The Round method rounds all 4 rectangle limits to the nearest integer value. For example xmax=100.54 becomes xmax=101 , and xmax=100.49 becomes xmax=100. This method uses the Round function.

Syntax

CRect:Round()

This method has no arguments and no return value.

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
