Settings and Macros/GradientSlice Description

From VFXPedia

GradientSlice

Fusion 5's 2D and 3D Histogram viewers also have the ability to display gradients. The only tool that outputs a gradient is the FromImage modifier, so this macro uses that (with a Background tool to host it) to create a basic Gradient Slice tool, allowing image edge colour profiles to be easily viewed.

To use this tool, connect its source input to any image tool, and drag it into a view. Its output is actually a Gradient, not an Image, so you will not be able to connect to other tools.

• Inputs

  Start, End 

  Crosshairs that define the cross-section line on the image to examine.

  Image to scan 

  Connection to an image tool for the source image.

  Out of image color

  This sets what colour will be shown in the histogram when the cross-section line goes off the bounds of the image.

  Number of sample steps

  Increase this to get a more detailed cross-section.
