Ok, I accept that - it was simply the appearance that the axes
indicators only altered in size with vertical scaling (but not with the
horizontal scaling) that I thought might be a bug. Hadn't actually
noticed this though until I created the examples - was not the central
tenet of the issue I was raising
And even if you set the GUI size explicitly before saving the image
you will indeed get exactly the same effect. Here's the reason: all 3D
actors in the scene as positioned using 3D world coordinates, however
all 2D entities such as scalar bar, orientation axes etc. are position
using display coordinates. So whenever you change the aspect ratio as
dramatically as you are,
They are only that dramatic because I was creating a deliberate
exaggerated example
you can expect considerable placement changes with legends and such.
For fun, setup the paraview gui and then resize the paraview windows
to mimic the aspect ratios you are using and you shall see that the
GUI behaves no differently.
This is the issue exactly "then resize the paraview windows to mimic the
aspect ratios you are using" - How do I do that for a specified
resolution ?
I think we have come back full circle to the issue I was raising. And
that is how do I set the GUI/View/Image window to a specified resolution
? At the moment the only way I can see is run a script, after altering
the size of the window with the mouse, to see what the current size is
and then repeating the process until the desired resolution is obtained
- a little bit iterative and clumsy.
Clearly from your description a scene is composed of different forms of
actors (2D & 3D) and that these behave differently when scaled in the
"save screenshot" command. Therefore in order to achieve repeatability I
need to be able to set my View/scene/image window to my desired size
each time I load paraview so that I am seeing a true representation of
what I am creating and thus avoiding any scaling at the "save
screenshot" stage.
Ideally I'd like the ability to specify the scene/image window size
directly or failing that to see its size in real time as I drag the
borders with the mouse to my desired size.
Thanks
