Example

The following script returns the values of the image cursor rectangle and then rounds them to the nearest integer pixel coordinates. Assume that a CImageView V is attached to an image window. Note that the CImage I and CRect R do not need to be created separately, as they are created by the methods that return them as a value.

I = V:GetImage()

-- create a CImage for the displayed image

R = V:GetCursorRect()

-- Create a CRect for the cursor rectangle

Printf("%lg %lg %lg %lg", R:Get() )

-- result: 383.43 502.14 603.43 554.83

R:Round()

-- round down to integer values

Printf("%lg %lg %lg %lg", R:Get() )

-- result: 383 502 603 555
