SBSDKTextOrientationRecognizer

@interface SBSDKTextOrientationRecognizer : NSObject

A class, that determines orientation of text on the image. Initialization of this class can be resourse-intensive, so in case you want to analyze multiple images, it is better to create instance of SBSDKTextOrientationRecognizer once and use it multiple times.

  • Synchronously recognizes text orientation on the image.

    Declaration

    Objective-C

    Swift

    func textOrientation(for image: UIImage!) -> SBSDKTextOrientation

    Parameters

    image
