Standard Filters, PDF (UNRESOLVED)
I want to make some classes that will create/edit PDF files, but I can't get over a big problem... have to decode/encode the data in the PDF. So, does anyone have the code for the folowing encodings in VB .NET (or C#) ?
LZW Decode/Encode
Run Length Decode/Encode
CCITTFax Decode/Encode
CDT Decode/Encode
Flate Decode/Encode
Thanks...

You know... Time constraints... deadlines... focusing on the bigger task at hand...

If you want to make your own, why are you asking for other people's code?
A basic copy and paste != making your own.
Besides, just use what Adobe has available, why bother re-inventing the wheel?

Gee, everyone is against me now...
I don't think you know how much there is to it, to make a PDF. I'm asking for the FILTERS, I already made 2 of them, there are 7 in total, I'm only asking for the other 5 that I don't know how to do... I've made the PDF editing and creating a new PDF from scratch, but if I want to edit a PDF with an encoding listed earlier, I can't !
and about this:
"A basic copy and paste != making your own." -> Filters are only 10% of what I have to do...
And I don't want that stinking Adobe stuff, OK ! I want to make my own, why the hell is that wrong !!!!!!!
Those are supposed to be STANDARD filters, but I can't find them anywhere (not in VB or VB.NET anyway), I found the CDT encoding but it's in C, and it's too much to convert...

Not against you CV, I just don't have the code, I'm guessing most others here don't either.
I am all for doing things for yourself... its the best way to improve your application architecture design skills. I think it was Cander (?) who wrote his own database using VB.
I'd be more than glad to help you if I knew the first thing about what makes a PDF file, but I don't have the time to learn about them, and if I ever needed those functions, I would use Adobe's drivers simply because they will stay on top of changing formats, and again, I don't have the time or resources to keep any code I developed current.

Why dont you just use the C codes in VS .NET and make dlls out of them?
maybe this can help you:
