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:

cut_contour.png: https://pasteboard.co/GOrgUf2.png
Result with Imagick

Result with GD
