Description

I notice some weird dark borders applying mask using Imagick.
Using GD, mask is very slow but borders seems ok.

Thought?

This is the code:
$image = Image::make('image.png');
$cutContour = Image::make('cut_contour.png');

$image->mask($cutContour, true);

return $image->response();
These are the original images:

Research direction

Start by reproducing the provided Image::make and mask example with the Imagick and GD drivers, using the linked source images. Compare the resulting borders and trace the mask operation to identify the driver-specific behavior; done means the discrepancy is reproduced and its cause or a narrowly defined fix is established.
