Summary: Massive WMFTranscoder problems
Product: Batik
Version: 2.0
Platform: All
OS/Version: other
Status: NEW
Severity: major
Priority: P2
Component: (RFE) Request For Extension
AssignedTo: batik-dev@xmlgraphics.apache.org
ReportedBy: C.Ullenboom@java-tutor.com
While transforming a wmf file -- which is exported from a MS ppt -- squiggle
and Adobe isn't able to load and render is properly. The loading can be fixed
easy, because both readers do not accept the encoding Cp1252. After deleting
encoding="Cp1252" in the svg file Adobe and squiggle will show �something� but
broken:
- The text has strange positions
- No font information is kept
- No graphics are embedded or linked
- No transparency of elements
I placed the examples here:
http://www.java-tutor.com/docs/p.ppt
http://www.java-tutor.com/docs/p.wmf
http://www.java-tutor.com/docs/p.svg
I'm using WMFTranscoder form 1.6. I tried version batik-src-06-03-08.zip too,
but got a

I guess it's the ImageWriterRegistry reporting null because it can't find any
ImageWriter implementation (just as your questions suggests). Should we throw an
exception if no ImageWriter implementation can be reported? I think that would
make sense.

I wonder if Cameron's recent fix for data url images when running
from jars will fix this problem as well. Can you retest with latest SVN?

You are right, The transcoding of the WMF goes on without any problem with an
earlier SVN version (earlier than the ImageWriter modifications, but later than
the WMF transcoder modifications). The only (known) problem was that
transparency was not handled.

It looked to me like an issue with the new ImageWriter stuff.

Interesting this worked just fine for me. I was basing my statement
on the stack trace. Does the code fail for you as well then? How are
you running the transcoder? Do you include the 'resources' directory
on the class path?

Behavior for Batik 1.6 is expected (Cp1252 stuff and problem with the resulting
image after correcting the encoding). A lot of enhancements of the WMF
transcoding process where introduced since in SVN repository.
As I submitted a huge patch for these enhancements, I consider my duty to look
at the SVN snapshot behavior...
It seems to be a problem with the texture loading from the WMF file, may be with
the cloud. I don't think that the transparency is corrected in SVN, too.
I will try to look at your examples this week-end. May be you could delete the
cloud from the image and try again, if the result is OK (apart from the
transparency), this is a "texture loading" problem in the WMF transcoding code.
