All Implemented Interfaces:

ImageOperation<ParameterProvider<info.magnolia.cms.core.Content>>

public class SelectedCropAndResize
extends AbstractCropAndResize<ParameterProvider<info.magnolia.cms.core.Content>>

A CropAndResize implementation which uses coordinates as selected in a UI componenent. This currently expects a JSon string representation of CroppingInfo (wrapped in map, which is something that might change...) Given the goo that's Magnolia's current "hiding" of binary nodes, disguising them as properties, it is not possible (?) for a dialog to be configured to store more properties *inside* an image's node; so we resort to 'cropInfoSiblingPropertySuffix': we will look for a property that has the same nade as the ParameterProvider's node, suffixed, and which is a *sibling* of the image's node, not a children.

                         throws ImagingException

Description copied from class: AbstractCropAndResize

Determines the coordinates of the cropping to apply on the source image. If no cropping needs to happen, return new Coords(0, 0, source.getWidth(), source.getHeight()).
