public PointF convertPoint(CoordinateType sourceType, 
                           CoordinateType destType, 
                           PointF point)

 function Leadtools.Controls.ImageViewer.ConvertPoint(  
   sourceType , 
   destinationType , 
   point  
)

Parameters

sourceType
The source coordinate type.

destinationType
The destination coordinate type.

point
The point to be converted.

Return Value

The converted point, in the destination coordinate type.

Remarks

Use this method to convert a point from control to image coordinates or back. This method will simply multiply the point by the transformation matrix (Transform) when converting from image to control coordinates and by the inverse of this matrix when converting from control to image coordinate.

If sourceType has the same value as destinationType, then this method will return a value equal to point.
