By adding just a few lines of code, empower your Java applications with features to view, add, update, validate, remove and search digital signatures within PDF, Microsoft Word, Excel worksheets, PowerPoint presentations, Adobe Photoshop, metafiles and image file formats. The e-signature API also supports additional features to customize signature properties as per requirements.
The code example below clearly demonstrates the steps about how to edit digital signatures in an already signed CMX file in Java using GroupDocs.Signature library by adding just a few lines of code.
GroupDocs.Signature for Java APIs are supported on all major platforms and operating systems. Before executing the code below, please make sure that you have the following prerequisites installed on your system.
Signature signature = new Signature("sampleSigned.pdf");
try
{
ImageSearchOptions options = new ImageSearchOptions();
// search for image signatures in document
List signatures = signature.search(ImageSignature.class,options);
if (signatures.size() > 0)
{
ImageSignature imageSignature = signatures.get(0);
imageSignature.setLeft(100);
imageSignature.setTop(100);
boolean result = signature.update("sampleSigned-output.cmx",imageSignature);
if (result)
{
System.out.print("Image signature at location " + imageSignature.getLeft() + "x" + imageSignature.getTop() + " and Size " + imageSignature.getSize() + " was updated in the document [" + fileName + ".");
}
else
{
System.out.print("Signature was not updated in the document! Signature at location " + imageSignature.getLeft() + "x" + imageSignature.getTop() + " and Size " + imageSignature.getSize() + " was not found!");
}
}
