Parameter descriptions

FILE

Specifies the name of the GDB-supported image file containing the vector segment(s).

DBVS

Specifies the vector segment(s) to receive the output area and perimeter field.

Duplicate segments are not allowed.

Ranges of channels or segments can be specified with negative values. For example, {1,-4,10} is internally expanded to {1,2,3,4,10}. When you are not specifying a range in this way, only 48 numbers can be specified explicitly.

Details
