Unfortunately Java does not support SVG by default. But there is a great Apache Project aiming just for this purpose called batik.
Although the reference and documentation is pretty well, it does not cover loading an SVG and just saving it as a BufferedImage.
Here’s an example of how I did it:
Write a simple Transcoder
class BufferedImageTranscoder extends ImageTranscoder { @Override public BufferedImage createImage(int w, int h) { BufferedImage bi = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB); return bi; } @Override public void writeImage(BufferedImage img, TranscoderOutput output) { this.img = img; } public BufferedImage getBufferedImage() { return img; } private BufferedImage img = null; }
Using the Transcoder
public static BufferedImage loadImage(File svgFile, float width, float height) { BufferedImageTranscoder imageTranscoder = new BufferedImageTranscoder(); imageTranscoder.addTranscodingHint(PNGTranscoder.KEY_WIDTH, width); imageTranscoder.addTranscodingHint(PNGTranscoder.KEY_HEIGHT, height); TranscoderInput input = new TranscoderInput(svgFile); imageTranscoder.transcode(input, null); return imageTranscoder.getBufferedImage(); }
Funny, I just got in contact with batik as well recently, for converting browser generated charts in svg. Though I avoided its use by converting the svg to a canvas with the js lib canvg, which in return can be saved as png directly.
