DESCRIPTION

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