-----------------------------
hi , please find the attached pdfs one showing the image and another not
showing when i return the template as inputstream and setting it to
signatureOptions.setVisualSignature(inputstream of pdf template). i want to
show the image and the static appearence of the contents on the inserted pdfbox
in the pdf.But current scenario my image and the inserted pdfbox are on
different locations. please find the below code i am using. how to draw an
image without the use of the pagecontentstream ? is it possible?
code .....
