Is there support for multiple processors?

[ghost]

I love how the minimagick lib works, but one other thing I would maybe like to do is process the image through ImageOptim for example... but it seems I would have to fork the minimagick lib to do that?

Also, is there a way to control the compression of an uploaded jpg for example?

You don't have to fork it, you can simply call the Refile::MiniMagick methods from your own processor.

@jnicklas could you give an example on how to do this? By that i mean how do i add a process by default when i call the helper like so: <%= attachment_url(@cover, :thumbnail, :fill, 1920, 1080) %>
