  HITRESULT_TRANSPARENT = 1, 
  HITRESULT_CLOSE = 2,

Elements

  • HITRESULT_OUTSIDE
    The specified location is outside the object and not close to the object.
  • HITRESULT_TRANSPARENT
    The specified location is within the bounds of the object, but not close to the image. For example, a point in the middle of a transparent circle could be HITRESULT_TRANSPARENT.
  • HITRESULT_CLOSE
    The specified location is inside the object or is outside the object but is close enough to the object to be considered inside. Small, thin, or detailed objects can use this value. Even if a point is outside the bounding rectangle of an object it can still be close. This value is needed for hitting small objects.
  • HITRESULT_HIT
    The specified location is within the image of the object.

OS Versions: Windows CE 3.0 and later.
