makecol8(3alleg4) Allegro manual makecol8(3alleg4)NAME
makecol8, makecol15, makecol16, makecol24, makecol32 - Converts an RGB value into a display dependent pixel format. Allegro game program-
int makecol8(int r, int g, int b);
int makecol15(int r, int g, int b);
int makecol16(int r, int g, int b);
int makecol24(int r, int g, int b);
int makecol32(int r, int g, int b);
These functions convert colors from a hardware independent form (red, green, and blue values ranging 0-255) into various display dependent
pixel formats. Converting to 15, 16, 24, or 32-bit formats only takes a few shifts, so it is fairly efficient. Converting to an 8-bit color
involves searching the palette to find the closest match, which is quite slow unless you have set up an RGB mapping table (see below).
/* 16 bit color version of green. */
int green_color = makecol16(0, 255, 0);
Returns the requested RGB triplet in the specified color depth.
