In my open-source project called PDFinclude (for the Progress Development environment - www.progress.com ) I've been able to develop code that allows for the embedding of JPEG images into my PDF documents.
Congrats!
I now need the ability to include GIF images.
Ah, now comes the hard stuff ;).
From what I've read I can't use the same method as for JPEG ... that is, including the entire JPEG image in the Xobject stream.
Correct. JPEG is the only file format that can be placed into a PDF w/o modification...
Can someone outline what is required for including a GIF image into a PDF document ...
Well, the easiest way to do this is...
* Decode the GIF into a memory bitmap/raster image
(obviously you'll need a GIF decoder for this)
* Write out that bitmap as an Image XObject (as you did for JPEG).That will create a working PDF and image, though it will be bigger than necessary since you'll be going from an indexed image to a full color image.
Any sample objects would be much appreciated.
There are a number of other open source PDF generators that can handle GIF that would be a good place to start.
