From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- libjava/classpath/gnu/java/awt/AWTUtilities.java | 898 ++++++++ libjava/classpath/gnu/java/awt/BitMaskExtent.java

  1. If the font has a type 4 cmap for the Unicode platform + * (encoding 0, 1, 2, 3 or 4), or a type 4 cmap for the Microsoft + * platform (encodings 1 or 10), that table is used to map Unicode + * codepoints to glyphs. Most recent fonts, both for Macintosh and + * Windows, should provide such a table.
    2. + * + *
  2. Otherwise, if the font has any type 0 cmap for the Macintosh + * platform, a Unicode-to-glyph mapping is synthesized from certain + * type 0 cmaps. The current implementation collects mappings from + * Roman, Icelandic, Turkish, Croatian, Romanian, Eastern European, + * Cyrillic, Greek, Hebrew, Arabic and Farsi cmaps.

Lack of Thread Safety: The virtual machine is + * intentionally not safe to access from multiple concurrent + * threads. Synchronization needs to be performed externally. Usually, + * the font has already obtained a lock before calling the scaler, + * which in turn calls the VM. It would be wasteful to acquire + * additional locks for the VM. + * + *

Implementation Status: The current implementation can + * execute pre-programs of fonts, but it does not yet actually move + * any points. Control flow and arithmeti instructions are + * implemented, but most geometric instructions are not working + * yet. So, the VirtualMachine class is currently a no-op. However, + * not very much is missing. You are more than welcome to complete the + * implementation. + * + *

Patents: Apple Computer holds three United States Patents + * for the mathematical algorithms that are used by TrueType + * instructions. The monopoly granted by these patents will expire in + * October 2009. Before the expiration date, a license must be + * obtained from Apple Computer to use the patented technology inside + * the United States. For other countries, different dates might + * apply, or no license might be needed. + * + *

The default build of this class does not use the patented + * algorithms. If you have obtained a license from Apple, or if the + * patent protection has expired, or if no license is required for + * your contry, you can set a flag in the source file which will + * enable the use of the patented mathematical algorithms.

It is + * meant as a base class for Graphics2D implementations. + * + *

Backend interface

+ *

+ * The backend must at the very least provide a Raster which the the rendering + * pipeline can paint into. This must be implemented in + * {@link #getDestinationRaster()}. For some backends that might be enough, like + * when the target surface can be directly access via the raster (like in + * BufferedImages). Other targets need some way to synchronize the raster with + * the surface, which can be achieved by implementing the + * {@link #updateRaster(Raster, int, int, int, int)} method, which always gets + * called after a chunk of data got painted into the raster. + *

+ *

Alternativly the backend can provide a method for filling Shapes by + * overriding the protected method fillShape(). This can be accomplished + * by a polygon filling function of the backend. Keep in mind though that + * Shapes can be quite complex (i.e. non-convex and containing holes, etc) + * which is not supported by all polygon fillers. Also it must be noted + * that fillShape() is expected to handle painting and compositing as well as + * clipping and transformation. If your backend can't support this natively, + * then you can fallback to the implementation in this class. You'll need + * to provide a writable Raster then, see above.

+ *

Another alternative is to implement fillScanline() which only requires + * the backend to be able to draw horizontal lines in device space, + * which is usually very cheap. + * The implementation should still handle painting and compositing, + * but no more clipping and transformation is required by the backend.

+ *

The backend is free to provide implementations for the various raw* + * methods for optimized AWT 1.1 style painting of some primitives. This should + * accelerate painting of Swing greatly. When doing so, the backend must also + * keep track of the clip and translation, probably by overriding + * some clip and translate methods. Don't forget to message super in such a + * case.

+ * + *

Acceleration options

+ *

+ * The fact that it is + * pure Java makes it a little slow. However, there are several ways of + * accelerating the rendering pipeline: + *

    + *
  1. Optimization hooks for AWT 1.1 - like graphics operations. + * The most important methods from the {@link java.awt.Graphics} class + * have a corresponding raw* method, which get called when + * several optimization conditions are fullfilled. These conditions are + * described below. Subclasses can override these methods and delegate + * it directly to a native backend.
    2. + *
  2. Native PaintContexts and CompositeContext. The implementations + * for the 3 PaintContexts and AlphaCompositeContext can be accelerated + * using native code. These have proved to two of the most performance + * critical points in the rendering pipeline and cannot really be done quickly + * in plain Java because they involve lots of shuffling around with large + * arrays. In fact, you really would want to let the graphics card to the + * work, they are made for this.
    3. + *
  3. Provide an accelerated implementation for fillShape(). For instance, + * OpenGL can fill shapes very efficiently. There are some considerations + * to be made though, see above for details.

Swing based AWT peers.

+

This package defines an abstract set of AWT peers that is based on Swing + widgets. This can be used as an implementation base for peer implementors + who don't have access to native widgets or who want to build a quick + prototype of a peer set without implementing all of the AWT widgets. +

+

An actual implementation would have to provide the following: +

    +
  • A concrete implementation of {@link java.awt.Toolkit}, possibly based + on {@link SwingToolkit}. This implementation must provide all the missing + methods of the SwingToolkit.
    • +
  • Concrete implementations of {@link java.awt.peer.DialogPeer}, + {@link java.awt.peer.FramePeer} and {@link java.awt.peer.WindowPeer}, + ideally based on their SwingXXXPeer counterparts. + Some methods must be specially + overridden in those peers to provide useful functionality, like + getLocationOnScreen(). See the API documentation for more + details
    • +
  • An implementation of {@link java.awt.Image}. These must be provided by + the toplevel component peers.
    • +
  • An implementation of {@link java.awt.Graphics}. This must also be + provided by the toplevel peers.
    • +
  • An implementation of {@link java.awt.Font}. This must be + provided by the toolkit.
