Swing & Batik: Create an ImageIcon from an SVG file?

It's really quite easy, just not very intuitive.

It's really quite easy, just not very intuitive. You need to extend ImageTranscoder. In the createImage method you allocate a BufferedImage, cache it as a member variable, and return it.

The writeImage method is empty. And you'll need to add a getter to retrieve the BufferedImage. It will look something like this: class MyTranscoder extends ImageTranscoder { private BufferedImage image = null; public BufferedImage createImage(int w, int h) { image = new BufferedImage(w, h, BufferedImage.

TYPE_INT_ARGB); return image; } public void writeImage(BufferedImage img, TranscoderOutput out) { } public BufferedImage getImage() { return image; } } Now, to create an image you create an instance of your transcoder and pass it the desired width and height by setting Transcoding Finally you transcode from a TranscoderInput to a null target. Then call the getter on your transcoder to obtain the image. The call looks something like this: MyTranscoder transcoder = new MyTransCoder(); Transcodingnts hints = new Transcodingput(ImageTranscoder.

KEY_WIDTH, width); hints. Put(ImageTranscoder. KEY_HEIGHT, height); transcoder.

SetTranscodingtranscode(new TranscoderInput(url), null); BufferedImage image = transcoder.getImage(); Simple, right? (Yeah, right. Only took me 2 weeks to figure that out.Sigh.).

Yep, what Devon said. :) Here's my SVGIcon class which pretty much does that: mcc.id. Au/2005/04/SVGIcon.

I have just followed Devon's approach with Batik-1.7 However, in order to make it work I had to make the following additions to the hints object: MyTranscoder transcoder =new MyTranscoder() DOMImplementation impl = SVGDOMImplementation. GetDOMImplementation(); Transcodingnts hints = new Transcodingput(ImageTranscoder. KEY_WIDTH, width); // e.g. Width=new Float(300) hints.

Put(ImageTranscoder. KEY_HEIGHT,height);// e.g. Height=new Float(75) hints. Put(ImageTranscoder.

KEY_DOM_IMPLEMENTATION, impl. GetDOMImplementation()); hints. Put(ImageTranscoder.

KEY_DOCUMENT_ELEMENT_NAMESPACE_URI,SVGConstants. SVG_NAMESPACE_URI); hints. Put(ImageTranscoder.

KEY_DOCUMENT_ELEMENT_NAMESPACE_URI,SVGConstants. SVG_NAMESPACE_URI); hints. Put(ImageTranscoder.

KEY_DOCUMENT_ELEMENT, SVGConstants. SVG_SVG_TAG); hints. Put(ImageTranscoder.

KEY_XML_PARSER_VALIDATING, false); transcoder. SetTranscoding TranscoderInput ti=new TranscoderInput(uri) transcoder. Transcode(ti, null); BufferedImage image = transcoder.getImage(); Seems like something has been updated in batik's XMLAbstractTranscoder( http://svn.apache.org/repos/asf/xmlgraphics/batik/tags/batik-1_7/sources/org/apache/batik/transcoder/XMLAbstractTranscoder.java) with version 1.7.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
