Dear xuse2008,
Sorry for long silence.
The issue has been fixed in following specific hotfix, please download it and have a try.
http://www.e-iceblue.com/downloads/Temp ... .8.188.zipIn addition, you need to put the Spire.FontType.dll in Debug folder and reference the other two dlls into your project, and set the bool documentTextIsAsiaFont as true. Sample code:
var dx = doc.SaveAsImage(i,1500,1500,true);
If there is any question, please let me know.
Best wishes,
Betsy
