[magick-users] Square thumbnails

[Noel da Costa]

Hi John,

Thanks for the reply.
I'm performing a crop, rather than a change of proportion.

Here's the actual convert command being run:

convert -geometry 70x70 /assets/thumbnails/20.jpg  -background white - 
flatten -transparent white -thumbnail x140 -resize '140x<' -resize  
50% -gravity center -crop 70x70+0+0 +repage /assets/thumbnails/20.jpg


Thanks,
Noel
