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

bResult = CImageView:SetCursorHeight( nHeight )

bullet.gif    ThenHeight value specifies the cursor height, measured in pixels.

bullet.gif    On success, the method returns true.

bullet.gif    On failure, false is returned.

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:SetCursorHeight( 50 )

-- set the image cursor height

R = V:GetCursorRect()

-- return the cursor rectangle as a CRect

Printf("%lg, %lg", R.ymin, R.ymax)

-- Result: [100:800, 175:225]
