Re: SVG which renders in 1.7 fails in 1.8pre

[DeWeese Thomas <th...@gmail.com>]

Hi Joel,
	I suspect that you are missing some of the SPI files in the jar file you are building from 1.8pre.
Do you have the files from resources/META-INF/services/* in your jar files?
These may not have been needed in 1.7 (since defaults were included).

	Thomas

Re: SVG which renders in 1.7 fails in 1.8pre

Thus spake DeWeese Thomas:

In batik-codec.jar:

  META-INF/services/org.apache.batik.ext.awt.image.spi.ImageWriter
  META-INF/services/org.apache.batik.ext.awt.image.spi.RegistryEntry

In batik-extension.jar:

  META-INF/services/org.apache.batik.bridge.BridgeExtension
  META-INF/services/org.apache.batik.dom.DomExtension

In batik-script.jar:

  META-INF/services/org.apache.batik.script.InterpreterFactory

So it looks like I have the resources files in JARs on my classpath
(except the resource file for Squiggle, which I assume is not necessary
for anything but Squiggle.)

I also have a short test case now which exhibits the problem for me:


import java.awt.image.BufferedImage;
import java.io.File;

import org.apache.batik.transcoder.TranscoderInput;
import org.apache.batik.transcoder.TranscoderOutput;
import org.apache.batik.transcoder.image.ImageTranscoder;

public class Test {
  private static class Rasterizer extends ImageTranscoder {
    public BufferedImage createImage(int w, int h) {
      return new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
    }

    public void writeImage(BufferedImage img, TranscoderOutput output) {
    }
  }

  public static void main(String[] args) throws Exception {
    final String uri = new File(args[0]).toURI().toString();
    final Rasterizer r = new Rasterizer();
    r.transcode(new TranscoderInput(uri), new TranscoderOutput());
  }
}

Here's the command line:

java -cp lib/batik-anim.jar:lib/batik-awt-util.jar:lib/batik-bridge.jar:lib/batik-codec.jar:lib/batik-css.jar:lib/batik-dom.jar:lib/batik-ext.jar:lib/batik-extension.jar:lib/batik-gui-util.jar:lib/batik-gvt.jar:lib/batik-parser.jar:lib/batik-rasterizer-ext.jar:lib/batik-script.jar:lib/batik-svg-dom.jar:lib/batik-svggen.jar:lib/batik-swing.jar:lib/batik-transcoder.jar:lib/batik-util.jar:lib/batik-xml.jar:lib/xerces_2_5_0.jar:lib/xml-apis.jar:lib/xml-apis-ext.jar:. Test tmp/images/Ottoman_hand.svg

Here's the exception:
