Hello,
I have a japanese TrueType font for Windows NT (which is not the
standard
Microsoft japanese font as you can't install those fonts on a
german/english system) that we want to use to display japanese text.
If I use TextLayout objects with this font on a german/english NT 4.0
(SP3)
system, I only get the latin characters of that font shown, and all the
japanese
characters are just empty boxes (although "canDisplay()" returns true
for most
of the characters I want to show). If I use the same font and same
program (see below) on a japanese NT 4.0 (SP1) system, all japanese
characters
appear, even if I don't change the font.properties file to
font.properties.ja
of the runtime.Why isn't it working on a german/english NT system?
I used a Windows NT native program that displays all characters of a
font
and this worked on both system (english/japanese).
Any ideas?
Too play around with fonts, I attached a little program, that lists all
fonts found in a listbox. If you click on one,the characters 32-300 and
10000-35000 (if displayable) are shown.
It consumes a lot of memory (about 40Mb) for the BufferedImage the text
is written too, and
it is slow, so take your time. And its a hack as well.
Regards,
Knut
