SColorGradient Class Reference

The SColorGradient class allow the user to edit a color gradient.
You cannot create a new color gradient. You can access to it by calling GetColorGradient() on a SMultiline, SPoly or SCloud. With this class you can manipulate color and cursor position of an existing color gradient. More...
