I've got some images that are not square (portrait and landscape format), but I want them cropped square with CE Image.

I've tried various parameters from the documentation, but the results are stretched unnaturally. I'd prefer to have the image cropped to center and not scaled.

{exp:ce_img:single src="{image}" filter="grayscale" filename_suffix="-OFF" unique="none" class="fadein" max="192" crop="yes|center,center|0,0|no"}
