Andrew,

It probably does work as intended in HV 7.3 -- I just can't get the same capability incorporated into CinGG because the code has morphed a lot. The goal would be to add the same option to CinGG if it might be of value. Thanks for looking at it.

Andrew,

5) Histogram plugin changes from HV 7.3 to include the option for seeing Luma only besides Color (I am struggling with this because the differences between HV and GG are becoming so diverse, that I do not think I will be able to sort it out).

Is there any way to view hv 7.3 sources online?

There is now ! https://cinelerra-gg.org/download/testing/histogram-7-3/
and https://cinelerra-gg.org/download/testing/histogram-7-2/

I put the 7-2 version out there temporarily because by comparing the 7.2 and 7.3, it is very easy to see the Luma changes. I had no problem getting the changes into the .h files (and into the window and config files), but obviously it is the histogram.C code itself that I do not comprehend.

I 'diff - u' two files and obvious commment popped out:

+// calculate histograms for the RGB channels &
+// the VALUE channel only if not automatic RGB

So May be it works as intended?
