| AbstractRed | | abstract public class AbstractRed implements CachableRed(Code) | | This is an abstract base class that takes care of most of the
normal issues surrounding the implementation of the CachableRed
(RenderedImage) interface. It tries to make no assumptions about
the subclass implementation.

This is one of two basic init function (this is for single
source rendereds).
It is provided so subclasses can compute various values
before initializing all the state in the base class.
You really should call this method before returning from
your subclass constructor.
Parameters:
src - The source for the filter
Parameters:
bounds - The bounds of the image
Parameters:
cm - The ColorModel to use. | | protected void | init(List srcs, Rectangle bounds, ColorModel cm, SampleModel sm, int tileGridXOff, int tileGridYOff, Map props)
This is the basic init function.
It is provided so subclasses can compute various values
before initializing all the state in the base class.
You really should call this method before returning from
your subclass constructor.
Parameters:
srcs - The list of sources
Parameters:
bounds - The bounds of the image
Parameters:
cm - The ColorModel to use. | | public WritableRaster | makeTile(int tileX, int tileY)
This is a helper function that will create the tile requested
Including properly subsetting the bounds of the tile to the
bounds of the current image. | | protected void | updateTileGridInfo()
This function computes all the basic information about the tile
grid based on the data stored in sm, and tileGridX/YOff. |
| minTileXminTileY | | protected int minTileXminTileY(Code) | | |
| numXTilesnumYTiles | | protected int numXTilesnumYTiles(Code) | | |

| tileWidthtileHeight | | protected int tileWidthtileHeight(Code) | | |
| AbstractRed | | protected AbstractRed()(Code) | | void constructor. The subclass must call one of the
flavors of init before the object becomes usable.
This is useful when the proper parameters to the init
method need to be computed in the subclasses constructor.
