Without the use of any other library you can look at the BMP file format. I've implemented it in the past and it can be done without too much work.

Bitmap-File Structures

Each bitmap file contains a bitmap-file header, a bitmap-information header, a color table, and an array of bytes that defines the bitmap bits. The file has the following form:

RGBQUAD aColors[];
BYTE aBitmapBits[];

... see the file format for more details
