Parameters for signing a document.
Use SignDocDocument.createSignatureParameters() or SignDocDocument.createSignatureParametersForTimeStamp() to create objects of this type.
The available parameters depend both on the document type and on the signature field for which the SignDocSignatureParameters object has been created. All setters have a special value for one of their arguments which can be used for checking if the parameter can be set.
SignDocDocument.addSignature() may fail due to invalid parameters even if all setters reported success as the setters do not check if there are conflicts between parameters.
Which certificates are acceptable may be restricted by the application (by using csf_software and csf_hardware of integer parameter "SelectCertificate", blob parameters "FilterCertificatesByIssuerCertificate" and "FilterCertificatesBySubjectCertificate", and string parameters "FilterCertificatesByPolicy" and "FilterCertificatesBySubjectDN") and by the PDF document (certificate seed value dictionary). If no matching certificate is available (for instance, because integer parameter "SelectCertificate" is zero), SignDocDocument.addSignature() will throw SignDocNoCertificateException. If more than one matching certificate is available but csf_never_ask is specified in integer parameter "SelectCertificate"), SignDocDocument.addSignature() will throw SignDocAmbiguousCertificateException.
To make the signature maximally meaningful, integer parameter "AddCertificates" should be ac_all (which is the default value) and integer parameter "AddRevocationInfo" should include ari_add.
Unless you need a specific signing method, you should leave integer parameter "Method" at its default value m_default. If you select a specific signing method and that method is not allowed by the signature field's seed values, signing will fail.
Unless you need a specific digest algorithm, you should leave string parameter "DetachedHashAlgorithm" at its default value "default". If you select a specific digest algorithm and that algorithm is not allowed by the signature field's seed values, signing will fail.
The interaction between some parameters is quite complex; the following section tries to summarize the signing methods for PDF documents.
Additionally:
For TIFF documents, an additional, simplified signing method is available:
The following parameters control the signing method and related aspects of the signature:
The following parameters control the private key used for signing:
The following parameters control rendering of the signature image from biometric data:
The following parameters put additional data into the signature:
The following parameters provide texts for the appearance of a signature in PDF documents:
The following parameters control how a signed signature field in a PDF document will look like (parameters marked with * can be overridden with blob parameter "Template"):
The following parameters control the signing certificate:
The following parameters are used for generating a self-signed certificate on the fly (you also need to set at least one parameter for the private key):
The following parameters are used for putting biometric data (handwritten signature) into the signature:
The following parameters control the certificate selection dialog:
The following parameters control RFC 3161 timestamps:
The following parameters put additional certificates and revocation information into the signature:
The following parameters do not fall into the above categories:
synchronized void addTextItem | ( | String | aItem, |
int | aGroup | ||

Add another string to be displayed, top down.
For DigSig signature fields, this function adds another string to the appearance stream of PDF documents. The first call clears any default strings. The default values depend on the profile passed to SignDocDocument.createSignatureParameters():

Flag for ignoring mandatory requirements specified by the signature seed value dictionary: Ignore DigestMethod (hash algorithm).
Used for integer parameter "IgnoreSeedValues".
If this flag is not set, signing will fail if a hash algorithm is requested that is not listed in the DigestMethod entry of the signature field seed value dictionary. The hash algorithnm is specified by string parameter "DetachedHashAlgorithm" (if the value of that parameter is not "default"). It can also be implied by integer parameter "Method".
If this flag is set, you can override the DigestMethod entry of the signature field seed value dictionary with string parameter "DetachedHashAlgorithm" and/or integer parameter "Method" without risking failure of signing due to a conflict with DigestMethod.

Flag for ignoring mandatory requirements specified by the signature seed value dictionary: Ignore SubFilter (signing method).
Used for integer parameter "IgnoreSeedValues".
If this flag is not set, signing will fail if the signing method specified by integer parameter "Method" is neither m_default nor listed in the SubFilter entry of the signature field seed value dictionary.
If this flag is set, you can override the SubFilter entry of the signature field seed value dictionary with integer parameter "Method" without risking failure of signing due to a conflict between "Method" and SubFilter.

Transparency of signature image: Make the brightest color transparent.
If the image has an alpha channel (or if its palette contains a transparent color), the image's transparency will be used. Otherwise, white will be made transparent for truecolor images and the brightest color in the palette will be made transparent for indexed images (including grayscale images).
Transparency is not supported for JPEG images and JPEG-compressed TIFF images. Signature images created from biometric data (according to the "RenderSignature" integer parameter) don't have an alpha channel.

Transparency of signature image: Make signature image opaque.
The signature image will be opaque unless the image has an Used for integer parameter "ImageTransparency". alpha channel or transparent colors in its palette.
Transparency is not supported for JPEG images and JPEG-compressed TIFF images. Signature images created from biometric data (according to the "RenderSignature" integer parameter) don't have an alpha channel.

Signing method (for integer parameter "Method"): default method.
For signature parameters created by SignDocDocument.createSignatureParametersForTimeStamp(), this value is treated as m_digsig_cades_rfc3161.
Use the method specified by the SubFilter values of the signature field seed value dictionary or, if not present, m_digsig_pkcs7_detached.
This is the recommended method unless you need an ETSI CAdES signature (m_digsig_cades_detached).
|

Fix appearances of check boxes and radio buttons for PDF/A-1 without Technical Corrigendum 2 before signing: Freeze (fix) appearances if appropriate.
Used for integer parameter "PDFAButtons".
Freeze (fix) appearances if the document claims PDF/A-1 conformance and if there are no signed signature fields.
Using pb_auto if the document claims PDF/A-1 conformance and has no signed signature fields is equivalent to saving the document with SignDocDocument.sf_pdfa_buttons before signing.
This value should be used only if you need conformance with ISO 19005-1:2005 without Technical Corrigendum 2 (TC2), that is, if you need conformance with a standard that is no longer in force.
Note that TC2 is in force and using this value breaks conformance with TC2.

Flags for rendering the signature (for integer parameter "RenderSignature": Limit the size of the rendered signature to the size of the captured signature.
If this flag is set, the rendered signature won't be magnified. However, it may be shrunk to fit the signature field.
Set this flag only if you are sure that the capture resolution stored in the blob passed to blob parameter "BiometricData" is accurate.

Integer parameter "RemoveXFA": Always remove XFA.
Use this value if you intend to call SignDocDocument.setField() or SignDocDocument.addField() after signing. Adding the signature will fail if the document prohibits removal of XFA.

Integer parameter "RemoveXFA": Remove XFA if possible.
XFA will be removed unless the document prohibits removal of XFA. SignDocDocument.addField() and SignDocDocument.setField() will fail if XFA is still present after signing.

Integer parameter "RemoveXFA": Do not remove XFA.
SignDocDocument.addField() and SignDocDocument.setField() will fail if XFA is still present after signing.

One font size is used per group and is chosen such that the text fits horizontally. The maximum font size is specified by length parameter "FontSize". The font size of the slave group cannot be greater than the font size of the master group, that is, long text in the slave group won't reduce the font size of the master group.
There must be at least one master text item if there is a slave text item.
