getSelectedImageData

public RenderedImage getSelectedImageData(BufferedImage sourceImage,
 Selection crop,

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.
