Name Type Description
rect CoreControls.Math.Rect the new bounding rectangle
Inherited From:

setRectWithNormalization(rect)

Sets the size and location of the annotation's bounding rectangle. Use this method instead of resize when only the x, y, width and height needs to be modified. Use setRectWithNormalization instead of setRect if you want to reverse any wrong-way-round coordinates instead of ignoring them.
Parameters:
Name Type Description
rect CoreControls.Math.Rect the new bounding rectangle
