ImageMagick Functions

ImagickDraw::pushPattern

Description:

bool ImagickDraw::pushPattern ( string $pattern_id , float $x , float $y , float $width , float $height )

Indicates that subsequent commands up to a PopPattern() command comprise the definition of a named pattern. The pattern space is assigned top left corner coordinates, a width and height, and becomes its own drawing space. Anything which can be drawn may be used in a pattern definition. Named patterns may be used as stroke or brush definitions.

Parameters:

pattern_id

the pattern Id to be used by setFillPatternURL

x

x coordinate of the top-left corner

y

y coordinate of the top-left corner

width

width of the pattern

height

height of the pattern

Return Values

Returns TRUE on success or FALSE on failure.
