Have any of you been able to use Python to save or export an MMTK
visualisation to an image file (in any format, for example .PNG .GIF
I can use MMTK to invoke a visualisation using VRML, VRML2, VMD or VPython.
Some of these programs can export/save/render to a graphics file, and if
not then there is hallways the option of doing a screen capture. But,
this is manual, and I want this to happen automatically in code.
I suspect the easiest method may be to generate and call a VMD script
file that loads a scene and then saves it (probably using the render
Any other suggestions? For example, I would have expected VPython to be
able to save its pictures to files - but as far as I could see it doesn't.
The only other idea I could find with some Internet searching was to
make a system call to an external graphics package like ImageMagick to
take a screen capture of the entire screen. If the window was
positioned in a know place this would allow automatic cropping to get
just the desired image.
