SDK

Adding the SDK to your project

To add our SDK to your own application, you should add it to the build process of your application. Currently we support doing this using CocoaPods or Carthage.

To add the repository to your project, open the Podfile, if it does not exists, first run pod init in the root of your project with Xcode closed.
Edit the target part of your application in the Podfile, so that it contains the following: 

                    
pod 'Klippa-Scanner', podspec: 'https://custom-ocr.klippa.com/sdk/ios/specrepo/ExampleUsername/ExamplePassword/KlippaScanner/latest.podspec'

The full Podfile might look like this now: 

                    
# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'TestScanner' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for TestScanner
  pod 'Klippa-Scanner', podspec: 'https://custom-ocr.klippa.com/sdk/ios/specrepo/ExampleUsername/ExamplePassword/KlippaScanner/latest.podspec'

end

When you run pod install now, it should download our library as dependency, and with that all dependencies of our library.
Note: this code always uses the latest version, you can also use a specific version to make sure the SDK won't update without your knowledge.

To add the repository to your project, open the Cartfile, if it does not exists, create a Cartfile alongside your .xcodeproj or .xcworkspace.
Add the following to your Cartfile: 

                    
binary "https://custom-ocr.klippa.com/sdk/ios/carthage/ExampleUsername/ExamplePassword/KlippaScanner.json"

When you run carthage update now, it should download our library as dependency, and with that all dependencies of our library.
Note: this code always uses the latest version, you can also use a specific version to make sure the SDK won't update without your knowledge.

Starting the Klippa Scanner

As of KlippaScanner SDK Version 1.0.0 the implementation has changed. If you are using an 0.5.4 or earlier use the button below to switch to the original documentation.

To start the scanner, import our package:

                    
// Add to the top of your file
import KlippaScanner

In the controller that you want to launch the scanner, implement the KlippaScannerDelegate. 

                    
// Add to the top of your file
import KlippaScanner

// Your class definition should look like this.
final class ExampleScannerViewController: UIViewController, KlippaScannerDelegate {

    // ... Rest of your controller code.

    // Call this from a button
    func startKlippaScanner() {
        let license = "{your-license}"

        let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        builder.startScanner(context: self)

        //        Or
        //        let viewController = builder.build()
        //        present(viewController, animated: true)
    }

    func klippaScannerDidFailWithError(error: Error) {
        switch error {
        case let licenseError as KlippaScannerLicenseError:
            print("Got licensing error from SDK: \(licenseError.localizedDescription)")
        default:
            print(error)
        }
    }

    func klippaScannerDidFinishScanningWithResult(result: KlippaScannerResult) {
        // Handle scan results here.
        print("didFinishScanningWithResult")
        print("multipleDocumentsModeEnabled \(result.multipleDocumentsModeEnabled)")
        print("Scanned \(result.images.count) images")
    }

    func klippaScannerDidCancel() {
        print("Scanner canceled")
    }

    // ... Rest of your controller code.
}

In the place where you want to start the scanner, for example after a button click, call the startKlippaScanner method:

                    
startKlippaScanner()
                    
                
                    
// Add to the top of your file
import KlippaScanner

Then init the scanner options inside your launch method, the license is the only required option:

                    
KlippaScanner.setup.license = "replace-with-received-license"

In the controller that you want to launch the scanner, implement the ImageScannerControllerDelegate: 

                    
// Add to the top of your file
import KlippaScanner

// Your class definition should look like this.
final class ExampleScannerViewController: UIViewController, ImageScannerControllerDelegate {

    // ... Rest of your controller code.

    func startScanner() {
        let scannerViewController = ImageScannerController()
        scannerViewController.imageScannerDelegate = self
        scannerViewController.modalPresentationStyle = .fullScreen
        present(scannerViewController, animated: false)
    }

    func imageScannerController(_ scanner: ImageScannerController, didFailWithError error: Error) {
        switch error {
        case let licenseError as LicenseError:
            print("Got licensing error from SDK: \(licenseError.localizedDescription)")
        default:
            print(error)
        }
    }

    func imageScannerController(_ scanner: ImageScannerController, didFinishScanningWithResult result: ImageScannerResult) {
        // Handle scan results here.
        print("didFinishScanningWithResult");
        print("multipleDocumentsModeEnabled \(result.multipleDocumentsModeEnabled)")
        print("Scanned \(result.images.count) images")
    }

    func imageScannerControllerDidCancel(_ scanner: ImageScannerController) {
        scanner.dismiss(animated: true, completion: nil)
    }

    // ... Rest of your controller code.
}

In the place where you want to start the scanner, for example after a button click, call the startScanner method:

                    
startScanner()

Customizing the scanner

The SDK has a few customizing settings, the following methods are available:

Customizing the colors

Note: when setting the colors the values should be a UIColor.

                    
let colors = KlippaColors(
    // The primary color of the interface. This is used for the app bar.
    primaryColor: .green,
    // The accent color of the interface. This is used for control elements.
    accentColor: .orange,
    // The overlay color (when using document detection).
    overlayColor: .gray,
    // The color of the background of the warning message.
    warningBackgroundColor: .red,
    // The color of the text of the warning message.
    warningTextColor: .white,
    // The overlay color (when using document detection).
    overlayColorAlpha: 0.75,
    // The color of the menu icons when they are enabled.
    iconEnabledColor: .white,
    // The color of the menu icons when they are disabled.
    iconDisabledColor: .gray,
    // The color of the menu icons of the screen where you can review/edit the images.
    reviewIconColor: .white,
    // What the default color conversion will be (grayscale, original, enhanced).
    defaultImageColor: .original)

// Call this from a button
func startKlippaScanner() {
    let license = "{your-license}"
    let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        .klippaColors(colors)
    builder.startScanner(context: self)
}
                    
                
    
// The primary color of the interface, should be a UIColor.
KlippaScanner.setup.primaryColor = UIColor(red: 0.153, green: 0.733, blue: 0.373, alpha: 1.00)

    moveCloserMessage: "Move closer to the document",
    // The warning message when the camera result is too bright.
    imageTooBrightMessage: "The image is too bright",
    // The warning message when the camera result is too dark.

    // The warning message when the camera preview has too much motion to be able to automatically take a photo.
    imageMovingMessage: "Camera is moving too much",
    // The message to display when the limit has been reached.
    imageLimitReachedMessage: "You have reached the limit",
    // The warning message when device is held in landscape mode.
    orientationWarningMessage: "Hold your phone in portrait mode",
    // After capture, show a checkmark preview with this success message, instead of a preview of the image.
    successMessage: "success",
    // The confirmation message shown when the cancel button is pressed on the review screen.
    cancelConfirmationMessage: "Delete photos and exit scanner?")

// Call this from a button
func startKlippaScanner() {
    let license = "{your-license}"
    let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        .klippaMessages(messages)
    builder.startScanner(context: self)
}
    

    
// The warning message when someone should move closer to a document, should be a string.
KlippaScanner.setup.moveCloserMessage = "Move closer to the document"

// The warning message when the camera preview has too much motion to be able to automatically take a photo.
KlippaScanner.setup.imageMovingMessage = "Too much movement"

// The warning message when the camera result is too bright.
KlippaScanner.setup.imageTooBrightMessage = "The image is too bright"

// The warning message when the camera result is too dark.
KlippaScanner.setup.imageTooDarkMessage = "The image is too dark"

// Users receive an orientation warning when device is not held in portrait mode, text can be set with:
KlippaScanner.setup.orientationWarningMessage = "Hold your phone in portrait mode"

// Ability to limit amount of pictures that can be taken and set a message once the limit has been reached.
KlippaScanner.setup.set(imageLimitReachedMessage: "Limit reached", imageLimit: 1)

// After capture, show a checkmark preview with this success message, instead of a preview of the image.
KlippaScanner.setup.set(successMessage: "Success!", successPreviewDuration: 0.3)

Customizing text in buttons

                    
let buttonTexts = KlippaButtonTexts(
    // The text inside of the delete button.
    deleteButtonText: "Delete",

    retakeButtonText: "Retake",
    // The text inside of the cancel button.
    cancelButtonText: "Cancel",
    // The text inside of the cancel confirmation alert, confirming to cancel the scanner without a result.
    cancelAndDeleteImagesButtonText: "Delete photos and exit",
    // Tapping on the image color-changing button prompts an alert to confirm your action.
    // Texts can be set with:

    let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        .klippaButtonTexts(buttonTexts)
    builder.startScanner(context: self)
}
                    
                
    
// Deleting an image prompts an alert to confirm your action. Texts can be set with:
KlippaScanner.setup.set(deleteButtonText: "Delete", retakeButtonText: "Retake", cancelButtonText: "Cancel")

// Ability to cancel the scanner completely on the review screen by pressing cancel, texts can be set with:
KlippaScanner.setup.set(cancelConfirmationMessage: "Delete photos and exit scanner?", cancelAndDeleteImagesButtonText:

// Tapping on the image color-changing button prompts an alert to confirm your action. Texts can be set with:
KlippaScanner.setup.set(imageColorOriginalText: "Original", imageColorGrayscaleText: "Grayscale",
imageColorEnhancedText: "Enhanced")

Customizing the menu icons

                    
let menu = KlippaMenu(
    // Whether the crop mode (auto edge detection) should be enabled by default.
    isCropEnabled: false,
    // Whether to show the icon to enable "multi-document-mode"
    allowMultipleDocumentsMode: false,
    // Whether the "multi-document-mode" should be enabled by default.

    // Whether the camera has a view finder overlay (a helper grid so the user knows where the document should be), should be a Boolean.
    isViewFinderEnabled: false)

// Call this from a button
func startKlippaScanner() {
    let license = "{your-license}"
    let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        .klippaMenu(menu)
    builder.startScanner(context: self)
}
                    
                
    
// Whether to show the icon to enable "multi-document-mode"
KlippaScanner.setup.set(allowMultipleDocumentsMode: true)

// Whether the "multi-document-mode" should be enabled by default.
KlippaScanner.setup.set(isMultipleDocumentsModeEnabled: true)

// Whether the crop mode (auto edge detection) should be enabled by default.
KlippaScanner.setup.set(cropEnabled: true)

// Whether going to the review screen automatically once the image limit has been reached. Default false.
KlippaScanner.setup.shouldGoToReviewScreenWhenImageLimitReached = true

// Whether the camera has a view finder overlay (a helper grid so the user knows where the document should be), should
be a Boolean.
KlippaScanner.setup.isViewFinderEnabled = true

// Whether the camera automatically saves the images to the camera roll. Default true. (iOS version 0.4.2 and up only)
KlippaScanner.setup.storeImagesToCameraRoll = true

// Ability to hide timer button.
KlippaScanner.setup.allowTimer = false

// If you would like to enable automatic capturing of images.
KlippaScanner.setup.isTimerEnabled = true


// Ability to hide top navigation bar buttons.
KlippaScanner.setup.set(userCanRotateImage: true, userCanCropManually: true, userCanChangeColorSetting: true)

Customizing the image attributes

    
let imageAttributes = KlippaImageAttributes(

    imageLimit: 2,
    // Define the max resolution of the output file.
    // It’s possible to set only one of these values.
    // We will make sure the picture fits in the given resolution.
    // We will also keep the aspect ratio of the image. Default is max resolution of camera.
    imageMaxWidth: 3000,
    imageMaxHeight: 3000,
    // Set the output quality (between 0-100) of the jpg encoder. Default is 100.
    imageMaxQuality: 95,
    // The threshold sensitive the motion detection is. (lower value is higher sensitivity, default 200).
    imageMovingSensitivity: 200,
    // To add extra horizontal and / or vertical padding to the cropped image.
    cropPadding: CGSize(width: 100, height: 100),
    // Whether the camera automatically saves the images to the camera roll. Default true.
    storeImagesToCameraRoll: false)

// Call this from a button
func startKlippaScanner() {
    let license = "{your-license}"
    let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        .klippaImageAttributes(imageAttributes)
    builder.startScanner(context: self)
}
    

    
// Define the max resolution of the output file. It’s possible to set only one of these values. We will make sure the
picture fits in the given resolution. We will also keep the aspect ratio of the image. Default is max resolution of
camera.
KlippaScanner.setup.imageMaxWidth = 1920
KlippaScanner.setup.imageMaxHeight = 1080

// Set the output quality (between 0-100) of the jpg encoder. Default is 100.
KlippaScanner.setup.imageMaxQuality = 95

// To add extra horizontal and / or vertical padding to the cropped image.
KlippaScanner.setup.set(cropPadding: CGSize(width: 100, height: 100))

// The threshold sensitive the motion detection is. (lower value is higher sensitivity, default 200).
KlippaScanner.setup.imageMovingSensitivity = 200

Customizing the shutter button

    
let shutterButton = KlippaShutterButton(
    // Whether to allow the shutter button. (If false the shutter button is greyed out)
    allowShutterButton: true,
    // Whether to hide the shutter button. (Only works if allowShutterButton is false)
    hideShutterButton: false)

// Call this from a button
func startKlippaScanner() {
    let license = "{your-license}"
    let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        .klippaShutterbutton(shutterButton)
    builder.startScanner(context: self)
}
    

    
// Ability to disable/hide the shutter button (only works when a model is supplied as well).
KlippaScanner.setup.set(allowShutterButton: true, hideShutterButton: false)

Customizing the timers

    
let durations = KlippaDurations(
    // The amount of seconds the preview should be visible for, should be a float.
    previewDuration: 2.0,
    // The duration of the timer. (Only works if timer is enabled)
    timerDuration: 1.0,
    // Whether to show a success checkmark and how long.
    successPreviewDuration: 0.5)

// Call this from a button
func startKlippaScanner() {
    let license = "{your-license}"
    let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        .klippaDurations(durations)
    builder.startScanner(context: self)
}
    

    
// The amount of seconds the preview should be visible for, should be a float.
KlippaScanner.setup.previewDuration = 1.0

//The amount of seconds the timer requires before automatically taking photo.
KlippaScanner.setup.timerDuration = 0.5

Calling the OCR API

It's possible to use the results of the scanner with the OCR API.

To use it, generate a Public API key with our API through your own backend, this makes sure your API key won't be leaked and/or abused.

Edit your Podfile file, so that it contains the following: 

                    
pod 'Klippa-OCR-API', podspec: 'https://custom-ocr.klippa.com/sdk/ios/specrepo/ExampleUsername/ExamplePassword/KlippaOCRAPI/latest.podspec'

If you are using Carthage, add the folowing to your Cartfile: 

                    
binary "https://custom-ocr.klippa.com/sdk/ios/carthage/ExampleUsername/ExamplePassword/KlippaOCRAPI.json"

You then have the possibility to call the OCR API client and run it on the images of the scanner.
The following example runs the OCR on every image and then shows the total amount. 

                

import UIKit
import KlippaScanner
import KlippaOCRAPI

final class ViewController: UIViewController, KlippaScannerDelegate {

    private var loadedScanner = false
    private var totalAmount: Float64 = 0
    private var vSpinner : UIView?

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        if (!loadedScanner) {
            loadedScanner = true
            startKlippaScanner()
        }
    }

    func startKlippaScanner() {
        let license = "{your-license}"

        let builder = KlippaScannerBuilder(builderDelegate: self, license: license)
        builder.startScanner(context: self)

        //        Or
        //        let viewController = builder.build()
        //        present(viewController, animated: true)
    }

0.4.8

Added

  • arm64 build for simulator to add support for M1 Macs. Please note that this only work in XCFrameworks (CocoaPods), and not in the fat framework, since you can only have one arm64 binary, and the device binaries already come with an arm64 binary.

0.4.7

Fixed

  • When scanning with a model the scanner no longer requires you to supply the Bundle.

0.4.6

Added

  • Ability to disable/hide the shutter button. KlippaScanner.setup.set(allowShutterButton: false, hideShutterButton: false)
  • Ability to adjust the sensitivity of the motion detection, lower values give higher sensitivity. KlippaScanner.setup.set(imageMovingSensitivity: 200)

0.4.2

Fixed

  • Issue where scanner failed to reinitialize.
  • Issue where storing enhanced images sometimes caused memory to run out.

Added

  • Ability to disable saving to camera roll with following method KlippaScanner.setup.set(storeImagesToCameraRoll: false).

0.4.1

Fixed

  • Issue where images did not load in React Native.
  • Issue where path was not returned correctly from scanner in React Native.

Added

  • Helper method retrieve(path: "pathToImage", from directory: .documents, as type: UIImage.self) to retrieve image from provided path.

0.4.0

Fixed

  • Important: Scanner now only returns a path to image in documents instead of also a UIImage (see next bullet point for reasoning).
  • Taken images are now no longer stored in device memory but in temporary storage.
  • Fixed multiple memory leaks.

0.3.4

Fixed

  • Issue related to implementing the SDK directly in a Swift project.

0.3.3

Fixed

  • Added default extension for model and labelmap file.

0.3.2

Fixed

  • Added default value for crop padding: CGSize(0, 0)

0.3.1

Fixed

  • Fixed the overlay color not being correctly restored.

0.3.0

Changed

  • Added the ability to recognize custom objects (instead of documents) using a trained TensorFlow Lite model. Klippa can train these custom models for whatever you like to capture using the KlippaScanner SDK.
  • Model can be supplied by using the setup method KlippaScanner.setup.set(modelName: "model", modelLabelsName: "labels", modelBundleLocation: ViewController.self)
  • A timer has been added, to automatically capture recognized objects after a certain time has elapsed: KlippaScanner.setup.set(isTimerEnabled: true) and KlippaScanner.setup.set(timerDuration: 0.5)
  • A success message with checkmark icon can be shown instead of a preview of the captured image using KlippaScanner.setup.set(successMessage: "Success!", successPreviewDuration: 0.3)
  • When capturing using a model, padding can be added to the cropped area using KlippaScanner.setup.set(cropPadding: CGSize(width: 200, height: 200)) (this example adds 100px cropping to the left, right, top and bottom of the image).

0.2.0

Changed

  • Build using XCode 12/Swift 5.3

0.1.3

Changed

  • The ImageScannerResult object returned in didFinishScanningWithResult now also contains the cropEnabled variable, indicating the status of the crop button.

0.1.1

Changed

  • A back button has been added in the bottom left corner. It’s visible as long as no photo’s have been taken yet. Pressing the back button dismisses the view controller and calls imageScannerControllerDidCancel on the delegate.

0.1.0

Changed

  • The build system has now been changes to the modern build system, and we now build the library with the option BUILD_LIBRARY_FOR_DISTRIBUTION. We also use XCFrameworks now to package the framework. The Carthage package still links to the traditional fat framework because Carthage does not support XCFramework yet, but the framework is now based on the files from the XCFramework package.

0.0.13

Changed

  • The isMultipleDocumentsModeEnabled option has been added to make a distinction between the multiple documents mode being available at all, and the user toggling the button. allowMultipleDocumentsMode now displays / hides the button whilst isMultipleDocumentsModeEnabled toggles the initial state when the button is visible.

0.0.12

Fixed

  • Fix image preview when cropping pictures that have been taken in landscape.

0.0.11

Changed

  • The primaryColor is now used for the toolbar.
  • The accentColor is used for controls.
  • The overlayColor is used for both the area that will be cropped and the cropping controls.
  • The isAutoScanEnabled and isAutoScanEnabled options have been removed.
  • Reduced the duration of capture animations.
  • The colors for the crop, multiple documents mode and flash toggles have been changed to partially white (disabled state) and fully white (enabled state).

Fixed

  • Pressing the crop-button no longer takes a photo.
  • Fixed inconsistent behavior of isCropEnabled option.
  • Changes to the cropped area were not saved when returning to the camera.
  • The orientation of landscape photos changed to black-white was incorrect.
  • The initial state for allowMultipleDocumentsMode was being ignored.
  • Rotating the photo now also rotates the original picture and not just the cropped area. The cropped area will also be properly rotated.

0.0.10

Added

  • Added default constructor for ImageScannerController.

Changed

  • ImageScannerControllerDelegate now finishes scanning with one object (ImageScannerResult), containing the captured images and the multipleDocumentsModeEnabled property.
  • Added classname to the @objc decorator, to enable Nativescript to discover the correct classes on run time.

0.0.9

Added

  • Added default constructor for ImageScannerController.

Fixed

  • Corrected some typo’s (imageTooDarkMessage, imageTooBrightMessage).

0.0.8
