vga_drawscansegment(3)	       Svgalib User Manual	  vga_drawscansegment(3)

NAME
     vga_drawscansegment - draw a horizontal line of pixels

SYNOPSIS
     #include <vga.h>

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

DESCRIPTION
     draws  a horizontal line of length pixels starting at position (x, y).  The
     colors drawn are taken from color[0] .. color[length -  1].   Svgalib  ver-
     sions  prior to 1.2.10 required x, y, and length to be multiples of 8. This
     is no longer true.  In high/truecolor modes, the length must  be  given  in
     bytes, not pixels.

     It  is  very  likely  that both are at least to some extent are due to Harm
