v4.1.11621 - strangeness moving from focus tool to histo

[celkins]

Hi, Robin,
strangeness after opening histogram, immediately after running multi-star focus tool - blank histo

After closing the histo window, re-opening produces what you'd expect...


Thanks,

Hi Carl,

thanks for reporting - I think the log does give part of the explanation of what happened, when you activated the histogram, it records a warning

Code: Select all

Warning	18:17:10.200185	#1 	Histogram width is only 0, not drawing histogram.	

Somehow the histogram has been told it has no space to display in, so it doesn't bother drawing (it did used to try to draw, but once you have subtracted a margin for each side you get negative pixels left and things rapidly went downhill from there).

What caused it to have zero space - not sure unfortunately. It's possible that resizing the height of the histogram area might fix the issue as that changes the size available and the histogram shoudl recieve a new size and then redraw to fill it.

I'll keep an eye out for it happening again, but I suspect it will be a tricky one to pin down unless we work out a way to make it happen repeatedly.

cheers,

Robin
