Fields Summary

Constructors Summary

Methods Summary
public java.awt.image.WritableRaster	copyData(java.awt.image.WritableRaster raster) Computes an arbitrary rectangular region of the RenderedImage and copies it into a caller-supplied WritableRaster. The region to be computed is determined from the bounds of the supplied WritableRaster. The supplied WritableRaster must have a SampleModel that is compatible with this image. If raster is null, an appropriate WritableRaster is created. param raster a WritableRaster to hold the returned portion of the image, or null. return a reference to the supplied or created WritableRaster.
public java.awt.image.ColorModel	getColorModel() Returns the ColorModel associated with this image. All Rasters returned from this image will have this as their ColorModel. This can return null. return the ColorModel of this image.
public java.awt.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). The Raster returned is a copy of the image data and will not be updated if the image is changed. return the image as one large tile.
public java.awt.image.Raster	getData(java.awt.Rectangle rect) Computes and returns an arbitrary region of the RenderedImage. The Raster returned is a copy of the image data and will not be updated if the image is changed. param rect the region of the RenderedImage to be returned. return the region of the RenderedImage indicated by the specified Rectangle.
public int	getHeight() Returns the height of the RenderedImage. return the height of this RenderedImage.
public int	getMinTileX() Returns the minimum tile index in the X direction. return the minimum tile index in the X direction.
public int	getMinTileY() Returns the minimum tile index in the Y direction. return the minimum tile index in the X direction.
public int	getMinX() Returns the minimum X coordinate (inclusive) of the RenderedImage. return the X coordinate of this RenderedImage.
public int	getMinY() Returns the minimum Y coordinate (inclusive) of the RenderedImage. return the Y coordinate of this RenderedImage.
public int	getNumXTiles() Returns the number of tiles in the X direction. return the number of tiles in the X direction.
public int	getNumYTiles() Returns the number of tiles in the Y direction. return the number of tiles in the Y direction.
public java.lang.Object	getProperty(java.lang.String name) Gets a property from the property set of this image. The set of properties and whether it is immutable is determined by the implementing class. This method returns java.awt.Image.UndefinedProperty if the specified property is not defined for this RenderedImage. param name the name of the property return the property indicated by the specified name. see java.awt.Image#UndefinedProperty
public java.lang.String[]	getPropertyNames() Returns an array of names recognized by {@link #getProperty(String) getProperty(String)} or null, if no property names are recognized. return a String array containing all of the property names that getProperty(String) recognizes; or null if no property names are recognized.
public java.awt.image.SampleModel	getSampleModel() Returns the SampleModel associated with this image. All Rasters returned from this image will have this as their SampleModel. return the SampleModel of this image.
public java.util.Vector	getSources() Returns a vector of RenderedImages that are the immediate sources of image data for this RenderedImage. This method returns null if the RenderedImage object has no information about its immediate sources. It returns an empty Vector if the RenderedImage object has no immediate sources. return a Vector of RenderedImage objects.
public java.awt.image.Raster	getTile(int tileX, int tileY) Returns tile (tileX, tileY). Note that tileX and tileY are indices into the tile array, not pixel locations. The Raster that is returned is live and will be updated if the image is changed. param tileX the X index of the requested tile in the tile array param tileY the Y index of the requested tile in the tile array return the tile given the specified indices.
public 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). (Note that tile (0, 0) may not actually exist.) return the X offset of the tile grid relative to the origin.
public 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). (Note that tile (0, 0) may not actually exist.) return the Y offset of the tile grid relative to the origin.
public int	getTileHeight() Returns the tile height in pixels. All tiles must have the same height. return the tile height in pixels.
public int	getTileWidth() Returns the tile width in pixels. All tiles must have the same width. return the tile width in pixels.
public int	getWidth() Returns the width of the RenderedImage. return the width of this RenderedImage.
