I am trying to create a PDF file that will be used as the graphic image (of the signature appearance) any time I am signing with Adobe 6 signing handler.
The graphical signature is saved somewhere as a monochrome BMP.
I have no problem putting the image on an empty page, then cropping the page to the exact size of the signature image (so it will be scaled better in the signature appearance), my only problem is that the rectangle is not transparent, means that all the white pixels hide everything that underneath them, while I want that only the black signature will be painted and the the rest of the pixels will not affect the page appearance.
Is there any API call I can use to eliminate the white pixels painting?
