           Summary: Enhancements in the wmf transcoder package
           Product: Batik
           Version: 2.0
          Platform: All
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: (RFE) Request For Extension
        AssignedTo: batik-dev@xml.apache.org
        ReportedBy: herve.girod@club-internet.fr


The wmf transcoder package lacks some functionalities, so often the conversion
from standard Metafiles generated by MS PPT shows a lot of differences from the
original.

I have enhanced / hacked the actual transcoder code (as of version 1.6) and
added / corrected the following functionalities :
- manage SVG images size (currently the transcoder keeps the virtual Metafile
size, which is very large)
- manage fonts whose charset is different from the standard Latin (ex: Greek)
- manage text size and decoration (style, alignment, strikeout, underline,
escaping, clipping, background)
- manage stroke width and dash pattern
- fill with hatched and textured patterns 
- draw bitmaps enclosed in Metafiles
- correction of some errors when the size of a WMF record generated by PPT is
greater than expected
- add some of the WMF record type that are not handled by Batik 1.6

I wish to donate the associated attached code to APACHE.

attachements are :
- path file for the modifications of Batik classes
- text file for some test classes that can be useful to test the modifications
and view the structure of any WMF files
- some test cases :
  - testChart.wmf : text decorations, stroke width and dash patterns, fill with
   hatched and textured patterns
  - testGreek.wmf : charsets
  - blackShapes.wmf : PATBLT record
  - BatikWMF.wmf : images
