Re: [PyMOL] stereo image for publication

[Tsjerk W. <ts...@gm...>]

Hey :)

Why revert to powerpoint and or photoshop? First of all, it's not the
image resolution (dpi) that counts, it's the number of pixels, the
geometry. That you can give as argument to ray. Second, if you want a
distance between images of 63 mm, you seem to want a total image
length of 126 mm, which, when taking a 300 dpi printing resolution,
comes down to a total of 300 dpi * 126 mm / 25.4 mm/inch = 1500
pixels. Then you have to think of the height of your image, but that's
about it. If you want to change the feel of the depth, you can change
the settings for stereo_angle and stereo_shift.

stereo
fetch 1lw9
hide
show cartoon
spectrum
ray 1500,1000
png image.png

The image does have a printing resolution stored inside, which is
usually set to 72 dpi. You may want to change this, for which you can
use photosphop. But you can also do it using 'convert' from
ImageMagick (which also works on the DOS command line ;)). And you can
change the format to TIFF right away:

convert -density 300x300 image.png 300dpi.tif

Hope it helps,

Tsjerk
