CRect:Set

The Set method initializes the 4 properties of the CRect to specific values.

Syntax

CRect:Set( xmin, xmax, ymin, ymax )

• nXmin, nXmax, nYmin, nYmax are numbers that specify the rectangle limits in terms of pixel coordinates. They may be positive or negative.

CRect:Set( CRect )

• The CRect is copied to the properties of the current CRect.

CRect:Set( CImage )

• The column and row dimensions of the CImage are copied to the rectangle so that the rectangle extends from 1 to CImage:Cols(), and 1 to CImage:Rows().

Example

The following script initializes the 4 dimensions of the CRect to xmin=100, xmax=200, ymin=40.5, ymax=300.25. Note the order in which the values are passed, with both x values first, followed by both y values:
