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.
