Hi guys, I am having a problem exporting a scene to a format like .eps and .pdf. I tried Paraview 4.4.0 to export a .pdf and the results of that is

PDF obtained in version 4.4.0 (maybe you should download the file to your computer to see it with more detail)

But when I try the same option in Paraview 5.1.1 or Paraview 5.1.2, the result is

PDF obtained in version 5.1.2

As you can see the results are different when zooming. For me the correct file is the first one (4.4.0) because it does not look blurred when zooming. For both I am unchecking the export option 'Rasterize 3D geometry'. I would like to know if this is a normal behaviour or I am missing something, maybe is related with gl2. Thanks in advance.

The reason for the diffrences in zooming is, the export from paraview 4 vectorized and the export from paraview 5 is rasterized. With the switch to the new Opengl version in paraview 5 seems to have dropped the feature of vectorized output:

If you have found any way to obatin a vectorized image in the mean time please let me know.

Hi everyone,

maybe this solution might help someone:

I'm using Paraview 5.0.1 64-Bit and vector export for me works with the following settings:

-- If your image is color coded (e.g. a color map is applied to pressure), you need to select the un-interpolated data set. In the drop-down menu, where you select the parameter to be shown - e.g. p or u - just select the one with the little cube next to it, not the one with the dot. Exporting interpolated data as vector graphic only results in an empty image for me.

-- Select Flie -> Export Scene -> choose .pdf from the drop-down menu -> click the little gear symbol on the top right of the window to show advanced options -> de-select "Rasterize 3D geometry"

-- You can now optionally change the different settings. The "GL2PS depth sort method" influences file size and appearance of your .pdf file


This works fine for me, the resulting .pdf is a vector image that you can zoom into without seeing individual pixels.

Hope I could help,
Endel
