It takes times, but yes it’s working with '-colorspace Gray -solarize 10% -edge 10' for example.
If anyone has the courage to try:
- install kirbyfocuscrop
- replace src/Focus /ImageMagick.php by the file below
- add some <?= $image->focusCrop(500, 500, ['solarize' => true])->url() ?> anywhere
My ImageMagick file :
<?php
