There are still many things to do until I release version 0.1, of course. For now, only null layout is supported. Support for other layout managers will be added in the future. The goal is to be able to translate all windows created by Matisse as long as they use the supported layout managers. As expected, there will be no support for widgets that wxWidgets offers for an operating system exclusively. Unlike Matisse, you will have total freedom to modify the generated code, as there is no coming back from it. The windows that wxMatisse translates need not be created by Matisse: as this translator uses the properties of the window rather than code, it does not rely on any code convention. As long as the code compiles and runs, the code can be a complete mess that wxMatisse will still work. wxMatisse will be useful for migration projects where code needs to be translated from Java to C++. I will open the wxMatisse project on java.net as soon as the project support all the basic widgets in null layout. If you want to collaborate, or if you know anything about NetBeans programming and want to give a hand, you’re more than welcome to join the project!

        param.setTransparentRGB(new int[]{alphaColor.getRed(),

        BufferedImage buf = new BufferedImage(width, height, BufferedImage
                                             .TYPE_INT_ARGB);

        Graphics2D g = buf.createGraphics();

        AffineTransform transform = new AffineTransform();

        // Resize to fit
        transform.setToScale(width / (double) image.getWidth(),
                             height / (double) image.getHeight());

        g.drawRenderedImage(image, transform);

        JAI.create("filestore", buf, dst, "PNG");
    }
