imagemagick叠图

请问怎么用imagemagick库实现GD库中imagecopyresampled的功能？把两张图叠在一起，看英文文档快看吐了，求捷径，哪怕告诉一个方法名我自己去研究，多谢！

回复讨论(解决方案)

//打开文件$imgA = "phpcn_logo.gif";$imgB = "phpchina.gif";$sourceImg = imagecreatefromgif($imgA);$targetImg = imagecreatefromgif($imgB);//获取文件大小$sourceSize = getimagesize($imgA);$targetSize = getimagesize($imgB);//合并图片imagecopyresized($targetImg, $sourceImg, 0, 0, 0, 0, $targetSize[0], $targetSize[1], $sourceSize[0], $sourceSize[1]);//保存结果$r = imagegif($targetImg, "c.gif");if($r){        echo "成功";}else{        echo "失败";}

已经实现，文档看吐了，贴代码啥也不说了

$image = new Imagick('05.png');$imagepng = new Imagick('16.png');$imagepng->setImageFormat("png");$image->compositeImage($imagepng, $imagepng->getImageCompose(), 0, 0);$imagepng->destroy();header("Content-Type: image/png");echo $image;$image->destroy();

直接用imagick。

$cmd = sprintf("composite -gravity %s -geometry %s -dissolve %s '%s' %s %s", 'SouthEast', '+10+10', 100, '16.png', '05.png', '05.png');  exec($cmd);
