Examples of sun.awt.image.ByteComponentRaster

sun.awt.image.ByteComponentRaster
This class defines a Raster with pixels consisting of one or more 8-bit data elements stored in close proximity to each other in a single byte array. The bit precision per data element is that of the data type (that is, the bit precision for this Raster is 8). There is only one pixel stride and one scanline stride for all bands. This type of Raster can be used with a ComponentColorModel if there are multiple bands, or an IndexColorModel if there is only one band.
For example, 3-3-2 RGB image data can be represented by a ByteComponentRaster using a SinglePixelPackedSampleModel and a ComponentColorModel.
