Can someone explain the usage of the setgradient function in the IGraphicsPort interface?

[lyj2871]

In the IGraphicsPort interface, there is a virtual function:

virtual void setgradient(AGMGradient *agmGrad, const PMMatrix& grMatrix,
                         const PMReal &xOrig, const PMReal &yOrig,
                         const PMReal &len, const PMReal &ang,
                         const PMReal &hiliteLen, const PMReal &hiliteAng) = 0;

I couldn't find a precise definition of the first parameter, AGMGradient *agmGrad. I assume that this requires a pointer to some other object, but how should this object be created? What exactly needs to be passed in?

AGM is an old library exposed via wrappers ony, the actual AGM* structures remain opaque / forward declarations, similar to CT* structures. Related methods are in a private (no headers provided) gradient utils class.

Please file a feature request in developer prerelease to expose the header.

I should have checked the SDK first. Above was from 2018 when I last tried to examine such an object.

Gradients are a rendering object similar to color swatches, tint etc., applying such a rendering object should do.

I'd first try IGradientFillInstall though.

Could  you share some sample code? Thanks.
