Hi Craig,

That's true of FOP trunk, but we have developed advanced font support
for Postscript in a branch named TTFinPostscript, which we've
successfully used to generate Chinese and Thai output. If you checkout
and compile the branch you can use the feature too. Although I believe
there are a few bugs which are fixed by a (as yet unapplied) patch in
Bugzilla. So if you run into a bug using the branch you will need to
apply the patch.
Ooh, that's promising. I'll check it out.
(On a side note, I wonder if fop'll move to git at any point?
Bugzilla-patch -> svn branch isn't the most fun workflow for
non-committer contributors).
I know there's a lot of folks in favour of GIT. There's been a lot of
discussion on infra@ about moving Apache projects to GIT. Personally I
don't understand why GIT helps with applying patches. It's easy to
switch your SVN sandbox to the branch or create a new checkout from the
branch. Applying the patch is just a question of right clicking on the
patch file and choosing "Apply Patch" then running through the file list
and clicking save if there are no conflicts. There shouldn't be any
conflicts, Mehdi prepared the patch against the TTFinPS branch.
To me GIT seems overly complicated for the day to day tasks of
developing against a handful of branches.
Thanks,
Chris
I'm working on implementing font subset merging in fop-pdf-image, or at
least font re-embedding, but it's quite complicated to do and will take
time, esp as I have to get this project out the door and working ASAP so
I can't put too much time into that right now. I seem to be hitting
another limitation whenever I find a workaround for one, though.
We've discussed this before. Mehdi sent Jeremias a patch offlist to
partially resolve this, but its only for fonts within the same input
PDF. If you have lots of smaller PDFs then the fonts won't be
de-duplicated. If you do get round to developing a more advanced
de-duplication then we'd love to see a patch :-) If you need Mehdi's
patch then feel free to yell and I'm sure Mehdi will happily post it
here.
I'd love a copy, yeah. I'm not sure how much it'll help, as font merging
across PDFs requires more information to be shared between image plugin
invocations than is currently possible and requires image plugins to be
notified just before the trailer and resource dict are written out, too.
The biggest problem will be the logic of actually merging subsets,
though. I'm finding it astonishingly hard to find good information on
how fonts are actually subset for PDF - the PDF ref doesn't say much at
all about how the actual embedded font file is altered for subsetting.
