Advanced image custom template variable in MODX Revolution.
With this MODX custom template variable an image could be cropped while maintaining the original image. The dimensions for the image can (optionally) be configured to constrain a minimal width and/or height. The image crop could be forced to remain at a pre-set ratio. A graphical tool could be used to crop the image to the required dimensions/proportions.
