[Insight-users] Question about ItkAndImageFilter

[Bill Lorensen]

XueQuan,

The AndImageFilter (and other logical filters) require types that are of
integral type. From the comments in itkAndImageFilter.h:
 *
 * Since the logical AND operation is only defined in C++ for integer
 * types, the images passed to this filter must comply with the requirement
 * of using integer pixel type.

Unfortunately, the error message is a bit cryptic. If you turn
ITK_USE_CONCEPT_CHECKING ON (it is an advanced cmake option), you will see a
better error message.

So, you should cast your input to an integral type before doing the and.

Bill
