CImageView:SetCursorExtent

The SetCursorExtent method sets the extent of the image cursor in the CImageView. This differs from SetCursorRect in the argument list.

Syntax

bResult = CImageView:SetCursorExtent( xmin, xmax, ymin, ymax )

The xmin, xmax, ymin, and ymax values specify the cursor bounds, measured in pixel coordinates.

On success, the method returns true.
On failure, false is returned.

Example

Assume that a CImageView object named V exists and refers to an image window. The following script fragment sets the image cursor to an x-range of 50:150 and a y-range of 100:300. Notice that both values returned by R:Size() can be printed since it is the last parameter in the Printf argument list:

V:SetCursorExtent(50,150,100,300)	-- set the image cursor
R = V:GetCursorRect()	-- fetch the image cursor rectangle
Printf("W=%lg, H=%lg", R:Size())	-- Result: W=100, H=200
