Bonjour à tous!
I was wondering if anything changed about the way OpenEXR handles empty
data window since 2005. The latest news I have are:

Is this possible now to write a file with no pixel in it? If not, to
represent an empty data window, I would need to write a single black
transparent pixel to a file and set the data window to (0,0) - (0,0) as Ken
suggested in 2005. But then, is there a way to tell apart a file with an
empty data window and a file of size 1x1 containing only one pixel?
Thank you!
