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.
