I am not sure if the bug is in iText, or why, but the problem is clear.
When you added the watermark, you color converted your Gray JPEG into an RGB
JPEG. BUT in the PDF, the watermarked version is STILL identified as GRAY -
which is why the funny display...

Hello,
I noticed a problem while processing JPEG image in a iText document. Some
of the generated PDF files look ugly with only a part of the JPEG magnified
with white and black stripes (see wm.pdf).
These JPEG files are preprocessed using ImageMagick in order to add a
watermark. I think this problem happens because of the embedded EXIF data
in the JPEG files. JPEG images without embedded data (using IM -strip
option) work great.
My question is : shouldn't iText ignore these buggy metadata in order to
show a nice JPEG image instead of this trash ?
Attached are the original JPEG (image.jpg), the IM preprocessed JPEG
(wm.jpg) and the generated PDFs (image.pdf, wm.pdf) with the piece of code
to build them.
Thanks a lot.
