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.
