Class AutoCropAndResize

      info.magnolia.imaging.operations.cropresize.AutoCropAndResize

All Implemented Interfaces:

ImageOperation

public class AutoCropAndResize
extends AbstractCropAndResize

A CropAndResize implementation which will resize to the configured targetWidth and targetHeight, and crop if needed: while respecting the ratio of the target dimensions, it will crop the image such that the largest possible portion of the image is kept. It will keep the central part of the image and cut off the external parts. (i.e centered crop) If either targetWidth or targetHeight is <=0, the ratio of the source image will be preserved. If both targetWidth and targetHeight are >0, both will be used, even if they don't match the ratio of the source image (thus cropping it).

getCroopCoords

protected Coords getCroopCoords(BufferedImage source,
                                ParameterProvider params)
                         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()).
