Method Detail

createComponentColorModel

public static java.awt.image.ColorModel createComponentColorModel(java.awt.image.SampleModel sm)

A convenience method to create an instance of ComponentColorModel suitable for use with the given SampleModel. The SampleModel should have a data type of DataBuffer.TYPE_BYTE, TYPE_USHORT, or TYPE_INT and between 1 and 4 bands. Depending on the number of bands of the SampleModel, either a gray, gray+alpha, rgb, or rgb+alpha ColorModel is returned.

copyData

public java.awt.image.WritableRaster copyData(java.awt.image.WritableRaster wr)

getTile

public java.awt.image.Raster getTile(int tileX,
                                     int tileY)

Overrides:

getTile in class AbstractRed
