Punch method (Main Control)

Builder Syntax	int Punch(int nValue, unsigned uStress, const TPoint &ptCenter, unsigned crFill, unsigned uFlags);
Delphi Syntax	Function Punch (nValue: L_INT; uStress: L_UINT; ptCenter: TPoint; crFill: COLORREF; uFlags: L_UINT): L_INT;
Overview	Refer to Applying Artistic Effects

Remarks

(Raster Pro and above toolkits only) Warps the bitmap by pinching it toward the center or expanding the bitmap away from its center.

This method will punch or pinch the bitmap 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.
