Update of /cvs/poppler/poppler/fofi
In directory kemper:/tmp/cvs-serv11025/fofi
Modified Files:
Tag: xpdf302merge
FoFiTrueType.cc FoFiTrueType.h FoFiType1.cc FoFiType1C.cc
FoFiType1C.h
Log Message:
The big xpdf 3.02 merge, it's mostly working except
Annot has still to be merged, i'll leave that to jrebetez
DCTStream and FlateStream classes have not been tested
ArthurOutputDev had some code commented, but as it was nto working it's not crucial
UGooString got removed as i got clear it was not needed, yay!
HtmlOutputDev won't detect links as the base outputdev changed signature
Did not test CairoOutputDev but i have 0 knowledge of Cairo so i need someone here anyway
glib frontend has some nasty warnings probably due to changed signatures, have a look
And in all i'm quite happy of the merge as it renders "something" and my kpdf port all it had was crashes :D
