----------------------------------
Summary: PDFTranscoder fails to auto-detect system fonts by default
Key: FOP-3087
URL: https://issues.apache.org/jira/browse/FOP-3087
Project: FOP
Issue Type: Bug
Affects Versions: 2.7, 2.6, 2.4, 2.5
Reporter: Julian Müller
Contrary to the documentation, the PDFTranscoder fails to auto-detect system
fonts by default, and also does not honor transcoding hint KEY_AUTO_FONTS =
true.
This is because the implicitly built configuration is not set up correctly.
Line 163
{code:java}
c.addChild(fonts); {code}
in AbstractFOPTranscoder needs to be moved after line 165, which is
{code:java}
fonts.addChild(autodetect); {code}
A simple workaround to this problem is to explicitly pass a correctly set up
configuration to PDFTranscoder, however, it would be preferable if
PDFTranscoder would just honor its contract.
I think this bug was introduced by FOP-2733, due to a subtle difference in
Avalon's configuration package and its replacement. Avalon's configuration
package allowed the addition of children in any order, but the new FOP
configuration package adds copies instead of the original children, so the
configuration tree needs to be built from the leaves to the root node. As of
now, the code in AbstractFOPTranscoder does not follow this new requirement and
instead builds the configuration tree from the root to the leaf.
