# mmisbinary
Check for binary image

## Synopsis

bool = mmisbinary( f )

Implemented in Python.

### Input

f | Image

### Output

bool | Boolean

## Description

mmisbinary returns `TRUE(1)` if the datatype of the input image is binary. A binary image has just the values 0 and 1.

## Examples

    >>> a=uint8([0, 1, 0, 1])

    >>> print mmisbinary(a)

    0.0

    >>> b=(a)

    >>> print mmisbinary(b)

    0.0

## Source Code

    def mmisbinary(f):
        bool = type(f) is type(mmbinary([1]))
        if bool:
           bool = f.typecode() == '1'
        return bool
