Subject RE: Chinese PDFs and non embedded fonts
Date Fri, 20 Apr 2012 14:15:52 GMT

Hello,

Can you just confirm that when using the referenced-fonts method, the <auto-detect />
line is within a <fonts> tag pair in the renderer?

If it is not, then that may be why it is refusing the find the font you are referencing.

Best Regards,

Robert Meyer

font metrics file is created. The table below summarises the differences between these two
encoding options as currently used within FOP. Please note that this information only applies
