nanogui: Thread: Re: freetype font

Hi Girija,

It looks like you are mixing libraries. Are you cross compiling for 
an ARM processor? The libraries in the /usr/lical/lib directory are 
for runnning FreeType on your host machine. You will need to cross 
compile the FreeType libraries for your target platform and link 
those into your target application. I don't discuss cross compiling 
on my tutorials, they are all targeted to the X11 simulator to get 
people started with nano-X on a common platform.

Hi Gary,

I tried to cross-compile, but facing some problems.
after running 'autoconf' it gives
configure.in:171: warning: AC_TRY_RUN called without default to allow cross compiling.

I checked on web,
http://www.cs.huji.ac.il/support/docs/autobook/autobook_270.html#SEC270
It says, if one gets above mentioned warning, "This tells you that the resulting
`configure' script will not work when building with a cross compiler"
Line 171 of configure.in has  `AC_CHECK_SIZEOF' macro. The document says "which is
generally not very useful when building with a cross compiler"

So, ./configure --target=arm-linux command does not seem to work.
How do I cross-compile freetype-1.3.1 for ARM processor ?

Thanks,
Girija

hi all,
    I have installed freetype2 to support scalable chinese font.
    I have copyed simsun.ttf(chinese font under microsoft windows)to /microwin/fonts/truetype directory,and set HAVE_FREETYPE_SUPPORT to Y in config file.  but i don't know how to use simsun font in a application.what should i do? Can you tell me?

Regards and Thanks

Jason

I will comment on Freetype 1, Jon contributed
the freetype 2 code, I'm not sure if it's the
same or not...

1. HAVE_FREETYPE_SUPPORT=Y turns on support for
freetype 1, not freetype 2.

2. Set the font path prefix with
FREETYPE_FONT_DIR=/path/prefix

3. Use GrCreateFont("font.ttf", size, NULL);
to create the font.  Then selected it in
the GC using GrSetGCFont.  Then use GrText.

You can also provide the full path to the
font in GrCreateFont.  Also, the .ttf extension
is not required using Freetype1 and will be
added automatically if required.

Regards,

Greg

I'll point out the FreeType 2 (aka FT2) differences.

HAVE_FREETYPE2_SUPPORT=Y turns on support for FreeType 2.
You can't enable both FT1 and FT2.

Same for FT2.

Same for FT2.  The FT2 driver only uses Unicode
character maps, so for non-English characters I
recommend sending UC16 or UTF8 characters to GrText.
It would be possible to change the FT2 driver to use other
character maps.

Kind regards,

Jon Foster

If you take a look at my latest (April 13, 2002)
0.89pl12 CVS version, you'll see I've rewritten
the way that the older Chinese, Japanese, and Korean
fonts work.  I seperated the DBCS decoding from the
font display, so that DBCS, UTF8, UC16 and ASCII
encoded text can be displayed for FT1, FT2, PCF
and FNT based fonts.

The desired mechanism is for the font subrenderer
to support UC16, in which case all the input decoders
should work.  Shortly I plan to add support for a default
character, for unsupported glyphs.  The FNT and PCF
renderers, for speed, use an internal check for ASCII/non-ASCII
so that ASCII text doesn't always have to be converted
to UC16.

There's been a lot added, I think it's probably time for
a 0.90 release, with more regular releases.

Regards,

Greg
