 com.sun.media.jai.opimage.TranslateIntOpImage
| TranslateIntOpImage | | final public class TranslateIntOpImage extends OpImage (Code) | | An OpImage to translate an image by in integral number of pixels.
The translation is accomplished by simply shifting the tile
grid.
|
| Constructor Summary | |
| public | TranslateIntOpImage(RenderedImage source, Map config, int transX, int transY)
Construct an TranslateIntOpImage. |
| Method Summary | |
| public Raster | computeTile(int tileX, int tileY)
Override computeTile() simply to invoke getTile(). | | public boolean | computesUniqueTiles()
Returns false as computeTile() invocations
return child Rasters of the RenderedImage
source and are therefore not unique objects in the global sense. | | public Raster | getTile(int tileX, int tileY)
Get a tile. | | public Rectangle | mapDestRect(Rectangle destRect, int sourceIndex)
Returns a conservative estimate of the region of a specified
source that is required in order to compute the pixels of a
given destination rectangle.
Parameters:
destRect - the Rectangle in destination coordinates.
Parameters:
sourceIndex - the index of the source image. | | public Rectangle | mapSourceRect(Rectangle sourceRect, int sourceIndex)
Returns a conservative estimate of the destination region that
can potentially be affected by the pixels of a rectangle of a
given source.
Parameters:
sourceRect - the Rectangle in source coordinates.
Parameters:
sourceIndex - the index of the source image. |
| TranslateIntOpImage | | public TranslateIntOpImage(RenderedImage source, Map config, int transX, int transY)(Code) | | Construct an TranslateIntOpImage.
Parameters:
source - a RenderedImage.
Parameters:
config - Configurable attributes of the image includingconfiguration variables indexed byRenderingHints.Keys and image properties indexedby Strings or CaselessStringKeys.This is simply forwarded to the superclass constructor.
Parameters:
transX - the number of pixels of horizontal translation.
Parameters:
transY - the number of pixels of vertical translation. |
| computeTile | | public Raster computeTile(int tileX, int tileY)(Code) | | Override computeTile() simply to invoke getTile(). Required
so that the TileScheduler may invoke computeTile().
|
| computesUniqueTiles | | public boolean computesUniqueTiles()(Code) | | Returns false as computeTile() invocations
return child Rasters of the RenderedImage
source and are therefore not unique objects in the global sense.
|
| getTile | | public Raster getTile(int tileX, int tileY)(Code) | | Get a tile.
Parameters:
tileX - The X index of the tile.
Parameters:
tileY - The Y index of the tile. |
| mapDestRect | | public Rectangle mapDestRect(Rectangle destRect, int sourceIndex)(Code) | | Returns a conservative estimate of the region of a specified
source that is required in order to compute the pixels of a
given destination rectangle.
Parameters:
destRect - the Rectangle in destination coordinates.
Parameters:
sourceIndex - the index of the source image. a Rectangle indicating the required source region.
throws:
IllegalArgumentException - if the source index isnegative or greater than that of the last source.
throws:
IllegalArgumentException - if destRect is null. |
| mapSourceRect | | public Rectangle mapSourceRect(Rectangle sourceRect, int sourceIndex)(Code) | | Returns a conservative estimate of the destination region that
can potentially be affected by the pixels of a rectangle of a
given source.
Parameters:
sourceRect - the Rectangle in source coordinates.
Parameters:
sourceIndex - the index of the source image. a Rectangle indicating the potentially affecteddestination region. or null if the region is unknown.
throws:
IllegalArgumentException - if the source index isnegative or greater than that of the last source.
throws:
IllegalArgumentException - if sourceRect is null. |
