Re: [libreoffice-users] Quality Assurance

Hello,

I think DiffPDF is somewhat reliable. If I also use Adobe Reader to view the potential difference, 
the comparison will be more reliable. 

If I also convert the PDF to text and compare the text files, the comparison will be very reliable.

Using three tools should make the comparison very reliable. At last, I can save some time and 
report the real bug.

Regards,
C. H. D.

Hi :)
Testing Pdf readers is an SEP (=somebody else's problem).  It would be good if we can liase with 
other office apps such as email-clients and database back-ends but our primary concern is 
LibreOffice.  I agree that if a 3rd party tool is being used then we can only use it as an 
indicator rather than having complete confidence in the result.  
Regards from
Tom :)
