I searched but couldn't find a RGB histogram function . Is there one available for vapoursynth ?

Avisynth has a HistogramRGBLevels by -Vit-

It's actually YUV waveform, like the avisynth version of Histogram(). Which is what you would expect since:

Port of the Histogram() function from Avisynth.


Levels mode sort of works, but it looks off and the "colors" are not R,G,B

Histogram("levels") only works in avs+ for RGB, not avs classic

For vpy - I guess the shape and distribution is still "usable" if you know the order is R,G,B top to bottom

Another useful way of displaying is histogramrgbparade() in avisynth, as an RGB parade

Requesting a RGB parade and an option to only displays the histogram instead of frame + histogram. I want to implement this into vsedit2 and it doesn't need the frame.

How do I build this project? What program do I need?

I released the VSAPI4 version on my fork. Seems like jackoneill hasn't been active on github for a while to update.
I changed the "classic" mode to output a normal waveform because the original one is unreadable. I don't know if it's the right move, so correct me if you have knowledge on this.

Is it possible to update to 10bit, 12bit support ? similar to avs version ?
