CRect:Round

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()

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 to integer values
Printf("%lg %lg, %lg %lg", R:Get() )	-- result: 383 502, 603 555
