RenderedImage is a common interface for objects which contain or can produce image data in the form of Rasters. The image data may be stored/produced as a single tile or a regular array of tiles.
Method Summary | |
WritableRaster |
copyData(WritableRaster raster)
Computes an arbitrary rectangular region of the RenderedImage and copies it into a caller-supplied WritableRaster. |
ColorModel |
getColorModel()
Returns the ColorModel associated with this image. |
Raster |
getData()
Returns the image as one large tile (for tile based images this will require fetching the whole image and copying the image data over). |
Raster |
getData(Rectangle rect)
Computes and returns an arbitrary region of the RenderedImage. |
int |
getHeight()
Returns the height of the RenderedImage. |
int |
getMinTileX()
Returns the minimum tile index in the X direction. |
int |
getMinTileY()
Returns the minimum tile index in the Y direction. |
int |
getMinX()
Returns the minimum X coordinate (inclusive) of the RenderedImage. |
int |
getMinY()
Returns the minimum Y coordinate (inclusive) of the RenderedImage. |
int |
getNumXTiles()
Returns the number of tiles in the X direction. |
int |
getNumYTiles()
Returns the number of tiles in the Y direction. |
Object |
getProperty(String name)
Gets a property from the property set of this image. |
String[] |
getPropertyNames()
Returns an array of names recognized by getProperty(String)
or null , if no property names are recognized. |
SampleModel |
getSampleModel()
Returns the SampleModel associated with this image. |
Vector |
getSources()
Returns a vector of RenderedImages that are the immediate sources of image data for this RenderedImage. |
Raster |
getTile(int tileX,
int tileY)
Returns tile (tileX, tileY). |
int |
getTileGridXOffset()
Returns the X offset of the tile grid relative to the origin, i.e., the X coordinate of the upper-left pixel of tile (0, 0). |
int |
getTileGridYOffset()
Returns the Y offset of the tile grid relative to the origin, i.e., the Y coordinate of the upper-left pixel of tile (0, 0). |
int |
getTileHeight()
Returns the tile height in pixels. |
int |
getTileWidth()
Returns the tile width in pixels. |
int |
getWidth()
Returns the width of the RenderedImage. |
