I would like to ask if anyone has any reference or links or algorithms to decode BMP files (*.bmp).


I got information useful from wikipedia. I did getting the header, Palette and pixel data. But i don't know how to decode it into raw data using the Palette information and pixel data information.

I dun require the C code, as i am going to do it, i just need the decoding algorithm or maybe some information on it.

I went to google, but i dun get much info in the decoding part.


Thanks in advance!!!!!!

http://www.brackeen.com/vga/bitmaps.html the data array starts from the end of file have this in your mind

What do you mean by "decode"?

Here's the problem as I see it:




The bmp file contains information about the width and height in pixels and some information that would tell how to render each pixel (Red,Green,Blue values).

What are your requirements for output?

Reading the information from wikipedia or wotsit (or wherever) can tell us what kinds of bmp formats there for various color depths. So: what do you want to do with that information?

Regards,

Dave
