makecol15_dither(3alleg4)                                         Allegro manual                                         makecol15_dither(3alleg4)

NAME

       makecol15_dither, makecol16_dither - Calculates a dithered 15 or 16-bit RGB value. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int makecol15_dither(int r, int g, int b, int x, int y);

       int makecol16_dither(int r, int g, int b, int x, int y);

DESCRIPTION

       Given both a color value and a pixel coordinate, calculate a dithered 15 or 16-bit RGB value. This can produce better results when reducing
       images from truecolor to hicolor. In addition to calling these functions directly, hicolor dithering  can  be  automatically  enabled  when
       loading  graphics  by  calling  the  set_color_conversion() function, for example set_color_conversion(COLORCONV_REDUCE_TRUE_TO_HI | COLOR-
       CONV_DITHER).

       Example:

          int pixel1, pixel2;

          /* The following two color values MAY be different. */
          pixel1 = makecol16_dither(255, 192, 64, 0, 0);
          pixel2 = makecol16_dither(255, 192, 64, 1, 0);

RETURN VALUE

       Returns the RGB value dithered for the specified coordinate.
