Texturing in C

[Mephisto]

Could someone tell me a link to a page where i can find the sourcecode for a program which
loads an windows bmp file and use it as texture. The sourcecode should be written in C. Don´t send a link to a C++ program, please. I need it in C. If you have such a file at home please mail it to me.
Breier@odn.de
It would be the best if i can have a source code with explanations or a tutorial.

I have sent you some files that may be of help.

Could I get that code too?

I have tossed the code you ways. Some of the code is a bit 'hackish', but hopefully it helps. Windows bitmaps are not to bad to read. Basically you have your headers, the your color palette (unless it is a 24-bit), and then your data. If it's an 8 bit bitmap, you have 256 colormap entries and each byte in the image data is a reference into this table. If it's 4-bit, each byte in the data contains two pixels referencing into a 16 entry colormap (you have to mask out each pixel).
Two cautions:
Bitmaps are stored upside-down.
Each row of bitmap data is 4-byte aligned to the beginning of the data section.
My code only handles 8-bit bitmaps, but expand away!

.. I think, I need an example how to use windows-bmp as textures, too Could you mail me some example ?

Thanx in advance.

In my opinion, TGA images are much easier to work with. Windows DIB (BMP) are too proprietary for me, as I like to multi-platform my apps. The RLE encoding of a Windows bitmap is utterly ubsurd in my opinion, as it makes no sense to me what-so-ever. I do have a TGA image reading/writing library I wrote for my apps and the code is GPL'd. It's platform independant and written in C, but works with C++ as well. It supports 8, 16, 24 and 32-bit RGB(A) and RLE compressed TGA images. Drop me a mail if you'd like a copy.

seriously. Anyways, what's the story with the "it has to be C and not C++"? C++ is not THAT obsiscated that translating it is prohibitively difficult!?
