Hi,
I got the problem regarding the NoClassDefFoundErrors. The new jars
weren't mentioned in my Manifest file. I was able to generate PDF's from my
application using the PDF transcoder. However, they do not have the fonts
embedded and hence are quite large.
I had a few questions regarding font embedding.
1. Can I use the same font metrics files(xml) with Batik that I used
for FOP?
2. The SVG that I generate (using Corda PopChart) has fonts embedded
within it. Say, I was using TradeGothic CondEighteen, it appears in my SVG
as:
<!ENTITY s2 "font-family:'CF TradeGothic
CondEighteen';font-size:7;fill:#000000;pointer-events:none;"> (Note the 'CF
' prepended to the font name).
The font definition is like:
<defs>
<font horiz-adv-x="1168">
<font-face font-family="CF TradeGothic
CondEighteen" units-per-em="1024" panose-1="0 0 4 0 0 0 0 0 0 0" ascent="950"
descent="-216"/>
..........
</font>
</defs>
(Again, the font is named as 'CF TradeGothic CondEighteen').
Am I correct in saying that the 'CF ' part is supposed to be internal
to the SVG file and not to be used outside it? The font in the metrics file
is called 'TradeGothic CondEighteen' (which is what it should be).
Now, if I were to use the PDFTranscoder to convert the SVG to PDF, do
I need to replace all the 'CF TradeGothic CondEighteen' with 'TradeGothic
CondEighteen'? Also, while converting from SVG to PDF, are the font
definitions <defs><font ...>......</font></defs> taken into consideration? I
mean, does PDFTranscoder use the font definition? (When I was using FOP to do
this conversion, I used to form the FO file from the SVG file. In that, I
used to keep only the SVG part and strip the definitions. I also used to
replace the 'CF TradeGothic CondEighteen' with 'TradeGothic CondEighteen'. Do
I need to the same/similar thing here?)
I am attaching a typical SVG file that is generated by PopChart.
Regards,
Saptarshi.
