Actually, i must apologize By calling fonts by their real name eg: "WenQuanYi Zen Hei" (instead of wqy-microhei, their file name), i can display them. So no worries for issue 2. However, I do not manage to export the png to pdf or eps due to the following error:
"TrueType font is missing table" Is that due to my changing the font name from *.ttc to *.ttf? regards, benoit Quoting Benoit Gaillard <benoit.gaill...@univ-tlse2.fr>: > Hi, > > When looking in my fontFile.cache, i did not find any of > '/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf', > '/usr/share/fonts/truetype/wqy/wqy-microhei.ttf' or simhei. this is why > i could not display the characters. > > I deleted the cache and re-lounched my script, so that mpl had to look > for the fonts and update the cache.
