Implements abstract sun.java2d.x11.X11SurfaceData.canSourceSendExposures.

Doc from sun.java2d.x11.X11SurfaceData.canSourceSendExposures.

Returns a boolean indicating whether or not a copyArea from the given rectangle source coordinates might be incomplete and result in X11 GraphicsExposure events being generated from XCopyArea. This method allows the SurfaceData copyArea method to determine if it needs to set the GraphicsExposures attribute of the X11 GC to True or False to receive or avoid the events.

@Override

Overrides sun.java2d.SurfaceData.flush.

Doc from sun.java2d.SurfaceData.flush.

Synchronously releases resources associated with this surface.

@Override

Implements abstract sun.java2d.SurfaceData.getBounds.

Doc from sun.java2d.SurfaceData.getBounds.

Returns the bounds of the destination surface.

@Override

Overrides sun.java2d.SurfaceData.getDefaultScaleX.

Doc from sun.java2d.SurfaceData.getDefaultScaleX.

Returns default horizontal scale factor of the destination surface. Scale factor describes the mapping between virtual and physical coordinates of the SurfaceData. If the scale is 2 then virtual pixel coordinates need to be doubled for physical pixels.

Annotations

@Override

Overrides sun.java2d.SurfaceData.getDefaultScaleY.

Doc from sun.java2d.SurfaceData.getDefaultScaleY.

Returns default vertical scale factor of the destination surface. Scale factor describes the mapping between virtual and physical coordinates of the SurfaceData. If the scale is 2 then virtual pixel coordinates need to be doubled for physical pixels.

Implements abstract sun.java2d.SurfaceData.getReplacement.

Doc from sun.java2d.SurfaceData.getReplacement.

Certain changes in the configuration of a surface require the invalidation of existing associated SurfaceData objects and the creation of brand new ones. These changes include size, ColorModel, or SurfaceType. Existing Graphics objects which are directed at such surfaces, however, must continue to render to them even after the change occurs underneath the covers. The getReplacement() method is called from SunGraphics2D.revalidateAll() when the associated SurfaceData is found to be invalid so that a Graphics object can continue to render to the surface in its new configuration. Such changes only tend to happen to window based surfaces since most image based surfaces never change size or pixel format. Even VolatileImage objects never change size and they only change their pixel format when manually validated against a new GraphicsConfiguration, at which point old Graphics objects are no longer expected to render to them after the validation step. Thus, only window based surfaces really need to deal with this form of replacement.

@Override

Overrides sun.java2d.SurfaceData.getTransparency.

Implements java.awt.Transparency.getTransparency.

Need this since the surface data is created with the color model of the target GC, which is always opaque. But in SunGraphics2D.blitSD we choose loops based on the transparency on the source SD, so it could choose wrong loop (blit instead of blitbg, for example).
