CImageView:SetCursorHeight

The SetCursorHeight method sets the y range, or height, of the image cursor in the CImageView. This sets the number of rows, measured in pixels. The center position is not affected.

Syntax

bSuccess = CImageView:SetCursorHeight( nHeight )

where

nHeight is the cursor height, measured in pixels.

bSuccess is the returned success code. On success it is true, otherwise false.

Example

Assume that a CImageView object named V exists and refers to an image window. The following script sets the image cursor to a height of 50 pixels. Note that the center position is unchanged:

V:SetCursorExtent(100,800,100,300)	-- set a cursor size
V:SetCursorHeight( 50 )	-- set the image cursor
Printf("%lg:%lg, %lg:%lg", R:Get())	-- Result: [100:800, 175:225]
