Return true for an indexed image
Syntax
flag = isind(A)
Description
flag = isind(A) returns 1 if A is an indexed image and 0 otherwise.
isind uses these criteria to determine if A is an indexed image:
A is of class double, all values in A must be integers greater than or equal to 1, and the number of dimensions of A must be 2.
A is of class uint8, its logical flag must be off, and the number of dimensions of A must be 2.
A is of class uint16, the number of dimensions of A must be 2.
Class Support
A can be of class uint8, uint16, or double.
