The fileStats utility takes a list of image files and outputs resolution information in terms of:

• header resolution: this is the resolution as specified in the header of the image file.
• actual resolution: this is the actual resolution of the image file. This is only different from the header resolution if the image is incomplete.

The actual resolution is a good mechanism for render farms to detect if the rendering actually completed this frame (sometimes the uncompleted file is due to disk space shortage situations, or NFS problems, and the renderer may not be able to know about the problems to tell the render farm).

To use fileStats

1. From a Linux shell, type:

   fileStats <image1> <image2> <image...>
