Imagick::clipPathImage — Clips along the named paths from the 8BIM profile
$pathname
, bool $inside
)Clips along the named paths from the 8BIM profile, if present. Later operations take effect inside the path. It may be a number if preceded with #, to work on a numbered path, e.g., "#1" to use the first path.
pathname
The name of the path
inside
If TRUE
later operations take effect inside clipping path.
Otherwise later operations take effect outside clipping path.
成功时返回 TRUE

I found Imagick::clipPathImage and Imagic::clipImage did not work as I had expected. I thought they would just clip the path and throw away the extra data and you are done. Not the case.
Here is how I was able to use a clipping path:
<?php
$img = new Imagick("/Path/To/Test/Image.psd");
$geometry = $img->getImageGeometry();
// Uses the first path as the clipping path
$img->clipPathImage("#1", false);
// Fill the clipped part with a color
$draw = new ImagickDraw();
$draw->setFillColor("#000000");
$draw->color(0,0, imagick::PAINT_RESET);
$img->drawImage($draw);
// Composite the clipped image with the old image. Set the color of the composite to any color you want to be the outside part.
$composite = new Imagick($path);
$composite->newImage( $geometry['width'], $geometry['height'], new ImagickPixel("white"), 'png');
$composite->compositeImage($img, imagick::COMPOSITE_COPY, 0, 0);
?>
Then doing any resizing or creating thumbnails from the resulting image disregarded all the previous commands so I "saved" it and started with a new Imagick object
<?php
// Copy the image so clip is "saved"
$clipped = new Imagick();
$clipped->readImageBlob($composite->getImageBlob());
?>
I'm sure there is a simpler way, but this took me awhile to get right and there were some hurdles to cross so I hope it is able to help someone on the way.
This is all the convert equivalent of:
$ convert Test.psd -fill white -colorspace rgb -draw "color 0 0 reset" -clip -colorspace rgb -draw "Image Copy 0,0 0,0 'Test.psd'" OutputFile.png
