Examples of java.awt.image.WritableRaster.createWritableTranslatedChild()

java.awt.image.WritableRaster.createWritableTranslatedChild()
Create a WritableRaster with the same size, SampleModel and DataBuffer as this one, but with a different location. The new WritableRaster will possess a reference to the current WritableRaster, accessible through its getParent() and getWritableParent() methods. @param childMinX X coord of the upper left corner of the new Raster. @param childMinY Y coord of the upper left corner of the new Raster. @return a WritableRaster the same as this one exceptfor the specified location. @throws RasterFormatException if computing eitherchildMinX + this.getWidth() or childMinY + this.getHeight() results in integer overflow
