I should have added that I have now just learnt that the export option
and specifying the size will produce similar images - but that they
aren't what i actually see on the screen. Very frustrating as I set
the visual composition based on what I see on the screen.
It would help if you sent the screen shot.

When you write an image, you can specify a resolution to use
independent of the size of the GUI. If you type in the same
resolution every time, you should get the same projection.

Hi,
I'm using to paraview to create screenshots of multiple sets of data
(12+). Each dataset is located in a separate file and may have
different
boundary conditions or different surfaces. (i.e. they are not
identical
- although they *might* have elements in common and their domain
size is
the same). I've written a simple script (below) using python to
set my
camera angle the same between loading the state for each scenario
However, I have one difficulty, if I have exited paraview or
resized the
windows (or ....@.. it crashed ) the size & aspect ratio of the
window
displaying my 3D view may change. This results in my screenshots have
differing resolutions i.e. my first series had 1198x712 but my
next was
1106x780. I know you can specify this resolution in the save
screenshot
dialog - however this is after the fact and some elements seem to
differ
based on the real size (i.e. legends)
I can't seem to find an option to specify the size of this
window, but I
assume I may be able to via python ? can anyone help with this ?
Also would love to know how to move the location of the
orientation axes ?
For reference, I am not a python programmer ( but can program C, C++,
Fortran ... ) so forgive any style mistakes.
Thanks, John
My quick script to set camera state is: (iso_L.py)
#!/usr/bin/env python
from paraview.servermanager import *
if not servermanager.ActiveConnection:
connection = servermanager.Connect()
view = servermanager.GetRenderView()
camera = view.GetActiveCamera()
view.CameraPosition=[0.5,-4,4]
view.CameraFocalPoint=[2.915, 0, 0.821]
view.CameraViewUp=[0, 0, 1]
view.CameraViewAngle=30
#view.ResetCamera()
view.StillRender()
