Hi everyone, I am a beginner in paraview. I am trying to use paraview to generate some images to build a training set for machine learning. This requires that the actual size of each image is the same. For example, in a 512x512 image, each pixel dot corresponds to 1mx1m square, so that the images used for training are not distorted. I have seen that there is an option setting for resolution in file→save screenshot, but this doesn’t seem to explain well the problem of its scale to the real size. I have also tried searching in this forum and did not find a similar answer.
Thanks again guys!

The size of the pixel is just the size of the pixel, there is no units in VTK or ParaView.
