NAME
       vga_getscansegment - get a list of consecutive pixel values

SYNOPSIS
       #include <vga.h>

       int  vga_getscansegment(unsigned	 char  *colors,	 int  x,  int  y,  int
       length);

DESCRIPTION
       The direct opposite of vga_drawscansegment(). The line of length pixels
       starting	 at  (x, y) is not drawn but instead the colorvalues are taken
       from the screen and copied into color[0] .. color[length - 1].  Svgalib
       versions	 was  introduced  in version 1.2.10.  In high/truecolor modes,
       the length must be given in bytes, not pixels.
