I'm using Batik and Itext to convert svg files to pdf. It works great with
one problem: the resulting files are large. I think it is due to the font
being drawn as shapes.
Is there a way to keep the svg text as text through the conversion?
I didn't use FOP since the readme states it doesn't handle transparency
which I require.
Are there any Transcoding hints?

Here is the test code - used batik-cvs-05-04-03 and iText (itext-paulo-153)
jars.
When the text is "Hello" the filesize is 1661.
When the text is "HelloAbcde" the filesize is 2569 which works out to about
200 bytes per character.
