This Nuke plugin mimics good old Shake’s plotScanline.
It basically scans one line and creates a graph representing the RGB values.
The values are mapped to fit within the height of the image.
Slice: decides which image row to scan
Gain: allows you to change the height of the graph curves
Mix: lowering this value will reveal the processed image
The plugin also displays the slice it’s graphing by two openGL arrows
that sit on the left and the right image edge at the height of the slice.
As opposed to the graph curves, these will not get rendered if you were
to write the result to a file.
Source code included.
Compiled for Nuke7.0.5->linux64
