Swirl method (Main Control)

Builder Syntax	int Swirl(int nAngle, const TPoint &ptCenter);
Delphi Syntax	Function Swirl (nAngle: L_INT; ptCenter: TPoint ): L_INT;
Overview	Refer to Applying Artistic Effects

Remarks

(Raster Pro and above toolkits only) Spins the image according to the rotation angle to produce a swirl pattern.

The method swirls the image around the specified ptCenter. The center point must be defined inside the bitmap, or inside the region, if the bitmap has a region. If the bitmap has a region, the effect will be applied on the region only.

This method supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.

This method does not support signed data images. It Returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this method.
