Method Detail

getPainter

protected Painter getPainter(ImageContext imageContext,
                             java.util.Dictionary requestedProperties)

Description copied from class: PainterImageRenderer

Returns the Painter to use for the specified request.

Overrides:

getPainter in class PainterImageRenderer

isRenderable

protected boolean isRenderable(ImageContext imageContext,
                               java.util.Dictionary requestedProperties)

Description copied from class: PainterImageRenderer

Tests whether the requested image can be rendered. The default implementation of isRenderable() returns false if oracle.cabo.style.util.GraphicsUtils.isGraphicalEnvironment() returns false. Subclasses can override this to verify that all required properties are present in the requested properties dictionary. All overrides must either call super.isRenderable() or GraphicsUtils.isGraphicalEnvironment() to ensure that a graphical environment is available.

Overrides:

isRenderable in class PainterImageRenderer

createPaintContext

protected PaintContext createPaintContext(ImageContext imageContext,
                                          java.awt.image.BufferedImage image,
                                          java.util.Dictionary requestedProperties,
                                          java.util.Dictionary responseProperties)

Overrides:

                                            java.util.Dictionary d)

Returns the foreground color to use when painting an image with the specified dictionary.

Overrides:
