Not sure I said that I'm on Mac OS X.
Re: palette. No reason, I prefer a white background and I was experimenting
with the colour mappings from colorbrewer

Hmm,I tried ~/ParaView-4.3.1-Linux-64bit/bin/pvpython test.py
and still created the right png - see attached.I notice you have a different
color palette. Why is that?

Thanks Dan.
Run you script through pvpython. No modifications apart from the filenames. I
still have an image with 1000x855 size (see attached).
I will try to build paraview from source to see if this changes.
Thanks

Ruggiero,Attached is the script I used on ParaView master. It saves a 1000x1000
png. I had to uncomment renderView1.ViewSize and change the magnification for
SaveScreenshot to 1.

If you send me your test.vtk I can try to generate the script on my machine.

I am using the 4.3.1 binary version downloaded from the website. I generated my
script starting from the trace as you suggest. Uncommenting the ViewSize on
your script works. The fact is that it does not work on mine and i really don't
understand why. I guess it is related to the settings of the camera.
Have you tried to run my script on your machine? I would expect to have a
square image with the data fitted perfectly into it, but as soon as I increase
the ViewSize above 855x855, only the horizontal size increases. As you can see
from the VTK the source data is 24x24.
Thanks

What version of ParaView do you use? I run the script on a ParaView source
build from git master.
You should be able to do Tools / Start Trace, open your file and then save it
to the desired resolution. The script generated should tell you what settings
you need. You might need to uncomment the setting of the ViewSize. This is what
I had to do.

The image saved is 648 x 639 (see attached). What I am not understanding is the
relation between ViewSize, camera settings and actual image size in pixels.
I would like to use paraview to render some textures that I will be using in my
code and I need the image ti fit perfectly the content.

I am trying to create a screenshot of a specific size from a [VTK file][1].This
is the code I am using

width = 24.398462354214413 width_p = int(width * dpi) heigth_p =
int(heigth * dpi) renderView1.ViewSize = [width_p, heigth_p] # reset
view to fit data #renderView1.ResetCamera() # current camera
placement for renderView1 renderView1.CameraParallelProjection = 1
renderView1.CameraPosition = [5, 5, 1000] renderView1.CameraFocalPoint = [5,
5, 0.0] renderView1.CameraViewUp = [0.0, 1.0, 0.0] scale = (heigth) / 2.0
renderView1.CameraParallelScale = scale Render()
SaveScreenshot("/Users/ruggiero/dev/test.png", magnification=1)
The problem is that the `ViewSize` seems to be ignored and I keep having images
of fixed size 1707 × 855. The height 855 seems to be a kind of limit; the only
way to get what I want is to limit the `ViewSize` to 855x855.
I have checked [this][2] question and [this][3] question, but with no success.
Any idea? I am not very confident in the settings for the camera. Could this be
the issue?
