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.
|
bResult = CImageView:SetCursorHeight( nHeight ) |
ThenHeight value specifies the cursor height, measured
in pixels.
On success, the
method returns true.
On failure,
false is
returned.
Assume that a CImageView object named V exists and wraps an image window. The following script fragment 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] |
