I am rendering a two dimension scalar field. I add colors with "AutoGreyScale" and iso-contours with "Isosurface". The dimensions (in world coordinates) are exactly pi X 2*pi. What I wanted to do is set the width of the Camera to 2*pi and the aspect ratio to 0.5, thus that there is no area of white around the image. But apparently if you choose a with of 6.28... then several pixels scattered over the image remain white. If I choose a width of 7 exactly instead, the image is rendered correctly. Perhaps I can add an example of the good and erroneous rendered images as attachments, then it is more clear what I mean.
