Examples of java.awt.image.RenderedImage.copyData()

java.awt.image.RenderedImage.copyData()
Computes an arbitrary rectangular region of the RenderedImage and copies it into a caller-supplied WritableRaster. The region to be computed is determined from the bounds of the supplied WritableRaster. The supplied WritableRaster must have a SampleModel that is compatible with this image. If raster is null, an appropriate WritableRaster is created. @param raster a WritableRaster to hold the returned portion of theimage, or null. @return a reference to the supplied or created WritableRaster.

        BufferedImage bi = new BufferedImage(ri.getColorModel(), ri.copyData(null), false, new Hashtable());
        ss.close();
        return bi;
