I write artical with lyx and generate the pdf file. But when i see the effect use xpdf, it displays nothing and says as follow: Error: This document uses Type 3 fonts - some text may not be correctly displayed. My question is: 1, Can xpdf display pdf file with type3 fonts? If it can, please tell me how to do! 2, If xpdf can't display pdf file with type3 fonts, can i setup lyx or pdftex to generate pdf file without type3 fonts? thank very much!
