imagesetbrush 


gd apg

SET the brush image for line drawing.





This function sets the brush image to be used by all line drawing functions, such as imageline and imagepolygon when filling with the special colors IMG_COLOR_BRUSHED or IMG_COLOR_STYLEDBRUSHED.

Special attention should be taken when we are finished with a brush, but if we destroy the brush image, (or let PHP destroy it), we must not use the IMG_COLOR_BRUSHED or IMG_COLOR_STYLEDBRUSHED colors until we have set a new brush image.

This function returns TRUE on success or FALSE on failure.
