|
|
.SH NAME
|
|
vga_drawscansegment \- draw a horizontal line of pixels
|
|
.SH SYNOPSIS
|
|
|
|
.B "#include <vga.h>"
|
|
|
|
.BI "int vga_drawscansegment(unsigned char *" colors ", int " x ", int " y ", int " length );
|
|
|
|
.SH DESCRIPTION
|
|
draws a horizontal line of
|
|
.I length pixels
|
|
starting at position
|
|
.BI ( x ", " y ).
|
|
The colors drawn are taken from
|
|
.IB color "[0] .. " color [ length " - 1]."
|
|
Svgalib versions prior to 1.2.10 required
|
|
.IR 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.
