    Obtain document form fields and signatures information

    GroupDocs.Signature allows to get extended document information which includes:

    • list of all existing Form Field Signatures in the document. This list will contain all Form Fields elements in the document no matter if these components were added by GroupDocs Signature or any other third party software. Please be aware only Pdf and Word processing documents support these elements.
    • list of Text Signatures previously added to document over Sign method or updated by Update method;
    • list of Image Signatures previously added to document over Sign method or updated by Update method;
    • list of DigitalSignature previously added to document over Sign method or updated by Update method;
    • list of BarcodeSignature previously added to document over Sign method or updated by Update method;
    • list of QrCodeSignature previously added to document over Sign method or updated by Update method;
    • list of FormFieldSignature previously added to document over Sign method or updated by Update method;

    Analyze document form fields and signatures information

    The following code snippet demonstrates how to obtain information about document form fields, signatures and analyze them.

    
	final Signature signature = new Signature("sampleSigned.pdf");
       
	IDocumentInfo documentInfo = signature.getDocumentInfo();
	System.out.print("Document properties "+ filePath);
	System.out.print(" - format : "+documentInfo.getFileType().getFileFormat());
	System.out.print(" - extension : "+documentInfo.getFileType().getExtension());
	System.out.print(" - size : "+documentInfo.getSize());
	System.out.print(" - page count : "+documentInfo.getPageCount());
	for (PageInfo pageInfo : documentInfo.getPages())
	{
		System.out.print(" - page-"+pageInfo.getPageNumber()+" Width "+pageInfo.getWidth()+", Height "+pageInfo.getHeight());
	}
	// display document Form Field signatures information
	System.out.print("Document Form Fields information: count = "+documentInfo.getFormFields().size());
	for (FormFieldSignature formField : documentInfo.getFormFields())
	{
		System.out.print(" - type #"+formField.getType()+": Name: "+formField.getName()+" Value: "+formField.getValue());
	}
	// display document Text signatures information
	System.out.print("Document Text signatures : "+documentInfo.getTextSignatures().size());
	for (TextSignature textSignature : documentInfo.getTextSignatures())
	{
		System.out.print(" - #"+textSignature.getSignatureId()+": Text: "+textSignature.getText()+" Location: "+textSignature.getLeft()+"x"+textSignature.getTop()+". Size: "+textSignature.getWidth()+"x"+textSignature.getHeight());
	}
	// display document Image signatures information
	System.out.print("Document Image signatures : "+documentInfo.getImageSignatures().size());
	for (ImageSignature imageSignature : documentInfo.getImageSignatures())
	{
		System.out.print(" - #"+imageSignature.getSignatureId()+": Size: "+imageSignature.getSize()+" bytes, Format: "+imageSignature.getFormat());
	}
	// display document Digital signatures information
	System.out.print("Document Digital signatures : "+documentInfo.getDigitalSignatures().size());
	for (DigitalSignature digitalSignature : documentInfo.getDigitalSignatures())
	{
		System.out.print(" - #"+digitalSignature.getSignatureId());
	}
	// display document Barcode signatures information
	System.out.print("Document Barcode signatures : "+documentInfo.getBarcodeSignatures().size());
	for (BarcodeSignature barcodeSignature : documentInfo.getBarcodeSignatures())
	{
		System.out.print(" - #"+barcodeSignature.getSignatureId()+": Type: "+barcodeSignature.getEncodeType().getTypeName()+". Text: "+barcodeSignature.getText());
	}
	// display document QrCode signatures information
	System.out.print("Document QR-Code signatures : "+documentInfo.getQrCodeSignatures().size());
	for (QrCodeSignature qrCodeSignature : documentInfo.getQrCodeSignatures())
	{
		System.out.print(" - #"+qrCodeSignature.getSignatureId()+": Type: "+qrCodeSignature.getEncodeType().getTypeName()+". Text: "+qrCodeSignature.getText());
	}
	// display document Form Fields signatures information
	System.out.print("Document Form Fields signatures : "+documentInfo.getFormFieldSignatures().size());
	for (FormFieldSignature formFieldSignature : documentInfo.getFormFields())
	{
		System.out.print(" - #"+formFieldSignature.getSignatureId()+" Type "+formFieldSignature.getType()+": Name: "+formFieldSignature.getName()+" Value: "+formFieldSignature.getValue());
	}
