Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type Description
DomainError Input image must have pixel type different from Int8 and Int32 in cvScharr.
DomainError Input image must not be empty in cvScharr.
