org.gvsig.raster.impl.grid.filter.FilterLoaderImpl

All Implemented Interfaces:

FilterLoader

public class FilterLoaderImpl
extends java.lang.Object
implements FilterLoader

Applies the stack of filters to a buffer. With the same FilterLoader you can process different buffers. Each buffer can use a different environment

Method Detail

addTransparency

public void addTransparency(Transparency transparency)

Specified by:

addTransparency in interface FilterLoader

addSrcDataType

public void addSrcDataType(int datatype)

Specified by:

addSrcDataType in interface FilterLoader

addSrcBandCount

public void addSrcBandCount(int bandcount)

Specified by:

addSrcBandCount in interface FilterLoader

addSrcStatistics

public void addSrcStatistics(Statistics statistics)

Specified by:

addSrcStatistics in interface FilterLoader

addSrcROI

public void addSrcROI(java.util.List<ROI> roi)

Specified by:

addSrcROI in interface FilterLoader

addSrcHistogram

public void addSrcHistogram(HistogramComputer histogram)

Specified by:

addSrcHistogram in interface FilterLoader

applyFilters

public Buffer applyFilters(Buffer buffer)

Specified by:

applyFilters in interface FilterLoader

getTransparency

public Transparency getTransparency()

Description copied from interface: FilterLoader

Gets the transparency object and the color interpretation of the result. Mostly, filters returns ARGB images but sometimes the filter can modify the transparency configuration and the color interpretation. For instance, when a color table is applied or a alpha band is added by the filter.

Specified by:

getTransparency in interface FilterLoader

Returns:

getBufferResult

public Buffer getBufferResult()

Description copied from interface: FilterLoader

Gets the buffer result after the function applyFilters is executed. If the buffer has not been modified, it will return the input buffer.

Specified by:

getBufferResult in interface FilterLoader

Returns:
