Manual crop in Image Transforms I would like to manually crop the image transforms for an uploaded image.

I know there are crop plugins for Craft (image-resizer, AviaryImageEditor), but these plugins crop the original image and not the image transforms.. 

I'm looking for something very similar to the manual crop module in Drupal. 

So you can upload one image, afterwards you manually crop the different image styles / image transforms..

Any suggestions?
I don't know a plugin like this for Craft. But this solution does a similar thing. Maybee it works for you: Let clients set crop position for images. 
Otherwise you could also take a look on the focuspoint plugin: https://github.com/smcyr/Craft-FocusPoint
