[edit] Description

A script to display RGB and CMY levels and a RGB parade color scope.

[edit] Requirements


[edit] Syntax and Parameters


[edit] HistogramRGBLevels / HistogramCMYLevels

These two functions are like Histogram("levels") but for RGB and CMY instead of YUV.

HistogramRGBLevels (clip input, bool "range", float "factor" )
HistogramCMYLevels (clip input, bool "range", float "factor" )


clip  input =
Input clip.


bool  range = true
Set range=false to hide the 16-235 range (a left-over from the Y histogram used to build these)


float  factor = 100.0
The "factor" option specifies how the graphs are displayed. It is specified as percentage of the total population.
Range: 0.0 to 100.0



[edit] HistogramRGBParade

Presents a fairly standard RGB parade color scope. It uses Histogram("classic") for each RGB component, but applied to columns rather than rows.

HistogramRGBParade (clip input, float "width" )


clip  input =
Input clip.


float  width = 0.25
Controls the width of the histogram display (height will always be 256 pixels).


[edit] Examples

  • HistogramRGBLevels with default settings: 
AviSource("blah.avi")
HistogramRGBLevels(range=true, factor=100.0)

  • HistogramCMYLevels with default settings: 
AviSource("blah.avi")
HistogramCMYLevels(range=true, factor=100.0)

  • HistogramRGBParade with default settings: 
AviSource("blah.avi")
HistogramRGBParade(width=0.25)
