Hi Alan, I am almost done completely rewriting the Python code under this filter. We'll make sure that this bug is addressed as part of the rewrite. I have global min/max/std deviation etc. working very nicely. I'll add support for min/max per block. I'll call them min_per_block(), max_per_block() etc.
