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()
<?php
function 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();
}
