I am trying to create an SVG from a BufferedImage using the example at
https://xmlgraphics.apache.org/batik/using/svg-generator.html. The image is
a TIFF read from disk using Apache Commons Imaging. I can successfully
export this image to PNG. However cannot create an SVG. The code is
public static void main(String[] args) {
try {
File inFile = new File(args[0]);
BufferedImage sourceImage = ImageReadExample.imageReadExample(inFile);
// Imaging.writeImage(sourceImage, new File("sourceImage.png"),
ImageFormats.PNG, null);
// Get a DOMImplementation.
DOMImplementation domImpl =
GenericDOMImplementation.getDOMImplementation();
// Create an instance of org.w3c.dom.Document.
String svgNS = "http://www.w3.org/2000/svg";;
Document document = domImpl.createDocument(svgNS, "svg", null);
// Create an instance of the SVG Generator.
SVGGraphics2D svgGenerator = new SVGGraphics2D(document);
// Ask the test to render into the SVG Graphics2D implementation.
svgGenerator.drawImage(sourceImage, 0, 0, null);
...
When I end with `Imaging.writeImage(sourceImage, new
File("sourceImage.png"), ImageFormats.PNG, null);` a PNG is created.
However at `svgGenerator.drawImage(sourceImage, 0, 0, null);` I get this
stack trace:
java.lang.NullPointerException
