.SH SYNOPSIS
|

|
|
|
||
|
|
.B "#include <vga.h>"
|

.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.
