I think this works. It handles different units (in and cm). If you leave out
width or height, it gets scaled correctly. If you leave them both out, you
get whatever the current viewport size is (is there something better?).
#!/usr/bin/env pymol
from pymol import cmd
def rayy(width=-1,height=-1,dpi=300,units='in',**kwargs):
"""
Slightly better version of the ray command.
You can specify width and height in the units of your choice, e.g.
rayy 3,2,units=in,dpi=300
rayy 3in,2in
rayy 1in, 2 cm, dpi=600
Extra keyword arguments get passed on to the normal ray command.
"""
if type(dpi) in [type('')]: dpi = int(dpi)
in_per_cm = 0.393700787
def todots(x,units,dpi):
if type(x) in [type('')]:
x = x.lower()
if 'in' in x: units = 'in'
elif 'cm' in x: units = 'cm'
x = float(x.replace(units,'').strip())
if units == 'cm': x = x * in_per_cm
elif units == 'in': pass
else: raise ValueError('Unknown units (%s)'%units)
print x,units,dpi
return int(x * dpi)
# How do we get current width/height of viewport? MainSceneGetSize
perhaps
# But it doesn't matter, as PyMOL will autoscale internally for us.
try:
height,width = todots(height,units,dpi),todots(width,units,dpi)
except ValueError:
print "Unknown units"
return
print 'width',width,'height',height
cmd.ray(width=width,height=height,**kwargs)
#cmd.png(self.filename.getvalue(), dpi=int(self.dpi.getvalue()))
cmd.extend('rayy',rayy)
