beginner here... ;)
I'm writing a little GUI in PYQT5 to display images and I'd like to add
this histogram function.
The problem arises when my images are almost or completely black.
In case of an image with all 0 pixels the histogram breaks my application
raising the following error:
> line 464, in getHistogram
> bins = np.arange(mn, mx+1.01*step, step, dtype=np.int)
> ValueError: arange: cannot compute length
In case of an image with very few counts the histogram breaks my
application raising the following error:
> Files\Python36\lib\site-packages\numpy\lib\function_base.py", line 727, in
> '`bins` must increase monotonically, when an array')
> ValueError: `bins` must increase monotonically, when an array
Any idea for any solutions?
I don't have the knowledge, unfortunately, to modify the widget myself.
ps... I will prepare a minimal example in few hours, but I preferred to
post this first
