hi everyone,
I want to display chinese in microwin application,so i modified config
file as following:
####################################################################
# Chinese Han Zi Ku loadable font support
####################################################################
HAVE_HZK_SUPPORT = Y
HZK_FONT_DIR = "fonts/chinese"

####################################################################
# Chinese GB2312 compiled in font support (gb2312font.c)
####################################################################
HAVE_GB2312_SUPPORT = Y

but i want to add another chinese font to microwin,such as simsun.ttc
truetype font in MS windows 2000.
Can i do it?and how?

regards

Jason

hi ,
to support chinese font,i set HAVE_GB2312-SUPPORT=Y and have compiled
gb2312font.c to gb2312font.o, but I don't find gb2312font in
gen_fonts[],is it not WMCOREFONT?

Here is the way that chinese font support works in the 
0.89 version.  I have just completely rewritten the
international support in the CVS version, which I will
describe following.

In version 0.89, setting HAVE_GB2312_SUPPORT=Y causes
fonts/chinese/gb2312font.c to be compiled and linked
with the server.  Howerver, the fonts are not MWCOREFONTs,
but rather use a klugy #ifdef override system 
in drivers/genfont.c and engine/devfont.c that
automatically assume that all GrText strings are
encoded in GB2312 DBCS format.  After decoding, if
the character is in the chinese font range (above 0xA1A1),
then the character bitmap is _specially_ grabbed
from the gb2312font.o file, and displayed.  Otherwise,
the current MWCOREFONT is used to display the ASCII
character.

In version 0.89pl11 CVS and later, I have rewritten
the chinese/japanese/korean font stuff entirely.  In
the new code (which works), GrText takes a flag which
specifies what format the input string is.  These
flags are MWTF_DBCS_GB, MWTF_DBCS_BIG5, etc.  Now,
the system operates differently depending on whether the
older HAVE_GB2312_SUPPORT=Y or not.  If not, then 
the system always decodes the GB2312 DBCS properly,
but you must have an MWCOREFONT or truetype font which
has characters at the A1A1 range.  If the HAVE_GB2312_SUPPORT
is set, then the system operates as before, but I have
cleaned up all the DBCS-specific code and placed it in
engine/font_dbcs.c.

With the new system you can use a converted BDF ->PCF
file for your chinese font, and just indicate the 
proper DBCS byte encoding for your GrText calls.  This
is likely the way to go, since the original GB2312 and
BIG5 fonts were converted from BDF's in the first place,
and thus don't require special handling, and are loadable.

Finally, I am just putting the finishing touches on a 
new Microwindows native font format (.fnt) - which also
includes a bdf->.fnt and bdf->.c converter so that the
same font can be compiled in, or loaded from disk/flash.
This system works now, except that it currently only
allows a 256-char ASCII index into the font.  Very soon,
I should have the 16-bit UC16 font index working, in which
case you could convert your chinese bdf font into .fnt,
and load it for display at will.

Hope this clarifies things,

Greg

hi all,
I convert chinese font simsun.ttf to simsun24.bdf by ttf2bdf and copy it
to microwin/src/fonts/truetype directory ,which is used to freetype
font. and i modified microwin/src/demos/nanox/fontdemo.c as following :

.......
#define FONTNAME "simsun24.bdf"
..............
void
do_paint(GR_EVENT_EXPOSURE *ep)
{
int i, y = 0;

for (i=3; i<=5; ++i) {
GR_FONT_INFO info;
char buf[64];

font = GrCreateFont(FONTNAME, i, NULL);
if (aa)
GrSetFontAttr(font, GR_TFANTIALIAS|GR_TFKERNING, 0);
//GrSetFontRotation(font, 150);
GrSetGCFont(gc, font);
GrGetFontInfo(font, &info);
y += info.height;

//sprintf(buf, "%d The Quick Brown Fox Jumped Over The Lazy Dog", i);
sprintf(buf, "%d 字体测试 ", i);
GrText(w, gc, 0, 24, buf, -1, GR_TFASCII);


GrDestroyFont(font);
}
but when i execute microwin/src/fontdemo.sh , it says "create font using
builtin font helvitica(1) ,hzk-createfont() simsun24.bdf not found".why?

another, what is microwin/src/fonts/truetype/fonts.dir file ,and how to
work with this file?

Jason

You must convert the .bdf to either .pcf or
.fnt in order to load the font.  These formats
are properly supported only in the CVS
microwindows version.  Use compile fonts/convbdf.c
to convert the bdf to .fnt format:

./convbdf -f simsun24.bdf

Then give the full path to simsun24.fnt
in the GrCreateFont.

Greg

Hi,
Iwant to display big-5 chinese characters. From previous discussion , I 
set in config as below:

####################################################################
# Chinese Han Zi Ku loadable font support
####################################################################
HAVE_HZK_SUPPORT = Y
HZK_FONT_DIR = "fonts/chinese"

####################################################################
# Chinese BIG5 compiled in font support (big5font.c)
####################################################################
HAVE_BIG5_SUPPORT = Y

I got error msg as below.

Pull down the microwindows-fonts-0.90.tar.gz and
extract it into the src/fonts directory.
