PaintContext (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

java.awt
interface PaintContext

public interface PaintContext

The PaintContext interface defines the encapsulated and optimized environment to generate color patterns in device space for fill or stroke operations on a {@link Graphics2D}. The PaintContext provides the necessary colors for Graphics2D operations in the form of a {@link Raster} associated with a {@link ColorModel}. The PaintContext maintains state for a particular paint operation. In a multi-threaded environment, several contexts can exist simultaneously for a single {@link Paint} object.

Method Summary
`void`	`dispose()` Releases the resources allocated for the operation.
`ColorModel`	`getColorModel()` Returns the `ColorModel` of the output.
`Raster`	`getRaster(int x, int y, int w, int h)` Returns a `Raster` containing the colors generated for the graphics operation.

Method Detail

dispose

public void dispose()

Releases the resources allocated for the operation.

getColorModel

public ColorModel getColorModel()

Returns the ColorModel of the output. Note that this ColorModel might be different from the hint specified in the {@link Paint#createContext(ColorModel, Rectangle, Rectangle2D, AffineTransform, RenderingHints) createContext} method of Paint. Not all PaintContext objects are capable of generating color patterns in an arbitrary ColorModel.

Returns:: the ColorModel of the output.

getRaster

public Raster getRaster(int x,
                        int y,
                        int w,
                        int h)

Returns a Raster containing the colors generated for the graphics operation.

Parameters:: x - the x coordinate of the area in device space for which colors are generated.; y - the y coordinate of the area in device space for which colors are generated.; w - the width of the area in device space; h - the height of the area in device space
Returns:: a Raster representing the specified rectangular area and containing the colors generated for the graphics operation.
