-----------------------------
hi , i agree but when i pass the image of jpeg type it throws the llegalstate
exception at the buildsignature and at the pdjpeg constructor as i previously
mentioned. I also agree that i have to write in the appearence stream instead
of pagecontentstream but how could i add image to pdf without calling the
pagecontentstream.drawImage() method? i have tried but image not added without
this method. i have also tried to set bounding box as below
BoundingBox box = new BoundingBox(0, 0, sigWidth, sigheight);
PDRectangle pdRectangle = new PDRectangle(box);
form.setBBox(pdRectangle);
but my image and the signaturefield are on the different locations. I have one
doubt, can we add the image and the contents in the appearencestream using the
xobjects in the resources instead of calling drawImage method of the
pagecontentstream? I have just want to show the image and some contents in the
signaturefield or the inserted blankbox the same way you did by editing the
given pdf.
