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.

    Modifier and Type
    Method
    Description
    void
    dispose()
    Releases the resources allocated for the operation.
    ColorModel
    getColorModel()

    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.
