Hi all,
We have working code based on
org.apache.pdfbox.examples.pdmodel.RubberStampWithImage
which inserts jpeg b/w signatures with white backgrounds into pdf docs. Now we
need to refine this to make the white background transparent. I see that
PDJpeg.getRBGImage() makes use of soft masks:
// If there is a 'soft mask' image then we use that as a transparency
mask.
[Soft masks are new item for me.] My question is:
Has anyone made use of this, and if so, do you have advice for me, and/or
examples you could provide?
Hmm, what exactly are you looking for? [1] shows how to render such an image and
[2] is about adding one to a pdf.
Many thanks in advance,
Ken
