getSelectedImageData

public RenderedImage getSelectedImageData(BufferedImage sourceImage,
                                          Selection crop,
                                          int size)

Creates an image consisting of the given selection of the source image rescaled to a square with the given size. If the selection is null, a not-entirely-stupid algorithm for determining a plausible square subselection.

Parameters:

sourceImage - the image source to crop and scale from.

crop - the subrectangle to use, usually square to avoid aspect ratio changes.

size - the desired size of the edge of the resulting square image.

Returns:

the new image.
