[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.
- clip input =
- bool range = true
- Set range=false to hide the 16-235 range (a left-over from the Y histogram used to build these)
- bool range = true
- 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
- float factor = 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.
- clip input =
- float width = 0.25
- Controls the width of the histogram display (height will always be 256 pixels).
- float width = 0.25
[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)
