Windows programming question...:) (png support)

[Trev]

Windows' support for JPEG is similar to its support for PNG. If you can't use GDI+, I would look at libpng <http://www.libpng.org/pub/png/libpng.html>. It's distributed under the zlib license, which has restrictions similar to the BSD and MIT licenses.

Amiga datatypes come to mind..

Yeah, datatypes are cool. There's nothing similar in the Windows Platform SDK.

I was googling about using it in Win2k and found some previous GDI+ version(s?) had a flaw that allowed to execution of code from malicious jpeg images

As opposed to Amiga OS, which offers no protection from malicious code whatsoever? ;-) Software is inherently flawed. . . .

Anyway, before GDI+ how did most developers support jpeg and png etc., did M$ provided some standard lib ? I find it hard to believe they only added support for that after XP

By reading up on the file specs and supporting them natively? Or as adolescent said, by using a third party library. GDI was designed to put bitmap data on the screen. I don't think Microsoft much cared how you stored the data itself.
