I have Backend Thumbnail Aspect Ratio (gallery.backend_thumb_far) set to "C" in the system settings and Backend Thumbnail Zoomcrop (gallery.backend_thumb_zoomcrop) set to "yes", but the image thumbnails in the resource browser are zoomed but not cropped, so any image that is not square is all squished. Am I missing something? I've checked, and ImageMagick is installed on my server.
Also, is there a way to set this to letterbox an image rather than crop it so the full image will show up without distortion?
