Imagick::mergeImageLayers — Merges image layers
Merges image layers into one. This method is useful when working with image
formats that use multiple layers such as PSD. The merging is controlled using
the layer_method which defines how the layers are merged.
此方法在Imagick基于ImageMagick 6.3.7以上版本编译时可用。
layer_method
One of the Imagick::LAYERMETHOD_* constants
Returns an Imagick object containing the merged image.
错误时抛出 ImagickException。
示例 #1 Imagick::mergeImageLayers()
<?php
function mergeImageLayers($layerMethodType, $imagePath1, $imagePath2) {
$imagick = new \Imagick(realpath($imagePath));
$imagick2 = new \Imagick(realpath($imagePath2));
$imagick->addImage($imagick2);
$imagick->setImageFormat('png');
$result = $imagick->mergeImageLayers($layerMethodType);
header("Content-Type: image/png");
echo $result->getImageBlob();
}
?>
