tntim96 commented on FOP-3054:
------------------------------
That works. So in summary, we have to now set the custom resource resolver for
the font manager with:
{code:java}
ResourceResolver rr = ResourceResolverFactory
.createTempAwareResourceResolver(new InMemoryTempResourceResolver(), new
CustomResolver());
//Adding rr resource reolver in here doesn't affect the font manager
FopFactoryBuilder fopFactoryBuilder = new
FopFactoryBuilder(URI.create("https://www.fop.com.au/";), rr);
//...code skipped. Lines below are new
InternalResourceResolver internalResourceResolver =
ResourceResolverFactory.createInternalResourceResolver(URI.create("https://www.fop.com.au/";),
rr);
fopFactory.getFontManager().setResourceResolver(internalResourceResolver);
{code}
...and can be seen in [this
commit|https://github.com/tntim96/FOP-3054/commit/a60bf7774786c7eaf7d35a27c32338d626c29eb2].
Is this a bug though? Users might expect the higher level resource resolver (in
FopFactoryBuilder) to be passed through to the font manager?
