Dear Sir/Madam,
Thanks for your kind reply. i have already tried as you suggested but facing the
same problem. I am using the "Use Print units" in save Image dialog and also
defining the print resolution (dpi) as 600 or 1200. When i am trying to save
this without POV-Ray option, its getting saved with the defined dpi values. But
my question was How can i save a 600 dpi image using POV-Ray option. When i am
using Raytrace, the image which is finally being saved is of 96 dpi always. In
print, it does not sow the clarity and fine information.Is it a possible reason
that POV-ray option does not support more than 96 dpi image.
Please suggest how can i get the desired image quality.
