Summary: TranscoderException and EnclosedException when transform
a svg- to jpeg-file
Product: Batik
Version: 2.0
Platform: PC
OS/Version: Linux
Status: NEW
Severity: critical
Priority: P2
Component: SVG Rasterizer
AssignedTo: batik-dev@xmlgraphics.apache.org
ReportedBy: ks@vitronic.de
Hi,
when I try to follow the description on
http://xmlgraphics.apache.org/batik/using/transcoder.html#createImage
to create a jpg-image file from a svg-file in a JUnitTest, I get the following
error message:
org.apache.batik.transcoder.TranscoderException: null
Enclosed Exception:

The batik version I use is 1.7.
First I tried to transform a created svg-file into jpeg-file in my own
application, but I get the same exception, so I copied the example code from
the previous mentioned website in a JUnit-Testcase to figure out if I have done
anything wrong in my application. But I got the same problem again, with the
copied and pasted code (see above).
When I ran the rasterizer.jar file to convert the image, there is no such an
exception thrown. I looked at the code from SVGGenerator from the Rasterizer
application, but I doesn´t found a solution, so far to solve the problem.
So here is the code from my JUnitTest method:
public void testJPEGTranscoder() {
// Create a JPEG transcoder
JPEGTranscoder t = new JPEGTranscoder();
// Set the transcoding hints.
t.addTranscodingHint(JPEGTranscoder.KEY_QUALITY, new Float(.8));
// Create the transcoder input.
String svgURI;
try {
svgURI = new File("test/TestInput.svg").toURL().toString();
TranscoderInput input = new TranscoderInput(svgURI);
// Create the transcoder output.
OutputStream ostream = new FileOutputStream(
"test/TestOutput.jpg");
TranscoderOutput output = new TranscoderOutput(ostream);
// Save the image.
t.transcode(input, output);
// Flush and close the stream.
ostream.flush();
ostream.close();
// System.exit(0);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TranscoderException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Thanks in advance for your help,
ks

So a good fix for this "issue" would be a better error message (basically,
mimic the PNG behavior) for the JPEG and possible other raster formats.
Patches are welcome! ;-)
(I've stated "issue" because, formally, this issue should be considered invalid
due to the nature of the cause itself: a missing dependency. But, as we can do
better - the PNG output is the example here - we then _should_ do it! :-) )

Hi,
I found the cause for the resulting exception. It was a missed dependency for
the transcoder.
The following dependency must be included in the "batik-transcoder-1.7.pom", to
get the example work as expected (see
http://xmlgraphics.apache.org/batik/using/transcoder.html#createImage).
<dependency>
<groupId>org.apache.xmlgraphics</groupId>
<artifactId>batik-codec</artifactId>
<version>1.7</version>
</dependency>
I´ve tried the transcoding of an png-image, insted of a jpeg-image, to see if
I would run in the same problem. The problem showed up again, but the
error-message, which was this time from the PNGTranscoder, gave me the hint I
needed.
"Could not write PNG file because no WriteAdapter is availble".
Aha. A short search in the PNGTranscoder source led me to line 110.
WriteAdapter adapter =
getWriteAdapter("org.apache.batik.ext.awt.image.codec.png.PNGTranscoderInternalCodecWriteAdapter");
And another short search in the libraries of my project, showed me that there
was the batik-codec-1.7.jar library missing.
I added that one to my projects pom.xml, ran maven and the JUnitTest again, and
the image was created. :-)
I currently use the repository
http://repo1.maven.org/maven2/org/apache/xmlgraphics/.
I don´t know where the base-repo is. So could someone with write access to the
base-repo add the dependency to the "batik-transcoder-1.7.pom"
and close this bug afterwards?
Thanks
Best regards
ks
