public class WritableRaster

extends Raster

This class extends Raster to provide pixel writing capabilities. Refer to the class comment for Raster for descriptions of how a Raster stores pixels.

The constructors of this class are protected. To instantiate a WritableRaster, use one of the createWritableRaster factory methods in the Raster class.

Method Summary
WritableRaster	createWritableChild(int parentX, int parentY, int w, int h, int childMinX, int childMinY, int[] bandList)     Returns a new WritableRaster which shares all or part of this WritableRaster's DataBuffer.
WritableRaster	createWritableTranslatedChild(int childMinX, int childMinY)     Create a WritableRaster with the same size, SampleModel and DataBuffer as this one, but with a different location.
WritableRaster	getWritableParent()     Returns the parent WritableRaster (if any) of this WritableRaster, or else null.
void	setDataElements(int x, int y, int w, int h, Object inData)     Sets the data for a rectangle of pixels from a primitive array of type TransferType.
void	setDataElements(int x, int y, Object inData)     Sets the data for a single pixel from a primitive array of type TransferType.
void	setDataElements(int x, int y, Raster inRaster)     Sets the data for a rectangle of pixels from an input Raster.
void	setPixel(int x, int y, double[] dArray)     Sets a pixel in the DataBuffer using a double array of samples for input.
void	setPixel(int x, int y, float[] fArray)     Sets a pixel in the DataBuffer using a float array of samples for input.
void	setPixel(int x, int y, int[] iArray)     Sets a pixel in the DataBuffer using an int array of samples for input.
void	setPixels(int x, int y, int w, int h, double[] dArray)     Sets all samples for a rectangle of pixels from a double array containing one sample per array element.
void	setPixels(int x, int y, int w, int h, float[] fArray)     Sets all samples for a rectangle of pixels from a float array containing one sample per array element.
void	setPixels(int x, int y, int w, int h, int[] iArray)     Sets all samples for a rectangle of pixels from an int array containing one sample per array element.
void	setRect(int dx, int dy, Raster srcRaster)     Copies pixels from Raster srcRaster to this WritableRaster.
void	setRect(Raster srcRaster)     Copies pixels from Raster srcRaster to this WritableRaster.
void	setSample(int x, int y, int b, double s)     Sets a sample in the specified band for the pixel located at (x,y) in the DataBuffer using a double for input.
void	setSample(int x, int y, int b, float s)     Sets a sample in the specified band for the pixel located at (x,y) in the DataBuffer using a float for input.
void	setSample(int x, int y, int b, int s)     Sets a sample in the specified band for the pixel located at (x,y) in the DataBuffer using an int for input.
void	setSamples(int x, int y, int w, int h, int b, double[] dArray)     Sets the samples in the specified band for the specified rectangle of pixels from a double array containing one sample per array element.
