The bounding box for the annotation appearance, that you need to follow, is defined by values x, y, w, h, where x and y define the coordinates of the top-left corner of the box as x = (Annot.Left - Annot.Width) / 2, y = (Annot.Top - Annot.Height) / 2, w defines the width of the box as w = Annot.Width and y defines the height of the box as y = Annot.Height.

The measurement unit used for specified dimensions and sizes is expressed in inches. The rotation, if any, is handled by the component, which automatically sets the required transformation.
