25 * @test
26 * @bug     8038000 8047066
27 *
28 * @summary Verifies that we could create different type of Rasters with height 1
29 * and strideline which exceeds raster width.
30 * Also checks that a set of RasterOp work correctly with such kind of Rasters.
31 * For 8047066 verifies that ColorConvertOp could process
32 * Raster (ByteBuffer + SinglePixelPackedSampleModel)
