Description
RenderedImage is a common interface for objects which contain
or can produce image data in the form of Rasters.
Methods
public WritableRaster
copyData
(WritableRaster raster)
Computes an arbitrary rectangular region of the RenderedImage
and copies it into a caller-supplied WritableRaster.
public 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).
public Raster
getData
(Rectangle rect)
Computes and returns an arbitrary region of the RenderedImage.
public int
getHeight
()
Returns the height of the RenderedImage.
public int
getMinTileX
()
Returns the minimum tile index in the X direction.
public int
getMinTileY
()
Returns the minimum tile index in the Y direction.
public int
getMinX
()
Returns the minimum X coordinate (inclusive) of the RenderedImage.
public int
getMinY
()
Returns the minimum Y coordinate (inclusive) of the RenderedImage.
public int
getNumXTiles
()
Returns the number of tiles in the X direction.
public int
getNumYTiles
()
Returns the number of tiles in the Y direction.
public String
getPropertyNames
()
Returns an array of names recognized by
getProperty(String)
or null, if no property names are recognized.
public Vector<RenderedImage>
getSources
()
Returns a vector of RenderedImages that are the immediate sources of
image data for this RenderedImage.
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).
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).
public int
getTileHeight
()
Returns the tile height in pixels.
public int
getTileWidth
()
Returns the tile width in pixels.
public int
getWidth
()
Returns the width of the RenderedImage.
