将Java2D保存到SWF(闪存)

Question

我正在尝试将Java2D中矢量图像drawin的输出保存到SWF文件中.有很多用于保存java2D输出的库,如SVG(BATIK)和PDF(itext),但我找不到一个用于SWF.有任何想法吗？

Answer 1

我刚刚得到一个使用Adobe Flex 3中的SpriteGraphics2D对象的示例.仅供参考...... Flex 3现在是开源的.

(来自SpriteGraphics2D javadoc) SpriteGraphics2D是Java2D的Graphics2D API的SWF特定实现.对此类的调用将转换为可用于构造SWF Sprite的TagList.

我通过查看CubicCurveTest.java和SpriteTranscoder.java这两个类来解决这个问题.

运行此示例所需的两个罐子是swfutils.jar和batik-awt-util.jar,可以在这里下载.

这是我的示例代码......

     // Create the SpriteGraphics2D object
     SpriteGraphics2D g = new SpriteGraphics2D(100, 100);

     // Draw on to the graphics object
     Font font = new Font("Serif", Font.PLAIN, 16);
     g.setFont(font);         
     g.drawString("Test swf", 30, 30);         
     g.draw(new Line2D.Double(5, 5, 50, 60));
     g.draw(new Line2D.Double(50, 60, 150, 40));
     g.draw(new Line2D.Double(150, 40, 160, 10));

     // Create a new empty movie
     Movie m = new Movie();
     m.version = 7;
     m.bgcolor = new SetBackgroundColor(SwfUtils.colorToInt(255, 255, 255));
     m.framerate = 12;
     m.frames = new ArrayList(1);
     m.frames.add(new Frame());
     m.size = new Rect(11000, 8000);

     // Get the DefineSprite from the graphics object
     DefineSprite tag = g.defineSprite("swf-test");

     // Place the DefineSprite on the first frame
     Frame frame1 = (Frame) m.frames.get(0);
     Matrix mt = new Matrix(0, 0);
     frame1.controlTags.add(new PlaceObject(mt, tag, 1, null));

     TagEncoder tagEncoder = new TagEncoder();
     MovieEncoder movieEncoder = new MovieEncoder(tagEncoder);
     movieEncoder.export(m);

     //Write to file
     FileOutputStream fos = new FileOutputStream(new File("/test.swf"));
     tagEncoder.writeTo(fos);
