BatikHistogramNormalizationFilter8Bit

public BatikHistogramNormalizationFilter8Bit(Filter src,
                                             float trim)
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(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 RenderedImage createRendering(RenderContext rc)
Specified by:
createRendering in interface RenderableImage
