php+Imagick 对psd文件的操作

$im = new Imagick("test.psd");

$num_layers = $im->getNumberImages();

for ($i = 0,$num_layers = $im->getNumberImages(); $i < $num_layers; ++$i) {

$im->setImageIndex($i);         //this
$im->setIteratorIndex($i);      //or this is kinda redundant
$pagedata=$im->getImagePage();
//print("x,y: " + $pagedata["x"].", ".$pagedata["y"]."<br/>\n");
//print("w,h: " + $pagedata["width"].", ".$pagedata["height"]."<br/>\n");

foreach($im->getImageProperties("*") as $k => $v) print("$k: $v<br/>\n");

//export layer
//$im->writeImage('layer_' . $i . '.png'); //导出所有图层到单独的png文件
}
