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
