Hey,
i will create a patch today and send it in (but i dont know how long it
will take to be in a release version/branch of podofo).
Releasecycles... yeah... i dont know :D
I guess you have to apply the patch on you local podofo and build it.
greetings Dennis

Hi
Thanks for the reply.
I am not much familiar with release cycles and related info about
PoDoFo. It would be very helpful if you can provide a date(maximum
(and minimum J) no of days we may have to wait) by which the fix will
be released as our requirement is somewhat heavily dependent on the issue.
……………
I have not tested CreateFontIndirect(), but I always thought it would
always return failure when it can’t find the font matching with name.
Even if the other qualities don’t provided in LOGFONT match , it
would return some font (with other qualities)in the same family. (The
function can return NULL).<< _“ __The best method is to try one name
and, on *failure” >>*_**My understanding here was that , the failure
mentioned refers to the failure of CreateFontIndirect() function
Thanks and Regards

CreateFontIndirect() ->
1.:
"If it fails to find an exact match, it provides an alternative whose
characteristics match as many of the requested characteristics as
possible."
2.:
"The fonts for many East Asian languages have two typeface names: an
English name and a localized name.*CreateFont*
<https://msdn.microsoft.com/de-de/library/windows/desktop/dd183499%28v=vs.85%29.aspx>and*CreateFontIndirect*take
the localized typeface name only on a system locale that matches the
language, while they take the English typeface name on all other
system locales. The best method is to try one name and, on failure,
try the other. Note that*EnumFonts*
<https://msdn.microsoft.com/de-de/library/windows/desktop/dd162622%28v=vs.85%29.aspx>,*EnumFontFamilies*
<https://msdn.microsoft.com/de-de/library/windows/desktop/dd162619%28v=vs.85%29.aspx>,
and*EnumFontFamiliesEx*
<https://msdn.microsoft.com/de-de/library/windows/desktop/dd162620%28v=vs.85%29.aspx>return
the English typeface name if the system locale does not match the
language of the font."

<https://msdn.microsoft.com/de-de/library/windows/desktop/dd183500%28v=vs.85%29.aspx>
-> 1:
This means if you e.g. only provide a name and a charset in the
LOGFONT struct you can basically get any font on the PC... if the PC
doesnt have your exact font.
-> 2:
The program for which i wrote that code is using EnumFontFamilies to
show the fonts on the PC to the user. If the user has a japanese
system with an english Languangepack. Meiyro and Gothic and other
fonts will have japanese name in the UI event though i have a
languagepack installed which should switch the locale (im guessing on
this one ;D )
Therefore i first look up the locale variant of the font and see if it
matches, if it doesnt i look for the english version of the font and
use that if it matches. Works like a charm for my Software at least
^_^ (needs a refactor though, i dont like how the code looks...)
TTF:
TTFs are easier to handle because they are not Collections of fonts :D
But actually i dont know that much about how podofo handles them...
(maybe only the winApi calls will do the trick?) I only know that no
TTF font ever had any problem i know off when used in podofo :D

Hi
The fix is probably unsafe, but still I have the following questions(just
out of curiosity)
Before the call to GetFontFromCollection , two Microsoft functions ,
CreateFontIndirect() and GetFontData are called in order. Of these the first
function will give ok only if it can find font with characteristics
provided(font name, style etc), and then we have to pass GetFontData function
also. So can't we be pretty much sure we have the font we wanted?
,Currently we go only by name in GetFontFromCollection(as you mentioned).
If we also check for bold italic etc, wont this give problems in future?
Because for some fonts italic or bold version may not be available, so we
will get the regular font instead(I think this is the desired functionality).
If we tag this as failure here wont it be a problem?
Are there similar verification done for TTF fonts?
Thanks and Regards

As i said, a colleague of mine will provide a patch in (hoepfully) short
time.
Just setting if(true) is not going to solve the problem. You cant even be
sure if you have the right font if you always copy the buffer...
Second: the functionalty was build so that it could be refactored to
reconize bold, italic etc. (it doesnt care about those attributes atm it only
goes by name).
But well, if your fix fixes your problem for the moment, just remember to
update if podofo has a new version ;-)
