.TH "al_draw_pixel" "3" "" "Allegro reference manual" ""
.SH NAME
.PP
al_draw_pixel \- Allegro 5 API
.SH SYNOPSIS
.IP
.nf
\f[C]
#include\ <allegro5/allegro.h>
void\ al_draw_pixel(float\ x,\ float\ y,\ ALLEGRO_COLOR\ color)
\f[]
.fi
.SH DESCRIPTION
.PP
Draws a single pixel at x, y.
This function, unlike al_put_pixel(3), does blending and, unlike
al_put_blended_pixel(3), respects the transformations (that is, the
pixel\[aq]s position is transformed, but its size is unaffected \- it
remains a pixel).
This function can be slow if called often; if you need to draw a lot of
pixels consider using al_draw_prim(3) with ALLEGRO_PRIM_POINT_LIST from
the primitives addon.
.IP \[bu] 2
x \- destination x
.IP \[bu] 2
y \- destination y
.IP \[bu] 2
color \- color of the pixel
.RS
.PP
\f[I]Note:\f[] This function may not draw exactly where you expect it
to.
See the pixel\-precise output section on the primitives addon
documentation for details on how to control exactly where the pixel is
drawn.
