public:

   IntPtr hdc,
   RasterRegionXForm^ xform,
   int frameIndex
) 

Parameters

hdc

Windows device context handle where the image is displayed and where the frame is to appear.

xform

RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates.

frameIndex

Zero-index of the frame to display. Possible values are from 0 to MaxRegionFrameIndex. You can animate the region frame by cycling between these values.

If the region includes noncontiguous shapes, each shape is outlined. The outline, itself, is inside the region.

Before calling this method, create a RasterRegionXForm object and set its values, which LEADTOOLS uses to translate between device context coordinates and image coordinates.

This method is designed to produce an animated frame, which you can implement by calling the method with a timer event that cycles through the possible frame types.

For more information, refer to Creating a Region and Working with the Existing Region.
