's natural language.

That language applies to all text unless overridden locally.

This function is available for PDF documents only.

Parameters

[in] aLang The natural language for the document (an RFC 3066 language tag). Must not be an empty string. Example: "en-US".

See also: getDocumentLanguage(), setDefaultDocumentLanguage(), DocumentFlags.RequireAlternateFieldName, DocumentFlags.RequireLang

void setField	(	SignDocField	aField,
		SetFieldFlags	aFlags
	)

Change a field.

This function changes a field in the document using attributes from a SignDocField object. Everything except for the name and the type of the field can be changed. See the member functions of SignDocField for details.

Always get a SignDocField object for a field by calling getField(), getFields(), or getFields(), then apply your modifications to that object, then call setField().

Applications should not call setField() for fields that are locked, ie, have FieldFlags.ReadOnly set in the return value of SignDocField.getFlags(). However, setField() does not fail in that case.

The coordinates of the field are not changed unless SetFieldFlags.Move is set in aFlags.

Do not try to build a SignDocField object from scratch for changing a field as future versions of the SignDocField class may have additional attributes.

This function is implemented for PDF documents only.

This function always fails for PDF documents that have signed signature fields.

Parameters

[in,out]	aField	The field to be changed. The font resource name of the default text field attributes may be modified. The value index and the value may be modified for radio button fields and check box fields.
[in]	aFlags	Set of flags (of enum SetFieldFlags, combined with `\|') modifying the behavior of this function. Pass 0 for no flags.

See also: addField(), getFields(), removeField(), DocumentFlags.FailForBrokenTargetStructure, DocumentFlags.RequireAlternateFieldName

This function fails for signed PDF document.

This function always fails for TIFF documents.

Parameters

[in,out] aData The new default text field attributes. The font resource name will be updated.

See also: addField(), getTextFieldAttributes(), SignDocField.setTextFieldAttributes()

static string [] splitEscapeSequences ( string aInput )

static

Split a string obtained from a PDF text string into escape sequences and text segments.

You don't need to call this function unless flag DocumentFlags.KeepEscapeSequences is set.

Parameters

[in] aInput The input string.

Returns: The escape sequences and text segments. The escape characters are not removed from escape sequences.

Note: The WinRT component returns null instead of an empty array.

See also: withoutEscapeSequence(), DocumentFlags.KeepEscapeSequences

int updateDSS	(	SignDocVerificationParameters	aParameters,
		UpdateDSSFlags	aFlags
	)

Update the DSS for any eligible signatures of the document.

This function is available for PDF documents only.

To extend the validity of the signatures in a PDF document (long term validity LTV), call this function, save the document incrementally, and add a document time stamp.

If the document already has a document time stamp, this function adds information for the latest document time stamp to the DSS. If the document does not have a document time stamp, this function adds information for all eligible signature fields to the DSS.

This function fails if verification fails for any of the signatures.

Parameters

[in]	aParameters	Verification parameters or null for default parameters.
[in]	aFlags	Flags modifying the behavior of this function, see UpdateDSSFlags.Simulate and UpdateDSSFlags.VRI.

Returns: If UpdateDSSFlags.Simulate is not set in aFlags, the number of signature fields for which information has been added to the DSS will be returned. If UpdateDSSFlags.Simulate is set in aFlags, the number of eligible signature fields will be returned.

See also: updateDSS2()

void updateDSS2	(	string	aFieldName,
		SignDocVerificationParameters	aParameters,
		UpdateDSSFlags	aFlags
	)

Update the DSS for a signature of the document.

The main purpose of this function is testing SignDoc SDK, please use updateDSS() instead.

This function is available for PDF documents only.

Call this function (possibly a long time) after signing field aFieldName, then save the document incrementally and add a document time stamp. Before applying the first document time stamp, this function should be called for all eligable signature fields. If any document time stamp has already been added, this function should be called for the last document time stamp.

The signature field must have been signed with one of these methods: SigningMethod.DigSigPKCS7Detached, SigningMethod.DigSigPKCS7SHA1, SigningMethod.DigSigCadesDetached, or SigningMethod.DigSigCadesRFC3161.

This function does nothing if the signature field is not signed.

Parameters

[in]	aFieldName	The name of the signature field.
[in]	aParameters	Verification parameters or null for default parameters.
[in]	aFlags	Flags modifying the behavior of this function, see UpdateDSSFlags.Simulate and UpdateDSSFlags.VRI.

See also: addSignature(), updateDSS(), getFields()

SignDocVerificationResult verifySignature ( string aFieldName )

Verify a signature of the document.

There is a setFlags() flag modifying the behavior of this function: DocumentFlags.RelaxByteRange.

Parameters

[in] aFieldName The name of the signature field.

Returns: A new SignDocVerificationResult object describing the result of the verification.

See also: getSignature(), setFlags(), SignDocField.getSignatureType(), SignDocField.isSigned()

SignDocVerificationResult verifySignature2 ( SignDocSignature aSignature )

Verify a signature of the document.

These are the differences between calling this function and calling verifySignature() with the field name obtained from aSignature:

This function fails unless aSignature.getClearedIndex() returns -1.
PDF only: This function uses the DSS of the first document time stamp following the signature described by aSignature. If there is no such document time stamp, the latest DSS will be used. This behavior is required for verifying signatures with LTV (long term validity).

There is a setFlags() flag modifying the behavior of this function: DocumentFlags.RelaxByteRange.

Parameters

[in] aSignature A SignDocSignature object for this document.

Returns: A new SignDocVerificationResult object describing the result of the verification.

See also: getSignature(), setFlags(), verifySignature(), SignDocField.getSignatureType(), SignDocField.isSigned()

Prepend an escape sequence for specifying the natural language in a text string.

Parameters

[in]	aText	The text.
[in]	aLang	Language identifier (an RFC3066 language tag with two-character language code and optional two-character country code). Only the language and the optional country will be used, the dash separating them will be removed. Example: "en-US" will prepend ESC "enUS" ESC.

Returns: A copy of aText with an escape sequence prepended.

See also: withoutEscapeSequences()

static string withoutEscapeSequences ( string aInput )

static

Remove escape sequences specifying the natural language in text strings.

You don't need to call this function unless flag DocumentFlags.KeepEscapeSequences is set.

Parameters
