Examples of org.apache.xmlgraphics.java2d.Graphics2DImagePainter

org.apache.xmlgraphics.java2d.Graphics2DImagePainter
This interface is used to paint vector graphic images. Components that can paint using a Graphics2D instance (i.e. Java2D) can implement this interface to paint themselves.

        int width = svg.getSize().getWidthMpt();
        int height = svg.getSize().getHeightMpt();
        Dimension imageSize = new Dimension(width, height);

        //Create g2d image
        ImageInfo imageInfo = src.getInfo();
