Hi all,
Hi
Forgive my naiveness but I am new to PdfBox, and trying my best to understand
the library. I am stuck at a point and need someone to show a work around, pls
see the mail below for details.
No problem, i think no one have a helping solution, so no one answer you.
I mailed this to the list a few days back, and receiving no response feels
weird. I am not sure if my mails are getting through.
The mailing list works great. If you subscribed the list correctly, you
should also got your mail from the mailing list, as well as the other
subscriber.

Subject: Re: Embed PNG/GIF image into existing PDF Document
I am loading PNG image using ImageIO and loading into PDJpeg using
PDJpeg(PDDocument, BufferedImage).
You are trying to load a PNG with the PDJpeg which is only for JPGs.
Some times ago i used iText for adding images like PNG and JPG in PDF
documents and find out, that ...
- JPGs are stored directly byte-by-byte in the document
- PNGs are stored manipulated, i mean iText do something with the images
befor storing it in the document.
So i think it would be tricky to implement a similar class for PNGs.
BUT you can convert the images with java on the fly in JPG like i did it
and then store the image with the PDJpeg. If the image is transparent,
you should add a white background color befor storing it.
Thank you very much.
