Strict disallows implicit conversions from Drawing.Point' to 'Drawing.Size

Trying to get a grasp on skinning. Works fine with strict off how ever i do understand the implicit conversion but can't for the life of me solve it.


Error 1 Overload resolution failed because no accessible '-' can be called with these arguments:
'Public Shared Operator -(pt As System.Drawing.Point, sz As System.Drawing.Size) As System.Drawing.Point': Option Strict On disallows implicit conversions from 'System.Drawing.Point' to 'System.Drawing.Size'
