 com.sun.media.jai.opimage.PeriodicShiftOpImage
| Constructor Summary | |
| public | PeriodicShiftOpImage(RenderedImage source, Map config, ImageLayout layout, int shiftX, int shiftY)
Creates a OpImage to return the tiles of a periodic extension. |
| Method Summary | |
| public Raster | computeTile(int tileX, int tileY)
Computes a tile of the destination by copying the data which
overlaps the tile in the four translated source images. | | 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. |
| PeriodicShiftOpImage | | public PeriodicShiftOpImage(RenderedImage source, Map config, ImageLayout layout, int shiftX, int shiftY)(Code) | | Creates a OpImage to return the tiles of a periodic extension.
Parameters:
source - a RenderedImage.
Parameters:
layout - an ImageLayout optionally containing the tile gridlayout, SampleModel, and ColorModel, or null.
Parameters:
shiftX - the number of pixels of horizontal translation.
Parameters:
shiftY - the number of pixels of vertical translation. |
| computeTile | | public Raster computeTile(int tileX, int tileY)(Code) | | Computes a tile of the destination by copying the data which
overlaps the tile in the four translated source images.
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. |
