NAMEmakecol8, makecol15, makecol16, makecol24, makecol32 − Converts an RGB value into a display dependent pixel format. Allegro game programming library.​

---

SYNOPSIS#include <allegro.h> 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);

---

DESCRIPTIONThese 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). Example: /* 16 bit color version of green. */ int green_color = makecol16(0, 255, 0);

---

RETURN VALUEReturns the requested RGB triplet in the specified color depth.
