create_canvas(w,h) → canvas
draw_pixel(canvas,x,y,color)
draw_line(canvas,x1,y1,x2,y2,color)
draw_rect(canvas,x,y,w,h,color)
draw_circle(canvas,cx,cy,r,color)
draw_gradient_rect(...)
rgb(r,g,b) → color
save_image(canvas, filename)

Example

let c = create_canvas(800, 600);
draw_rect(c, 0, 0, 800, 600, rgb(10, 10, 30));
draw_circle(c, 400, 300, 120, rgb(255, 0, 0));
draw_line(c, 50, 50, 750, 550, rgb(0, 255, 255));
save_image(c, "out.ppm");

Notes

PPM is uncompressed and large; combine with Compression library if needed.
