High Resolution (DPI) Images

Creating Resolution Specific Images

We often get the question:

Q.  How do I create a X DPI image using PyMol's 'ray' command?

The answer is deceivingly simple. There are two steps in the process. First, setup your scene and use ray like this

ray 2400, 2400

From this you will get a large square image. You can now resize it to X inches where X=A*B, A and B factors of 2400 (eg: 8 inch photo @ 300DPI, 4 inch photo at 600DPI, 2 inch photo @ 1200DPI). Using PhotoShop or GIMP resize the photo to the appropriate height and width while making sure also to tell the PhotoShop or GIMP what resolution the image is.

GIMP 2.0

In Gimp, load your image (it'll most likely be very large) then

  • Select:
Image ->
Scale Image ->
'Print Size & Scale Image Section' change 'New Width' to whatever width you decided on before.
  • Save Image (File->Save)

You should be set.
