static Raster |
Raster.createRaster(SampleModel sm,
DataBuffer db,
Point location)
Creates a Raster with the specified SampleModel and DataBuffer.
|
|
Raster |
Raster.createTranslatedChild(int childMinX,

|---|---|---|
BufferedImage |
IndexColorModel.convertToIntDiscrete(Raster raster,
boolean forceARGB)
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. |
