Locating signature with stretch mode Leave feedback
GroupDocs.Signature provides ability to stretch signature area along page width or height. Use enumeration StretchMode contains following values
- None - no stretch will be applied
- PageWidth - to stretch signature area along page width
- PageHeight - to stretch signature area along page height
- PageArea - to stretch signature area along page width and height
Here are the steps to use stretch mode with adding text or images signatures into document with GroupDocs.Signature:
- Create new instance of Signature class and pass source document path as a constructor parameter.
- Instantiate the TextSignOptions or ImageSignOptions object with all required additional options and setup setStretch property
- Call sign method of Signature class instance and the instance of signature options (ImageSignOptions for example) to it.
This example shows how to locate signature with stretch mode.
// instantiating the signature object
final Signature signature = new Signature("sample.pdf");
// define several signature options of different types and settings
TextSignOptions textOptions = new TextSignOptions("This is test message");
textOptions.setAllPages(true);
textOptions.setVerticalAlignment(VerticalAlignment.Top);
textOptions.setMargin(new Padding(50));
textOptions.setStretch(StretchMode.PageWidth);
BarcodeSignOptions barcodeOptions = new BarcodeSignOptions("123456");
barcodeOptions.setAllPages(true);
barcodeOptions.setEncodeType(BarcodeTypes.Code128);
barcodeOptions.setVerticalAlignment(VerticalAlignment.Bottom);
barcodeOptions.setMargin(new Padding(50));
barcodeOptions.setStretch(StretchMode.PageWidth);
ImageSignOptions imageOptions = new ImageSignOptions();
imageOptions.setAllPages(true);
imageOptions.setStretch(StretchMode.PageHeight);
imageOptions.setHorizontalAlignment(HorizontalAlignment.Right);
imageOptions.setImageFilePath("image.png");
// define list of signature options
List<SignOptions> listOptions = new ArrayList<SignOptions>();
listOptions.add(textOptions);
listOptions.add(barcodeOptions);
listOptions.add(imageOptions);
// sign document to file
SignResult signResult = signature.sign("signed.pdf", listOptions);
// analyzing result
System.out.print("List of newly created signatures:");
int number = 1;
for(BaseSignature temp : signResult.getSucceeded())
{
System.out.print("Signature #"+ number++ +": Type: "+temp.getSignatureType()+" Id:"+temp.getSignatureId()+
",Location: "+temp.getLeft()+"x"+temp.getTop()+". Size: "+temp.getWidth()+"x"+temp.getHeight());
}
