[HDRI] ximage and hdri

[Roberto Rodriguez]

I´m a PhD student from Argentina, member of a research team advocated to
the study of natural lighting. We are exploring the HRDI technique and we
found a limitation while using hdrgen and ximage: Only squared shapes are
avaiable to average Luminances, and we need to calculate the mean
Luminances for radial shapes (circular, toroidal) in order to get the
luminance contrast in the field of view.

How can we overcome this? Can we "borrow" the source code of ximage so we
can write a script acording to our needs?
Thank you.
