CImageView:SetCursorPos

The SetCursorPos method sets the center position of the image cursor in the CImageView.

Syntax

CImageView:SetCursorPos( x, y )

CImageView:SetCursorPos( CPoint )

where

x and y specify the target position in pixel coordinates, and may be numbers or strings.

CPoint is a CPoint object that speciies the target position.

Mira defines image coordinates for each axis as having pixel 1.0 located at the center of the first pixel. Thus, specifying the cursor position with x = 2.0 centers the image cursor in the middle of column 2.

Example

Assume that a CImageView object named V exists. The following script sets the image cursor to the center of the current image:

I = V:GetImage()	-- Get a CImage for the current displayed image
x = I:Cols() / 2	-- x, y refer to the center of the image
y = I:Rows() / 2
V:SetCursorPos(x,y)	-- move the image cursor to the image center
