How to save high resolution image?
Dear Sir, I am a new user of Chimera software. I am using this software for academic purposes (i.e. research publications). I am trying to save the image with more then 600 dpi but every time i am ending up with an image of 96 dpi. I am using the POV-Ray method for image improvement but everything is going to the drain when taking the final print of the document. Can you please help me ho can i save a high resolution image? I am briefly describing my protocol of image generation: 1) I am making a density map of particular PDB file. 2) loading in the Chimera and adjusting the volume by volume viewer option 3) Coloring it using described colors 4) Using Pov-Ray for increasing effects on plane 5) Increasing the pixels to about 5000 in the pixel option 6) finally trying to save an image with 600 or 1200 dpi. But at the end of this, i am just getting an image of 96 dpi every time. Can you please help me out to make an image of higher dpi (600, 1200 or more if possible). It will be very much helpful for me if can do it. I am stuck at this point.I am badly waiting for your reply whether i can do it or should i look for some another software.

Hi Yogendra, 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. Please send questions to the chimera-users address only (not the chimera-bugs address). Thanks, Elaine ---------- Elaine C.

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. Regards - Yogendra

As far as I can tell, POV-ray images don't have the DPI setting specified in the Chimera interface. Always seems to be the screen DPI. There is a ticket for this problem now: #10683 (POV-ray not honoring DPI setting) – Chimera However, non-POV-ray images have the right DPI. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Apr 19, 2012, at 9:12 AM, Elaine Meng wrote:

I think it will be better to add this option (DPI setting) in newer versions of chimera because the images (using POV-Ray) are of very good quality on screen but not good while taking print. Its limiting the chimera to make a good publication quality figure. ----Yogendra

Hi Yogendra, I agree the problem should be fixed. In the meanwhile, however, I would also like to emphasize that Chimera can save high-quality images for publication without raytracing. Most of the images in our Image Gallery <http://www.cgl.ucsf.edu/chimera/ImageGallery/> are made by rendering directly in Chimera, not raytracing. See also the Image Tutorials <http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/frametut.html> and the "Tips on Preparing Images" <http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/print.html#tips> Regards, Elaine
Hi Yogendra, 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. -- Greg On 04/19/2012 10:35 AM, Eric Pettersen wrote:
