How
to run Typo
?
Typo servlet implements the doGet(...)
method so you can run it from an URL like :
http://mydomain/servlets/typo?font=myfont&text=mytext
You can choose the bitmap font through
the font parameter. Font file format is ffi. To
create your own ffi you need :
- a bitmap file (GIF/JPEG) with the
graphical fonts (letters should be placed in a regular
grid). You can get free fonts from D.
Guldkrans web site.
- a font descriptor : grid dimensions,
yspacing, index. Look at the example included in package
: fontser.java
- compile and run fontser.java to
create your ffi file.
You can choose the text to display
with the text parameter. As we use an URL, remember
that caracter like space have to be encoded (e.g text=hello
world ! becomes text=hello%20world%21). |
