( string $pattern_id
, float $x
, float $y
, float $width
, float $height
) : bool
Warning 本函数还未编写文档，仅有参数列表。
Indicates that subsequent commands up to a DrawPopPattern() command comprise the definition of a named pattern. The pattern space is assigned top left corner coordinates, a width and height, and becomes its own drawing space. Anything which can be drawn may be used in a pattern definition. Named patterns may be used as stroke or brush definitions.
参数
pattern_id- the pattern Id
x- x coordinate of the top-left corner
y- y coordinate of the top-left corner
width- width of the pattern
height- height of the pattern
返回值
成功时返回 true， 或者在失败时返回 false。
范例
Example #1 ImagickDraw::pushPattern()
<?phpfunction pushPattern($strokeColor, $fillColor, $backgroundColor) { $draw = new \ImagickDraw(); $draw->setStrokeColor($strokeColor); $draw->setFillColor($fillColor); $draw->setStrokeWidth(1); $draw->setStrokeOpacity(1); $draw->setStrokeColor($strokeColor); $draw->setFillColor($fillColor); $draw->setStrokeWidth(1); $draw->pushPattern("MyFirstPattern", 0, 0, 50, 50); for ($x = 0; $x < 50; $x += 10) { for ($y = 0; $y < 50; $y += 5) { $positionX = $x + (($y / 5) % 5); $draw->rectangle($positionX, $y, $positionX + 5, $y + 5); } } $draw->popPattern(); $draw->setFillOpacity(0); $draw->rectangle(100, 100, 400, 400); $draw->setFillOpacity(1); $draw->setFillOpacity(1); $draw->push(); $draw->setFillPatternURL('#MyFirstPattern'); $draw->setFillColor('yellow'); $draw->rectangle(100, 100, 400, 400); $draw->pop(); $imagick = new \Imagick(); $imagick->newImage(500, 500, $backgroundColor); $imagick->setImageFormat("png"); $imagick->drawImage($draw); header("Content-Type: image/png"); echo $imagick->getImageBlob();}?>
