SBSDKUIBarcodeImageStorage

@interface SBSDKUIBarcodeImageStorage : NSObject

A class to store and remove barcode images from SBSDKUIBarcodeScannerViewController.

  • If file format is set to JPEG, this property holds the compression quality of the stored images. Values must be between 0 (high compression, small file size, bad quality) and 100 (no compression, huge file size, good image quality). Read-only. Defaults to 80.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSInteger writingJpegImageCompressionQuality;

    Swift

    var writingJpegImageCompressionQuality: Int { get }

  • File format of the stored images. Read-only. Defaults to JPEG.

    Declaration

    Objective-C

    @property (nonatomic, readonly) SBSDKImageFileFormat writingImageFileFormat;

    Swift

    var writingImageFileFormat: SBSDKImageFileFormat { get }

  • The default instance of this class. *
