NAME¶
gl_getpalettecolor, gl_getpalettecolors, gl_getpalette - read the color palette
SYNOPSIS¶
#include <vgagl.h>
void gl_getpalettecolor(int c, int *r, int
*g, int *b);
void gl_getpalettecolors(int s, int n, void
*dp);
void gl_getpalette(void *dp);
DESCRIPTION¶
gl_getpalettecolor gets red, green and blue values (in the range 0 - 63)
of color
c from the color-lookup-table, and stores them as integers in
the memory locations pointed to by
r,
g and
b.
gl_getpalettecolors gets RGB values of
n colors starting at
s, which are stored as a table of groups of three bytes each at
dp.
gl_getpalette is equivalent to
getpalettecolors(0, 256,
dp
).
vga_ext_set(3) might change the range of the colors returned to 0 - 255.
