# 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 `Graphics2D`. The `PaintContext` provides the necessary colors for `Graphics2D` operations in the form of a `Raster` associated with a `ColorModel`. The `PaintContext` maintains state for a particular paint operation. In a multi-threaded environment, several contexts can exist simultaneously for a single `Paint` object.

## Method Summary

Modifier and Type
Method
Description
`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 Details

### dispose

void dispose()
Releases the resources allocated for the operation.

### getColorModel

ColorModel getColorModel()
Returns the `ColorModel` of the output. Note that this `ColorModel` might be different from the hint specified in the `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

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.
