Thank,

I'm also looking for this feature - is it possible to achieve this? Any hints?

@snjegov Hi

Here function that you may use: https://github.com/avalanche123/Imagine/blob/develop/lib/Imagine/Filter/Advanced/Grayscale.php

Or you can write own fast wrapper by yourself.
Here is my example with custom trim filter & wrapper: #586

@mappedinn I am going through all issues to sort and prioritise. Is this still an issue for you? Did garak's solution solve it? Since this is so old, please open a new issue if that is the case and we will prioritise accordingly. Thanks a lot! :)
