范例
Example #1 ImagickDraw::setFillOpacity()
<?php function setFillOpacity($strokeColor, $fillColor, $backgroundColor) { $draw = new \ImagickDraw(); $draw->setStrokeColor($strokeColor); $draw->setFillColor($fillColor); $draw->setStrokeOpacity(1); $draw->setStrokeWidth(2); $draw->rectangle(100, 200, 200, 300); $draw->setFillOpacity(0.4); $draw->rectangle(300, 200, 400, 300); $imagick = new \Imagick(); $imagick->newImage(500, 500, $backgroundColor); $imagick->setImageFormat("png"); $imagick->drawImage($draw); header("Content-Type: image/png"); echo $imagick->getImageBlob(); } ?>
When fill color is changed, this is reset to 1.0 or to defined alpha with #aaxxx color format, where aa is alpha.
