Hello and thanks for your work.

However, we can not integrate driver-only feature in imagine. If you want to create such feature, I recommend you to create your own service and apply them using Imagick\Image::getImagick method

By the way there are driver-independent implementation of trim function.
See 4-th message at liip/LiipImagineBundle#586
It has conditional for using Imagick's built-in trimImage function for more performance.

@igormukhingmailcom did you add this at the end?
I resolved my case with listener it works, but it will be nice to have trim filter inside

@antonioperic I used that code (maybe with some small modifications) only on my project and not performed any PR yet.

@igormukhingmailcom thnx for sharing it

[igormukhingmailcom]

@antonioperic I thinking around how to test code right way. Because same fuzz may give different result for native Imagick's and self-writed implementation's output.

I think that should be some source image with linear gradient to test with. And both functions must remove same part of image during trim.

Any update about adding @igormukhingmailcom PR? (well kinda PR)

[antonioperic]

@AlmogBaku I don't think this option will be merged see comment at the begging. But from code you can see how to use it.

@AlmogBaku Hi. That code example can't be added, because it designed to use as extension for LiipImagineBundle at AppBundle. So you can copy-paste it to your AppBundle to use.

(I'm talking about liip/LiipImagineBundle#586)
