Class AutoLevelsRGB

java.lang.Object

org.broadleafcommerce.openadmin.server.service.artifact.image.effects.chain.filter.BaseFilter

org.broadleafcommerce.openadmin.server.service.artifact.image.effects.chain.filter.AutoLevelsRGB

All Implemented Interfaces:

BufferedImageOp, OperationBuilder

public class AutoLevelsRGB
extends BaseFilter

This filter is based conceptually on the auto-levels feature of Photoshop and functions in the same way. The filter automatically adjusts tonal range for problem photographs, making sure the tones are equally distributed from black to white. Note, a marginal clipping does occur at the highs and lows to account for aberrant pixels in those quadrants that might erroneously effect the calculation.
