Utilities | iOS Document Scanner

Besides the scanning modules, Scanbot SDK also contains some utility classes that can reduce your workload, hence making your life easier:

Zoom- and scrollable image view (SBSDKZoomingImageScrollView)​

  • You can use it as a direct UIImageView replacement.
  • You can zoom in to the image, scroll around, and when you zoom out, the image is centered within the view.
  • You can add a transparent overlay that will act like a HUD above the image view.
  • You can specify the margins that the image should maintain when zoomed out.

Image Storages (SBSDKIndexedImageStorage, SBSDKKeyedImageStorage)​

  • SBSDKIndexedImageStorage and SBSDKKeyedImageStorage are thread-safe and persistent storage for images.
  • They can be used to store and retrieve images in an array-fashioned style (indexed) or dictionary-fashioned style (keyed) to and from the device disk.
  • Both allow the usage of an encrypter which encrypts the data when writing it to the disk and decrypts the data when reading it from the disk.
  • These classes conform to the SBSDKImageStoring protocol. Custom image storage can be implemented and used within the Scanbot SDK by conforming to this protocol.
