### rows

The number of rows in the PDF417 barcode, indicating how many rows of modules it contains.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
@property(nonatomic, assign, readonly) NSInteger rows;
```
2. 
```swift
var rows: Int { get }
```

### codewords

The codewords of the PDF417 barcode.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
@property (nonatomic, readonly, copy, nullable) NSArray<NSNumber *> *codewords;
```
2. 
```swift
var codewords: [NSNumber]? { get }
```

### columns

The number of columns in the PDF417 barcode, indicating how many columns of modules it contains.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
@property(nonatomic, assign, readonly) NSInteger columns;
```
2. 
```swift
var columns: Int { get }
```

### errorCorrectionLevel

The error correction level of the PDF417 code.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
@property(nonatomic, assign, readonly) NSInteger errorCorrectionLevel;
```
2. 
```swift
var errorCorrectionLevel: Int { get }
```

### hasLeftRowIndicator

Indicates whether the left row indicator of the PDF417 code exists. If the value is 1, the PDF417 barcode has the left row indicator. Otherwise, it does not have the left row indicator. The left row indicator is used to denote the start of a new row in the barcode.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
@property(nonatomic, assign, readonly) BOOL hasLeftRowIndicator;
```
2. 
```swift
var hasLeftRowIndicator: Bool { get }
```

### hasRightRowIndicator

Indicates whether the right row indicator of the PDF417 code exists. If the value is 1, the PDF417 barcode has the right row indicator. Otherwise, it does not have the right row indicator. The right row indicator is used to denote the end of a row in the barcode.

<div class="sample-code-prefix"></div>
>- Objective-C
>- Swift
>
>1. 
```objc
@property(nonatomic, assign, readonly) BOOL hasRightRowIndicator;
```
2. 
```swift
var hasRightRowIndicator: Bool { get }
```
