Mat &operator =(const Mat &other)

Idiom to treat the template like a Mat. Set the result of m() equal to other.

function definition:

inline Mat &operator=(const Mat &other)

parameters:

Parameter Type Description

other const Mat & Mat to overwrite value of m
output: (Mat &) Returns a reference to the updated Mat

bool isNull() const

Check if the template is NULL.

function definition:
```
inline bool isNull() const
```
parameters: NONE
output: (bool) Returns true if the template is empty or if m has no data.

example:

Template t;
t.isNull(); // returns true

t.append(Mat());
t.isNull(); // returns true

t.append(Mat::ones(1, 1, CV_8U));
t.isNull(); // returns false

void merge(const Template &other)

Append the contents of another template. The files are appended using append.

function definition:

inline void merge(const Template &other)

parameters:

Parameter Type Description

other const Template & Template to be merged
output: (void)

example:

Template t1("picture1.jpg"), t2("picture2.jpg");
Mat m1, m2;

t1.append(m1);
t2.append(m2);

t1.merge(t2);

t1.file; // returns picture1.jpg;picture2.jpg[seperator=;]
t1; // returns [m1, m2]

size_t bytes() const

Get the total number of bytes in the template

function definition:
```
size_t bytes() const
```
parameters: None
output: (int) Returns the sum of the bytes in each Mat in the Template

example:

Template t;

Mat m1 = Mat::ones(1, 1, CV_8U); // 1 byte
Mat m2 = Mat::ones(2, 2, CV_8U); // 4 bytes
Mat m3 = Mat::ones(3, 3, CV_8U); // 9 bytes

t << m1 << m2 << m3;

t.bytes(); // returns 14

Template clone() const

Clone the template

function definition:
```
Template clone() const
```
parameters: NONE
output: (Template) Returns a new Template with copies of the file and each Mat that was in the original.

example:

Template t1("picture.jpg");
t1.append(Mat::ones(1, 1, CV_8U));

Template t2 = t1.clone();

t2.file; // returns "picture.jpg"
t2; // returns ["1"]
