Example 2 with IntegerInterleavedRaster

use of sun.awt.image.IntegerInterleavedRaster in project jdk8u_jdk by JetBrains.

the class Raster method createPackedRaster.

/**
     * Creates a Raster based on a SinglePixelPackedSampleModel with
     * the specified DataBuffer, width, height, scanline stride, and
     * band masks.  The number of bands is inferred from bandMasks.length.
     * The upper left corner of the Raster is given by
     * the location argument.  If location is null, (0, 0) will be used.
     * @param dataBuffer the <code>DataBuffer</code> that contains the
     *        image data
     * @param w         the width in pixels of the image data
     * @param h         the height in pixels of the image data
     * @param scanlineStride the line stride of the image data
     * @param bandMasks an array containing an entry for each band
     * @param location  the upper-left corner of the <code>Raster</code>
     * @return a WritableRaster object with the specified
     *         <code>DataBuffer</code>, width, height, scanline stride,
     *         and band masks.
     * @throws RasterFormatException if <code>w</code> or <code>h</code>
     *         is less than or equal to zero, or computing either
     *         <code>location.x + w</code> or
     *         <code>location.y + h</code> results in integer
     *         overflow
     * @throws IllegalArgumentException if <code>dataType</code> is not
     *         one of the supported data types, which are
     *         <code>DataBuffer.TYPE_BYTE</code>,
     *         <code>DataBuffer.TYPE_USHORT</code>
     *         or <code>DataBuffer.TYPE_INT</code>
     * @throws RasterFormatException if <code>dataBuffer</code> has more
     *         than one bank.
     * @throws NullPointerException if <code>dataBuffer</code> is null
