ChangeGradientColor(TSVGCustomGradient,TSVGColor,Boolean)

Overloaded.  Attempts to modify a gradient color scheme to a similar color scheme using NewColor, i.e., if a gradient has 3 gradient stops of dark gray, gray, white and the NewColor is Red, the method will try to change the gradient to red, lighter red, and white.

The FromFirst parameter specifies if the first or the last gradient stop is the base color to replace. The base color is replaced with the NewColor unchanged. All other gradient stops are modified from the base color.

ChangeGradientColor(TSVGCustomGradient,TSVGColor,Integer)

Overloaded.  Attempts to modify a gradient color scheme to a similar color scheme using NewColor, i.e., if a gradient has 3 gradient stops of dark gray, gray, white and the NewColor is Red, the method will try to change the gradient to red, lighter red, and white.

The BaseColorIndex parameter specifies if which gradient stop is the base color to replace. The base color is replaced with the NewColor unchanged. All other gradient stops are modified from the base color.

DoEnableGradient(String,String,Boolean,TSVGColor,Boolean)

Helper method for changing a SVG element's color between a gradient or a solid color.
