<p dir="ltr">The first image is generated on a windows machine and the second is done on a Linux machine. The same random seed is used but the random number generator is different for windows & Linux hence the different shaped hills. Both images should be 800 x800.<br>

Clearly contains:<br>
renWin->SetSize(800, 800);<br>
<br>
Why, then does the alternate valid image "Testing/Baseline/<u></u>Visualization/<u></u>TestCurvatureBandsWithGlyphs_<u></u>1.png" [1] in the VTK wiki examples git repository have dimensions 800 x 771? Why is an image of a different size considered valid?<br>
<br>
And ..... why are the images so different? Shouldn't the randomly generated images seen in this example be identical because of random seeding? Compare to the primary baseline image at [2].<br>
<br>
<br>
Thanks for any insight,<br>
