* Fixed Issue 278: Fatal error when rendering text Kenneth Russel2007-02-271-1/+2
| | | | | | | | | Added code to restore current text drawing color when backing store is resized. Fixed NullPointerException in RectanglePacker during deletion if no backing store was allocated. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1156 232f8b59-042b-4e1e-8c03-345bb8c30851
* Robustness improvements to TextRenderer and underlying RectanglePacker. Kenneth Russel2007-01-134-58/+256
| | | | | | | | | | | | | | | Added ability to specify a maximum size to which the RectanglePacker can expand. Added preExpand method to BackingStoreManager to support early eviction of unused entries instead of always expanding the backing store, and additionFailed method used when the backing store can not expand further. Added more robust free list coalescing to Level. Added support for shrinking of backing store and for eager compaction when there is a lot of vertical dead space. Added TextFlow demo which shows how to do dynamic layout of text and which acts as a stress test for the TextRenderer. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1083 232f8b59-042b-4e1e-8c03-345bb8c30851
* With extensive help from Phil Race and Chris Campbell from the Java 2D Kenneth Russel2007-01-047-0/+893
team, added a TextRenderer class which enables high-performance rendering of bitmapped Java 2D fonts, with full Unicode support, into arbitrary OpenGL drawables using a simple API. Builds on top of the TextureRenderer class and its associated functionality; added createAlphaOnlyRenderer() and other methods to enable the TextRenderer. Caches rendering results on a string-by-string basis in an OpenGL texture using a fully automatic least-recently-used algorithm for good efficiency when rendering the same string or strings multiple times. Uses a rectangle packing algorithm, currently housed in com.sun.opengl.impl.packrect, for managing the positions of cached strings on a larger OpenGL texture to avoid OpenGL pipeline state changes. Added a TestTextRenderer demo which simply adds a moving text string and frames-per-second counter to the Gears demo; more sophisticated examples to come. (Some commented-out debugging code is being temporarily left in the new demo, to be removed in the next checkin, in order to have it in the version history.) git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1067 232f8b59-042b-4e1e-8c03-345bb8c30851
