This method calculates the distance betweent two points.
Parameters
pt1
Coordinates of the first point
pt2
Coordinates of the second point
unit
Units as LengthUnit
dpi
Dpi of the image to be measured (integer value)
Return Value
The distance between the two points (double value)
Explanation
The CalculateDistance method calculates the distance betweent two points. the result will be returned in values defined by the units parameter. When unit is set to LengthUnit.mm or LengthUnit.Inch, the value set for dpi is also taken into account. If unit is set to LengthUnit.None, the result is the same as for LengthUnit.Pixel.
You can also use the MouseUpImage event or the annotation object's SelectedObjectDrawPoints property to determine the distance between two clicked points on the image displayed in the ImageKit control.
