Method Summary

Methods
Modifier and Type	Method and Description
`void`	`computeHistogram(java.awt.image.renderable.RenderContext rc)` This method computes the histogram of the image and from that the appropriate clipping points, which leads to a slope and intercept for a LinearTransfer function
`java.awt.image.RenderedImage`	`createRendering(java.awt.image.renderable.RenderContext rc)`
`Filter`	`getSource()` Returns the source of the operation
`float`	`getTrim()` Returns the trim percent for this normalization.
`void`	`setSource(Filter src)` Sets the source of the operation
`void`	`setTrim(float trim)` Sets the trim percent for this normalization.
