Re: [Openexr-devel] DisplayWindow example images - -1, -1 display window origin?

[Florian Kainz]

Paul,

Unless the files have changed recently, the DisplayWindow test files are
all as intended; please see the README file in the directory that also
contains the t??.exr files.

OpenEXR allows negative coordinates for the display window and data window.
OpenEXR also does not prescribe any particular spatial relationship between
the data window and the display window.  The two windows will usually
overlap, but they don't have to.  Some of the t??.exr files are meant to
test application behavior for the non-overlapping case.
