Problem Using Persian Fonts

["Ali Majdzadeh" <ali majdzadeh gmail com>]

Hi Everybody

I tried to compile and run an example which I found from the list.

I installed Persian fonts and changed the source in order to show

some Farsi texts, the program compiles and runs without any errors, but

it can not load the font which I specify.

Other applications like OpenOffice and KOffice recognize my fonts.

Any ideas?


Regards

Ali
