Constructor Summary | |
public | OverlayOpImage(RenderedImage sourceUnder, RenderedImage sourceOver, Map config, ImageLayout layout) Construct an OverlayOpImage . |
Method Summary | |
protected void | computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect) Copies the pixel values of a source image within a specified
rectangle. | public Raster | computeTile(int tileX, int tileY) Computes a tile. |
OverlayOpImage | public OverlayOpImage(RenderedImage sourceUnder, RenderedImage sourceOver, Map config, ImageLayout layout)(Code) | | Construct an OverlayOpImage .
Parameters: sourceUnder - The source image on the bottom. Parameters: sourceOver - The source image to be overlayed on top ofsourceUnder . Parameters: layout - The image layout for the destination image. |
computeRect | protected void computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)(Code) | | Copies the pixel values of a source image within a specified
rectangle.
Parameters: sources - Cobbled sources, guaranteed to provide all thesource data necessary for computing the rectangle. Parameters: dest - The tile containing the rectangle to be computed. Parameters: destRect - The rectangle within the tile to be computed. |
computeTile | public Raster computeTile(int tileX, int tileY)(Code) | | Computes a tile. This method overrides PointOpImage.computeTile()
Parameters: tileX - The X index of the tile. Parameters: tileY - The Y index of the tile. |
