BITMAPIMG

Simple and very fast library for C or C++ to create dots and lines in a bitmap file.

How to use it

Import the library in your code

#include "bitmap.h"

Create a color pixel:

    bmp_pixel red;
    red.r = 255;
    red.g = 0;
    red.b = 0;
    
    bmp_pixel white;
    red.r = 255;
    red.g = 255;
    red.b = 255;
    

Create BMPFILE object to draw the dots and lines

BMPFILE *file = bmp_init_bmp(1024, 1024, white, BMP_SCALE_NO); // width, height, background-color

Add a line

bmp_add_line(file, 0, 10 , 0, 200, 1, red); // bmp_pointer, x0, x1, y0, y1, strength(px), color

Add a dot

bmp_add_dot(file, 2, 255, 3, red); // bmp_pointer, x, y, radius(px), color

Save the bitmap image:

bmp_generate_bmp(file,"test.bmp");

See the main.c file as a example.
