IsSameAs

The IsSameAs method returns a Boolean value that indicates whether this shape is identical to the specified shape.

ODBoolean IsSameAs (in ODShape compareShape);

compareShape

A reference to the shape to be compared with this shape.

return value

kODTrue if the shapes are equivalent, otherwise kODFalse.

DISCUSSION

If both shapes have polygonal representations, they are equivalent if they consist of the same contours. The order of the contours does not matter. Each of the corresponding contours in the two polygons must have their vertices listed in the same direction (clockwise or counterclockwise).

If this shape is described only by a platform shape (such as a region), then the platform graphics system is used to determine equality; typically, the compareShape parameter must be a platform shape of the same type.

EXCEPTIONS

kODErrOutOfMemory

There is not enough memory to compare the two shapes.
