isrgb - True for RGB image

Syntax

flag = isrgb(A)

isrgb has been removed.

Description

flag = isrgb(A) returns 1 if A is an RGB truecolor image and 0 otherwise.

isrgb uses these criteria to determine whether A is an RGB image:

• If A is of class double, all values must be in the range [0,1], and A must be m-by-n-by-3.

• If A is of class uint16 or uint8, A must be m-by-n-by-3.

Note   A four-dimensional array that contains multiple RGB images returns 0, not 1.

Class Support

A can be of class logical, uint8, uint16, or double.
