org.apache.batik.ext.awt.image.rendered.AbstractRed

org.apache.batik.ext.awt.image.rendered.AbstractTiledRed

All Implemented Interfaces:

RenderedImage, CachableRed, TileGenerator

Direct Known Subclasses:

SpecularLightingRed, TileCacheRed

public abstract class AbstractTiledRed
extends AbstractRed
implements TileGenerator

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.

Constructor Detail

AbstractTiledRed

protected AbstractTiledRed()

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.

AbstractTiledRed

protected AbstractTiledRed(Rectangle bounds,
                Map props)

Construct an Abstract RenderedImage from a bounds rect and props (may be null). The srcs Vector will be empty.

Parameters:

bounds - this defines the extent of the rable in the user coordinate system.

props - this initializes the props Map (may be null)

AbstractTiledRed

protected AbstractTiledRed(CachableRed src,
                Map props)

Construct an Abstract RenderedImage from a source image and props (may be null).

Parameters:

src - will be the first (and only) member of the srcs Vector. Src is also used to set the bounds, ColorModel, SampleModel, and tile grid offsets.

props - this initializes the props Map.

AbstractTiledRed

protected AbstractTiledRed(CachableRed src,
                Rectangle bounds,

Parameters:

src - will be the first (and only) member of the srcs Vector. Src is also used to set the ColorModel, SampleModel, and tile grid offsets.

        Map props)

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.

Overrides:

init in class AbstractRed

Parameters:

src - The source for the filter

bounds - The bounds of the image

cm - The ColorModel to use. If null it defaults to ComponentColorModel/ src's ColorModel.

sm - The Sample modle to use. If this is null it will use the src's sample model if that is null it will construct a sample model that matches the ColorModel and is the size of the whole image.

tileGridXOff - The x location of tile 0,0.

tileGridYOff - The y location of tile 0,0.

props - Any properties you want to associate with the image.
