Subject Re: Image Print size and quality
Date Tue, 17 Jan 2012 13:48:29 GMT
Hi Pascal,

yes indeed this was one of my problems.
I will test it to see the results.

In case I will still have to manipulate the image outside of the FOP do 
you have any solution to propose regarding:
How to change the print size of the image (like gimp) in order not to 
loose image quality and at the same time to show it smaller inside the PDF.

Thank you.
