Fop 1.0: resolving relative Font URLs
Hi all,
this is a new problem with fop 1.0, it does not occur in fop 0.95.
In my application I am setting the base font directory programmatically like
so:
fopFactory.setFontBaseURL("/my/font/dir");
And then I have entries like this in my fop.xconf:
<font kerning="yes" embed-url="myfont.ttf"> ... </font>
This works perfectly in Fop 0.95 and earlier versions, but in Fop 1.0 it
throws an exception:
org.apache.fop.apps.FOPException: Failed to resolve font with embed-url
'myfont.ttf'
at org.apache.fop.util.LogUtil.handleError(LogUtil.java:38)
at
org.apache.fop.fonts.FontInfoConfigurator.getFontInfo(FontInfoConfigurator.java:212)
at
org.apache.fop.fonts.FontInfoConfigurator.addFonts(FontInfoConfigurator.java:168)
at
org.apache.fop.fonts.FontInfoConfigurator.configure(FontInfoConfigurator.java:100)
at
org.apache.fop.render.PrintRendererConfigurator.buildFontList(PrintRendererConfigurator.java:106)
The release notes do say that changes with respect to font substitution have
taken place, but I believe an incompatibility like this should explicitly be
mentioned. Any ideas for a workaround?

You need to set font-base property or programmatically:
fopFactory.getFontManager().setFontBaseURL("file:///C:/Temp/fonts");

I already tried the trailing slash yesterday, when you first suggested it.
However, I had to change the code of our application for that, as it doesn't
honor the setting in fop.xconf normally. The result was the same, though.
Normally our application sets the font path programmatically and it does a
number of checks, such as whether the directory exists etc. and then calls
fopFactory.setFontBaseURL with an absolute path to the font directory.

Errmm... Sorry, too quick. I obviously meant 'the font-base'.

In that case, can you check what happens if you use a trailing slash in the embed-url?
Strictly speaking, according to the RFC, if there is no trailing slash, the base URI (if you would use java.net.URI.resolve(), which CommonURIResolver does) would be the part up to and including the last slash. If one specifies '/my/absolute/path', then the base would be '/my/absolute/', so the 'path' subdirectory would not be included...
I know FOP used to work around this as a convenience, since a lot of people appear to be unaware of that fact.

Hm, maybe it's not a problem with the FOP code itself, but with the new
version of xmlgraphics-commons included in FOP 1.0. At least there seems to
be a new class called CommonURIResolve involved, which wasn't used in FOP
0.95.

Hi,
Relative font path works for me on embed-url attribute (Windows + JDK
6.0.20), whatever FOP version (0.95, 1.0, or TRUNK):
Either on my dev machine (invoking FOP via CLI):
<snip>
<font-base>file:///D:/fonts</font-base>
<font kerning="yes" embed-url="dejavu/DejaVuSans.ttf">...</font>
</snip>
Or in production env (WinServer + JRE5 + Jboss):
- same font element in fop.xconf,
- but font-base set via
fopFactory.setFontBaseURL("file:///my/absolute/path")
no

Hi, Ulrich-
I took another look at my configuration and wanted to clarify. I ended
up using absolute paths for the embed-urls because the font files were
in a different directory than the metrics files.
However, I did have to place the <font-base> tag at the top level in the
configuration file for it to work at all. I initially located it within
the <fonts> section without any success but it worked fine when I moved
it to the top, directly following the <base> tag.
As a test, I copied the font files to the same directory as the metrics
files and used relative paths for both the metrics files and the font
files. No problems.
Sorry for the confusion.

Mehdi,
I think I know the difference between an absolute and a relative path :)
Again, I believe you're looking down the wrong path if you're looking for an
error in my configuration, because it works with FOP 0.95 and has been
working for years and years all the way back to FOP 0.20.5. It simply
stopped working with FOP 1.0.
That being said, yes, my fonts are located in /my/font/path/myfont.ttf.

Hi Ulrich,
Sorry for the late reply, but "/my/font/path" isn't a reference to a
relative path. That's an absolute path. If the absolute path of your
font were /my/font/path/myfont.ttf, then your config is correct, and
you are right in issuing a bug. But if your font is located at
<directory of fop.xconf>/my/font/path/myfont.ttf, then you need to
remove the prefixed "/". I think this may be the issue here, I
remember a commit about changing the relative directory to be relative
to the fop.xconf rather than the fop.jar.
Also, strictly speaking the proper format of a file URI in Unix based
systems is "file:///" not "file:/", though IIRC FOP treats them both
the same anyway.
I may have completely got the wrong end of the stick here, if so, my apologies.

Just a thought: it might be that the font-cache has also changed slightly between the two versions.
Try adding a line to your code like
fopFactory.getFontManager().setUseCache(false);
If that works, the more permanent solution would be to delete and regenerate the font-cache to get everything to work as expected with 1.0.

Hi Pascal,
we are running Fop embedded in a custom Java application that generates
PDFs. All I'm doing is replace fop-0.95.jar with fop-1.0.jar and our
application ceases to work. It runs on Linux. I am not changing fop.xconf at
all, neither do I change its location or anything in the directory structure
- I simply copy fop.jar and xmlgraphics-commons.jar over the old files and
restart the application.
In my mind Fop loads the correct fop.xconf file, because it contains the
very font definitions that Fop complains about not being able to resolve
(Dingbats.ttf).

Hi Ulrich,
I have no solution, only questions:
- Are the 2 FOP versions run on the same host?
- What OS do you experiment?
- Have you tried direct access to "/path/to/fonts" + "/" + "myfont.ttf"
(either with ls or dir) ?
- Does FOP 1.0 load the right fop.xconf file, if any?

I have tried both suggestions, using a file-url and appending a slash, but to
no avail.
Please keep in mind that this is a regression, i. e. not I am doing
something wrong, but something changed from fop 0.95 to fop 1.0. Take
another look at the error message:
Failed to resolve font with embed-url 'Dingbats.ttf'
The problem is not the font-base directory, but the embed-url itself, which
apparently does not work in a relative fashion anymore. Indeed, if I specify
an absolute path in the embed-url, then the font is found.

Hi Ulrich,
Have you tried using file URIs for the font-base? This would be in the
format file:///path/to/font (for unix), for windows based ones, google
will help you, I don't use Windows regularly so I wouldn't want to
speculate

Works for me with 1.0, also setting it dynamically. Try appending a
trailing slash to the font-base directory.

Hi Mehdi,
we have set the font-base to a non-existing directory and overwrite that
programmatically when the application starts. That being said, I just tried

Hi Ulrich,
Have you tried setting the font-base in your fop.xconf? I must admit I
haven't used the API much but you can set the font-base by inserting
following in the fop.xconf:
<font-base> ** the base directory ** </font-base>
The configuration page on the fop website may help you,
http://xmlgraphics.apache.org/fop/0.95/configuration.html, if you have
more questions, if that doesn't help, don't hesitate to ask.
