imagesetbrushSet the brush image for line drawing

Beschreibung

imagesetbrush ( GdImage $image , GdImage $brush ) : bool

imagesetbrush() sets the brush image to be used by all line drawing functions (such as imageline() and imagepolygon()) when drawing with the special colors IMG_COLOR_BRUSHED or IMG_COLOR_STYLEDBRUSHED.

Achtung

You need not take special action when you are finished with a brush, but if you destroy the brush image (or let PHP destroy it), you must not use the IMG_COLOR_BRUSHED or IMG_COLOR_STYLEDBRUSHED colors until you have set a new brush image!

Use a brush to create a thick line.

To create a 3x3 red brush:

<?php
$brush_size
= 3;
$brush = imagecreatetruecolor($brush_size,$brush_size);
$brush_color = imagecolorallocate($brush,255,0,0);
imagefill($brush,0,0,$brush_color);
imagesetbrush($im,$brush);
?>

Then use imageline() or imagepolygon() with IMG_COLOR_BRUSHED as the color.

To stop using the brush, destroy it:

<?php imagedestroy($brush); ?>

The brush can also be created from an existing image.
