Subject Re: Configuring for Fonts included within a Spring-Boot/Camel Microservice
Date Mon, 14 Aug 2017 10:18:42 GMT

Several years ago I had the same problems with relative paths of font
files on webapps with fop jar included (it was Apache Cocoon with FOP
block and FOP jar).

I experimenting alot but no success. Digging into the logs shows me
very interesting thing, that for some reasons FOP within WAR required
some fake dir to be existent within font-base.

It is a very weird behavior, but anyway, I fixed this with the
following. Try to repeat it step by step:

1. Put fop fonts files and fop conf under resources folder as the following:
- fop.conf
- fop-fonts/fop-fonts-glyphs/<font files are here>

2. Add the following snippet in fop.conf (note about "fake" folder!):

3. Add the following snippet to fop.conf in <renderer
mime="application/pdf"> section:

<font kerning="yes" embed-url="fop-fonts-glyphs/liberation-sans-italic.ttf">
        ...any font - glyph combination here - see below sample...
          <font-triplet name="sans-serif" style="normal" weight="normal"/>
4. Try to run your app.

So the full path would be wrong from logic point of view
(fop-fonts/fake/fop-fonts-glyphs/liberation-sans-italic.ttf), but it
works for some reasons! Of course, you can remove "fop-fonts-glyphs"
dir respectively in step 1 and 3 to get
fop-fonts/fake/liberation-sans-italic.ttf , but DON'T remove the
mentioning the "fake" dir in font-base

P.S. If you use standalone FOP this tricky stuff is not needed and all
works as should be.

After trying, let me know. If this behavior will be confirmed by you,
it is the reason to file a bug in FOP BTS.
