Custom Brushes

Although Styles are useful, they are limited to specifying patterns in the form on an array. More complex styles must be created in the form of brushes.

Custom brushes are created by creating an image and then setting that image as the brush to use in another drawing operation using the imagesetbrush() function

imagesetbrush($img_r, $brush_r);

Once a brush has been defined, it can be used by setting the color of a drawing function to the IMG_COLOR_BRUSHED constant
