The problem is here in the geometry, which defines a _bounding_ rectangle. You also need to take into consideration that composite retains the aspect ratio of the second input (the text image that pango generated). Look at how wide that text is, but you only gave it 100% of the profile's width (640 pixels?). The composite scales down inputs to fit inside the bounding rectangle. When you go higher in text size, then it is downscaled! Try changing the first 100% to 1000% and see the difference. > </filter> > </producer> > I have attached the output as slide-25.png > > If text size is 55, for the above script, I have changed 25 as 55 > <property name="size">55</property> > For this output looks like slide-55.png > > Is there any way to get text at specified size? Use an extremely large size in your geometry to prevent down-scaling. > here some characters in the > text can be overflowed if text has more characters. You can put a line break in your CDATA section to create multiple lines of text, but the pango producer is simple and does not do word-wrapping. -- +-DRD-+ ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
