public:
void AddRoundRectangleToRegion(
Leadtools.RasterRegionXForm^ xform,
Leadtools.LeadRect rc,
Leadtools.LeadSize ellipse,
Leadtools.RasterRegionCombineMode combineMode
)
xform
RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.
rc
A LeadRect that specifies the bounding rectangle of the region.
ellipse
Specifies the width and height of the ellipse that describes the arc of the rounded corners.
combineMode
The action to take regarding the existing image region, if one is defined.
To update an existing region, you specify how the new region is to be combined with the existing one using the combineMode parameter. For more information, refer to RasterRegionCombineMode.
For more information, refer to Creating a Region.
For more information, refer to Saving A Region.
For more information, refer to Working with the Existing Region.
This example will load an image, adds a round rectangle region to it, run the InvertCommand to show the affected area before saving the image back to disk.
