This SurfaceManager variant manages the default (software) surface of a BufferedImage. All rendering to the image will use the software surface as the destination. This is one of the more minimalist implementations of SurfaceManager.

Field Summary

public SurfaceData getPrimarySurfaceData()

Implements abstract sun.awt.image.SurfaceManager.getPrimarySurfaceData.

Doc from sun.awt.image.SurfaceManager.getPrimarySurfaceData.

Returns the main SurfaceData object that "owns" the pixels for this SurfaceManager. This SurfaceData is used as the destination surface in a rendering operation and is the most authoritative storage for the current state of the pixels, though other versions might be cached in other locations for efficiency.

public SurfaceData restoreContents()

Implements abstract sun.awt.image.SurfaceManager.restoreContents.

Called from platform-specific SurfaceData objects to attempt to auto-restore the contents of an accelerated surface that has been lost.
