Hi:
I don't know what you mean by "pdf text" -- do you mean ODS PDF or do you mean "Print to PDF" from within Web Report Studio????
If you mean ODS PDF, then you might want to review this SAS Global Forum paper on PDF and 9.2 -- they recommend a DPI of 150 for images:

If this does not resolve your problem or, if you are talking about some other issue than DPI or you are experiencing issues in Web Report Studio, then you might want to work with Tech Support.
