@protocol DCEPhotoListener <NSObject>

photoOutputCallback

The callback method for user to receive the captured photo. User can complete the method by adding code to execute with the capture image.

- (void)photoOutputCallback:(NSData *)jpegBytes;

Parameters

jpegBytes The byte data of the captured image.

Code Snippet

• Objective-C
• Swift

1. @interface ViewController ()<DCEPhotoListener>
   - (void)configurationDCE(){
      // When you trigger takePhote method, the library firstly capture a photo
      // When the photo is captured and stored in memory, it will be processed by DBR
      [_dce takePhoto:self]
   }
   - (void)photoOutputCallback:(NSData *)jpegBytes{
      // Add your code to execute when photo is captured.
      // For example, you can use Dynamsoft Barcode Reader (DBR) to decode the byte image.
      NSArray<iTextResult*> *barcodeResults = [_dbr decodeFileInMemory:jpegBytes error:nil];
   }
   

2. class ViewController: UIViewController, DCEPhotoListener {
      func configurationDCE(){
         // When you trigger takePhote method, the library firstly capture a photo
         // When the photo is captured and stored in memory, it will be processed by DBR
         dce.takePhoto()
      }
      func photoOutputCallback(_ jpegByte: Data){
         // Add your code to execute when photo is captured.
         // For example, you can use Dynamsoft Barcode Reader (DBR) to decode the byte image.
         let barcodeResults = try? dbr.decodeFileInMemory(jpegByte)
      }
   }
