Reading Bmps in C

[Josh Campbell]

I am going to try to make a program that converts a bitmap into a format suitable for the gba.

My big problem is how to read a .bmp file into my C program. I am not sure how they are formatted and how I would go about reading them in since i think they are binary, and not text.

Thanks

Hello,

thou i see this post its 7 years old, i think i am trying to make same thing as Josh Campbell.
i am trying to make a c program that reads .bmp files and then create them in a format i can use for my DS application .

for start i am having problems even at the reading the bitmap . thou i think i only need to read the rgb from the bitmap and put that in a file , and then use it for DS , because i will be using only 1 type of bmps and with certain size .

do you have anything that could put me on the right track ?

Thank you

I have no experience with the DS, and I stopped working with the GBA shortly before the DS came out.

Some resources that might be helpful:

• gbadev - I've heard that the DS is very similar to the GBA, so maybe some of the graphics tools they have will prove useful. Also have forums devoted to the DS.
• FreeImage - I've used it before. Makes loading/saving image files really easy. Supports a bunch of formats, too.

I guess you can add this to your resources:

the library can be linked with any program you write and provide reading/writing and manipulation of different formats.
There also have bindings for other languages in case you need.
