Hi Yogendra,<br>
<br>
The images that Chimera generates with POV-Ray have the right number
of pixels for the DPI and image size you selected, but POV-Ray
doesn't save the DPI setting in the file. Since the DPI value is
missing from the file, your computer displays it with your screen's
resolution. So in your case, not only is the DPI different from
what you expected, but the image size is different as well. To
store the DPI in the file, you would need to use another program to
fix the file, like Adobe PhotoShop or GNU gimp. I will keep the bug
open with a request to fix up the POV-Ray output, but you already
have the right number of pixels in your image.<br>

<div>Hi Yogendra,<br>
In the "File... Save Image" dialog, if you want to enter
"dpi" you need to turn on "Use print units". Then you can
specify a "Print resolution(dpi)" value, and image width
and height in units of length (for example, inches)
instead of pixels.<br>
<br>
Please send questions to the chimera-users address only
(not the chimera-bugs address).<br>
Thanks,<br>
Elaine<br>
