Method Detail

setSource

public void setSource(Filter src)

Sets the source of the operation

Specified by:

setSource in interface BatikHistogramNormalizationFilter

Parameters:

src - image to offset.

getSource

public Filter getSource()

Returns the source of the operation

Specified by:

getSource in interface BatikHistogramNormalizationFilter

getTrim

public float getTrim()

Returns the trim percent for this normalization.

Specified by:

getTrim in interface BatikHistogramNormalizationFilter

setTrim

public void setTrim(float trim)

Sets the trim percent for this normalization.

Specified by:

setTrim in interface BatikHistogramNormalizationFilter

computeHistogram

public 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

Parameters:

rc - We get the set of rendering hints from rc.

createRendering

public java.awt.image.RenderedImage createRendering(java.awt.image.renderable.RenderContext rc)

Specified by:

createRendering in interface java.awt.image.renderable.RenderableImage
