Class AbstractTiledRed

java.lang.Object
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 Details

    • 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, Map props)
      Construct an Abstract RenderedImage from a source image, bounds rect 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 ColorModel, SampleModel, and tile grid offsets.
      bounds - The bounds of this image.

    • AbstractTiledRed

      protected AbstractTiledRed(CachableRed src, Rectangle bounds, ColorModel cm, SampleModel sm, Map props)
      Construct an Abstract RenderedImage from a source image, bounds rect and props (may be null).

  • Method Details

    • getDefaultTileSize

      public static int getDefaultTileSize()
    • init

      protected void init(CachableRed src, Rectangle bounds, ColorModel cm, SampleModel sm, int tileGridXOff, int tileGridYOff, 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.
