PDFBox support image creation. We have also created an option to add empty signature fields that can be signed later. So a customer can select in the first process the place were the visual signature should be placed and give the document to the persons that should sign it. The swing component also shows existing signature fields and make it selectable for signing. All is done with transparent rectangles without a preloaded an image. The rectangle was also adjustable and had two text fields with the size in mm. > > If this is good idea might be I could manage to do this too. > what do you think? If you can manage it, why not :-) I know this was a annoying process placing the images and recalculate the size to match the document. One problem we had was with landscape pages. So the page was flipped and the coordinates need to be moved. Thanks god we finished this project. > > Best regards Best regards Thomas
