>1. 
```objc
@property(nonatomic, assign, readonly) NSInteger rows;
```
2. 
```swift
var rows: Int { get }
```

### columns

The number of columns of the Data Matrix barcode, indicating how many columns of data modules it contains.

<div class="sample-code-prefix"></div>

>
>1. 
```objc
@property(nonatomic, assign, readonly) NSInteger columns;
```
2. 
```swift
var columns: Int { get }
```

### dataRegionRows

The number of rows of the data region within the Data Matrix barcode. Data regions are subdivisions of a Data Matrix barcode where data is stored.

>1. 
```objc
@property(nonatomic, assign, readonly) NSInteger dataRegionRows;
```
2. 
```swift
var dataRegionRows: Int { get }
```

### dataRegionColumns

The number of columns of the data region within the Data Matrix barcode. Data regions are subdivisions of a Data Matrix barcode where data is stored.

>1. 
```objc
@property(nonatomic, assign, readonly) NSInteger dataRegionColumns;
```
2. 
```swift
var dataRegionColumns: Int { get }
```

### dataRegionNumber

The number of data regions in the Data Matrix barcode. Data Matrix barcodes can have multiple data regions for storing data redundantly or for error correction purposes.
