Heyho,
can someone show me the most effective way of how to use al_draw_text to draw the rgb information from al_get_pixel.
I tried to do this:
currentPixel = al_get_pixel(image, w, h); al_unmap_rgb(currentPixel, &r, &g, &b); al_draw_text(currentFont, al_map_rgb(255, 255, 255), 50, 50, ALLEGRO_ALIGN_LEFT, r);
but al_draw_text wants to have a const char.
Bruce Perry
//Extract the colour values unsigned char r, g, b; al_unmap_rgb(currentPixel, &r, &g, &b); //Use the formatted text function al_draw_textf(currentFont, al_map_rgb(255, 255, 255), 50, 50, ALLEGRO_ALIGN_LEFT, "(%d, %d, %d)", r, g, b);
...I didn't notice you'd already found al_unmap_rgb when I wrote that

Wow, very straightforward, thanks a lot Bruce Perry!
