Hi,
I am just not able to embed fonts into my PDF images while using
PDFTranscoder. As a result, the PDF's are quite large.
I created a config file with the font declarations and used the
Config builder to configure the transcoder. But it does not embed the fonts.
I could be doing something wrong; but I don't know what. I tried to remove
the <fonts> tag in the config file; but even that did not help.
What is interesting is that when I tried to convert my SVG (with
embedded fonts) into a PDF using the batik-rasterizer.jar utility, it
actually gave me a PDF with embedded fonts. In this case, I hadn't even
provided any font information. What is the reason for this?
Also, if this *phenomenon* can be banked on, can I try and use the
batik-rasterizer utility from within my application?
Is there any semi-stable release of FOP since 0.20.5 where the
"xml:space" attribute is respected and which is ready for use in
applications. It need not have all features that are there in the current
version - I just want that attribute to be respected. If such a release does
not exist, is there any code snippet that recognizes the "xml:space"
attribute which I can plug into the 0.20.5 code and rebuild the fop.jar file?
Wish you a Merry Christmas.
Thanks,
Saptarshi.

Now that I look at this a second time I realize that you mean that
you've solved the problem. D'Oh.

Yes, I think so. If there are any problems just recreate the font
metrics using the PFMReader and TTFReader from FOP's CVS HEAD. But there
shouldn't really be any differences.

I've seen that there are sometimes multiple names for a single font
which can lead to a certain amount of confusion.

I've seen behaviour like this before but until today haven't
investigated, yet. Simply use the same names in your font configuration
XML so the font gets detected. You can define aliases (i.e.
font-triplets) there.

Do

FOP's :-) PDFTranscoder cannot use these embedded SVG fonts. They are
handled by Batik. There's a todo item where these embedded fonts should
be converted to Type3 fonts but that's not implemented, yet. I suggest
you do the same stripping you've done for FOP.
