## 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.

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and 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 Detail

    - #### 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.
