示例 #1 ImagickDraw::setVectorGraphics() example

<?php
function setVectorGraphics() {
//Setup a draw object with some drawing in it.
$draw = new \ImagickDraw();
$draw->setFillColor("red");
$draw->circle(20, 20, 50, 50);
$draw->setFillColor("blue");
$draw->circle(50, 70, 50, 50);
$draw->rectangle(50, 120, 80, 150);

//Get the drawing as a string
$SVG = $draw->getVectorGraphics();

//$svg is a string, and could be saved anywhere a string can be saved

//Use the saved drawing to generate a new draw object
$draw2 = new \ImagickDraw();
//Apparently the SVG text is missing the root element.
$draw2->setVectorGraphics("<root>".$SVG."</root>");

$imagick = new \Imagick();
$imagick->newImage(200, 200, 'white');
$imagick->setImageFormat("png");

$imagick->drawImage($draw2);

header("Content-Type: image/png");
echo
$imagick->getImageBlob();
}
