Hi all,
Could you tell me how to write simple graphics program in c, for example, how to take the format of bmp, pgm, csd file from image file?
how to convert from one format to other? If anybody knows a good book or web site, please tell me soon.

you would have to read the binary picture file byte-for-byte and convert it into the image. Then you could rewrite it in other formats.

If you wanted to do it yourself, you'd have to get file format specs for each format you wanted to support. Yuck.

I'd suggest looking for a library you can use. Assuming you're targeting Win32, I don't think there's much in the realm of graphics manipulation in the API. But I did find a couple of promising candidates:
PixelToaster
FreeImage (C++)
There's bound to be others available as well.

I knew that other programs were used in conjuction with C/C++ to create images, nobody could create images freehand just by using text (unless it's like, turtle graphics).

If you want file specs, there's a great website for every file imaginable:

Wotsit.org

Just type in the file extension or the type of file, and you'll usually get results.
