Examples of java.awt.image.IndexColorModel.convertToIntDiscrete()

java.awt.image.IndexColorModel.convertToIntDiscrete()
Returns a new BufferedImage of TYPE_INT_ARGB or TYPE_INT_RGB that has a Raster with pixel data computed by expanding the indices in the source Raster using the color/alpha component arrays of this ColorModel. Only the lower n bits of each index value in the source Raster, as specified in the class description above, are used to compute the color/alpha values in the returned image. If forceARGB is true, a TYPE_INT_ARGB image is returned regardless of whether or not this ColorModel has an alpha component array or a transparent pixel. @param raster the specified Raster @param forceARGB if true, the returned BufferedImage is TYPE_INT_ARGB; otherwise it is TYPE_INT_RGB @return a BufferedImage created with the specifiedRaster @throws IllegalArgumentException if the raster argument is notcompatible with this IndexColorModel
