CImageView:SetCursorPos

The SetCursorPos method sets the center position of the image cursor in the CImageView. The coordinates must be in Pixel Coordinate Definition.

Syntax

CImageView:SetCursorPos( x, y )

Remarks

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
