To all the programmers out there.
I'm programming a parts database that reads raw PDF files and sends all the copier parts info/images to a mass database.
I would like some help with decoding the Stream Data in a PDF document.
The problem is decodeding the raw PDF Stream compression Data.
I know how to have programmed the Ascii85 decoding thats not the problem.
I'm using Zlib deflate algorithm for decoding the Zip stream after decoding with Ascii85.
The problem I'm having is understanding how/why Adobe does not conform with the stardard ZLib Stream header.
Not all deflate compression streams decode properly after sending the data through the Zlib Decompression algorithm.
Can anyone help with decoding the PDF Zlib stream header ? How does Adobe read an use the Zlib deflate alorgithm.
I have Adobes PDF public File Specification (900 pages) already but it doesn't give the answer. (We'll, I can't find it if it does).
I've have searched the iNet high and low , but nothing of any help.
If I can get this last peice working I should have a super all in one copier,fax,register, parts database for all makes and models of machines. It'll have barcode, super parts-in out tracking linked to tech and customer the lot. Quick simple and easy is the priority.
