This library is a open source RGB332 format bitmap library.
RGB332 format is suitable for embedded systems because it does not consume much memory.
You can create/delete bitmap images, get the color of a point, draw points/lines/rectangles/text, etc.
This library also includes bicubic interpolation function.
The library consists of only two files: bmp_rgb332.c and bmp_rgb332.h.
RGB332 bitmap uses 256 color palette data (1024 bytes), data size will be larger than RGB565 or RGB888 if the image size is small.
test.c is test program.
After downloading this repository, you can run the test program by executing the following command.
gcc -o program test.c bmp_rgb332.c && ./program
