CDC::SelectClipPath

  • Article

BOOLSelectClipPath(intnMode**);**

Return Value

Nonzero if the function is successful; otherwise 0.

Parameters

nMode

Specifies the way to use the path. The following values are allowed:

  • RGN_AND   The new clipping region includes the intersection (overlapping areas) of the current clipping region and the current path.

  • RGN_COPY   The new clipping region is the current path.

  • RGN_DIFF   The new clipping region includes the areas of the current clipping region, and those of the current path are excluded.

  • RGN_OR   The new clipping region includes the union (combined areas) of the current clipping region and the current path.

  • RGN_XOR   The new clipping region includes the union of the current clipping region and the current path, but without the overlapping areas.

Remarks

Selects the current path as a clipping region for the device context, combining the new region with any existing clipping region by using the specified mode. The device context identified must contain a closed path.
