nanogui: Thread: Using own true type font with Nano-X

Hi All,
I have putted mail on the list previously regarding this.
I want to use my own True Type Font with Nano-X, I have putted that font
in fonts/truetype directory.
I tried to recompile fontdemo sample program where i am using my font,
but while running it i am getting error that "font not found" and it
uses the first default font.
what i need to do to use my font with Nano-X.
I have made freetype support ON and font directory path is also correct.
Please give me some pointers to resolve this problem.
Is there any thing i am missing?

Thanks and regards,
Kiran

You also need to update the 'fonts.dir' file.
There was a problem with loadfont.c file that I provided a patch for.
You may want to search for that too.
The TTF fonts work for me.

Thanks Martin for reply.
I have already updated font.dir, but still i am getting same error.
I am not using nxlib. I just trying to run fontdemo program with my
truetype font. But its not able to find that font.
I am not able to understand why it is not able to find that font?
I tried by disabling other font supports for sake of trial, but ended up
in the same result!

Kiran

When I was debugging my problem with 'TTF fonts not found', I put a
printf() in a search (loadfont) routine to show me what fonts were
searched and what font I was looking for.
This showed me exactly what the problem was.
I cannot tell you what your problem is without knowing what is going on.
Do the printf's and then we will see.
It is either looking for a wrong front (no match) or at the wrong
directory.

hi Martine,
Sorry but i couldn't find loadfont routine you said me!
but i am sending the changes i have made in "fontdemo.c" file for
debugging purpose along with the output i am getting. 
The GrGetFontList() is showing my fonts (dvsr0ntt.ttf and DVWSR0NT.TTF).
Please have a look and tell me what would be the problem?

Is your font actually named within the filesystem in
upper case?  This looks like an MSDOS compatibility
issue, and the Linux filesystem differentiates between
upper and lower case.  

Regards,

Greg

The problem with TTF fonts is that inside the 'loadfont' routine it
generates a file name differently than the ones you printed.
It uses the size/bold/italic of the font also.
You need the print the files names it searches for in loadfont.c to
really find out why it is failing.

thanks for reply.
yes it is in upper case on my file system also. you could know it by
having a look at the output i have sent. 
it is showing MW name in upper case.
I had this doubt so i tried by renaming my other true type file
(dvsr0ntt.ttf) to lower case but can't succeed!

thanks and regards,
Kiran

The above fonts are different names.

My suggestion is to work only with ONE font, and
debug the problem one font at a time.  The
TTF system works, so its likely a font naming or
upper/lower case problem.  Change your system
to use only a single font.  Perhaps the font conversion
utility is putting the font name inside the font file with
the wrong case?

Regards,

Greg 

thanks!
I tried with the one font first. I tried with the font dvsr0ntt.ttf.
name of this font was in upper case. I checked with it by keeping it in
upper case, then after getting error I renamed it to lower case.
after doing with this font i tried with other font (DVWSR0NT.TTF) also
for sake doubt! but end up with same result. I have made entry for both
the fonts in the font.dir. 
Is there any other file where I need to make entry for those fonts?

thanks and regards,
Kiran
