Examples with ShortInterleavedRaster sun.awt.image.ShortInterleavedRaster used on opensource projects

Example 1 with ShortInterleavedRaster

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

the class Raster method createInterleavedRaster.

/**
     * Creates a Raster based on a PixelInterleavedSampleModel with the
     * specified DataBuffer, width, height, scanline stride, pixel
     * stride, and band offsets.  The number of bands is inferred from
     * bandOffsets.length.  The upper left corner of the Raster
     * is given by the location argument.  If location is null, (0, 0)
     * will be used.
     * <p> Note that interleaved <code>DataBuffer.TYPE_INT</code>
     * Rasters are not supported.  To create a 1-band Raster of type
     * <code>DataBuffer.TYPE_INT</code>, use
     * Raster.createPackedRaster().
     * @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 pixelStride the pixel stride of the image data
     * @param bandOffsets the offsets of all bands
     * @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,
     *         pixel stride and band offsets.
     * @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>
     * @throws RasterFormatException if <code>dataBuffer</code> has more
     *         than one bank.
     * @throws NullPointerException if <code>dataBuffer</code> is null
