Description

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
