范例
Example #1 ImagickDraw::setStrokeWidth()
<?php function setStrokeWidth($strokeColor, $fillColor, $backgroundColor) { $draw = new \ImagickDraw(); $draw->setStrokeWidth(1); $draw->setStrokeColor($strokeColor); $draw->setFillColor($fillColor); $draw->line(100, 100, 400, 145); $draw->rectangle(100, 200, 225, 350); $draw->setStrokeWidth(5); $draw->line(100, 120, 400, 165); $draw->rectangle(275, 200, 400, 350); $image = new \Imagick(); $image->newImage(500, 400, $backgroundColor); $image->setImageFormat("png"); $image->drawImage($draw); header("Content-Type: image/png"); echo $image->getImageBlob(); } ?>
If you set the stroke width to 0, there will often still be a hairline. To remove this hairline, use transparency, f.e. using: setStrokeColor("#00000000") hex 0-6 = color -> black hex 6-8 = opacity -> full transparency
Please note that this function only works (as in: the stroke width changes) when setStrokeColor() is called before.
