Search for Image e-signatures

GroupDocs.Signature provides ImageSearchOptions class to specify different options to search for Image e-signatures.

 Here are the steps to search for Image signatures within the document with GroupDocs.Signature API:

  • Create new instance of Signature class and pass source document path as a constructor parameter;
  • Instantiate the ImageSearchOptions object according to your requirements and specify additional search options (if needed);
  • Call search method of Signature class instance and pass ImageSearchOptions to it.

The code snippet below demonstrates how to search for Image electronic signature in the document.

Signature signature = new Signature(sample.pdf);
// setup search options
ImageSearchOptions searchOptions = new ImageSearchOptions();   
// search document
List<ImageSignature> signatures =,searchOptions);
System.out.print("\nSource document ['" + fileName + "'] contains following image signature(s).");
// output signatures   
for (ImageSignature imageSignature : signatures)
   System.out.print("Found Image signature at page "+imageSignature.getPageNumber()+" and size "+imageSignature.getSize()+".");
   System.out.print("Location at "+imageSignature.getLeft()+"-"+imageSignature.getTop()+". Size is "+imageSignature.getWidth()+"x"+imageSignature.getHeight()+".");
