  • Method Details

    • create

      public static TiledFileOpImage create(File imageDir, Properties defaultImageProperties) throws IOException
      Throws:
      IOException

    • create

      public static TiledFileOpImage create(VirtualDir imageDir, Properties defaultImageProperties) throws IOException
      Throws:
      IOException

    • create

      public static TiledFileOpImage create(Path imageDir, Properties defaultImageProperties) throws IOException
      Throws:
      IOException

    • computeTile

      public Raster computeTile(int tileX, int tileY)
      Computes a tile. Since the operation has no sources, there is no need to worry about cobbling.

      Subclasses should implement the computeRect(PlanarImage[], WritableRaster, Rectangle) method to perform the actual computation.

      Overrides:
      computeTile in class javax.media.jai.SourcelessOpImage
      Parameters:
      tileX - The X index of the tile.
      tileY - The Y index of the tile.

    • readRawDataTile

      public static void readRawDataTile(ImageInputStream stream, WritableRaster raster) throws IOException
      Reads the data buffer of the given raster from the given image input stream.
      Parameters:
      stream - The image input stream.
      raster - The raster.
      Throws:
      IOException - if an I/O error occurs
      IllegalArgumentException - if the raster's data arrays cannot be retrieved
      NullPointerException - if raster or stream is null

    • writeRawDataTile

      public static void writeRawDataTile(Raster raster, ImageOutputStream stream) throws IOException
      Writes the data buffer of the given raster to the given image output stream.
      Parameters:
      raster - The raster.
      stream - The image output stream.
      Throws:
      IOException - if an I/O error occurs
      IllegalArgumentException - if the raster's data arrays cannot be retrieved
      NullPointerException - if raster or stream is null

    • getDataObject

      public static Object getDataObject(Raster raster)
      Gets the data object from the data buffer of the given raster. The data object which will always be of a primitive array type.
      Parameters:
      raster - The raster.
      Returns:
      The data array.
      Throws:
      IllegalArgumentException - if the raster's data arrays cannot be retrieved
      NullPointerException - if raster is null

    • dispose

      public void dispose()
      Overrides:
      dispose in class javax.media.jai.OpImage
