Class that represents a barcode type.

This is the abstract base class for any of the adjustable filters in ScanbotSDK. It provides the basic logic for filtering images using the GPU or the CPU. For GPU-based filtering the SDK uses preferrably Apples Metal API where available and falls back to OpenGLES if Metal is not available. If GPU-based filtering is not supported at all, the slower CPU-based filtering is used.

A basic camera view controller. Can be used for custom video frame detection.

The energy management configuration object for a ‘SBSDKBaseScannerViewController’ and its subclasses. ‘SBSDKBaseScannerViewController’ and subclasses sport a customizable energy management system.

Since detectors and recognizers running on a live video feed can put a lot of load onto the CPU and/or GPU of the device, causing the battery to drain quickly and running the device hot, you can customize the energy consumption using this class by configuring the rate of detections/recognitions per second in performance mode as well as in energy saving mode.

In performance mode the detectors/recognizers will be fed with a higher, configurable rate of video frames per second. After a certain, configurable period of inactivity the energy save mode will be engaged and the rate of detections/recognitions will be reduced to a lower (configurable) rate. You can also configure the time of inactivity before the automatic mode switches from performance to energy save mode.

Inactivity here means that both of the following conditions are met: 1) The device did not register significant motion for this period. 2) No positive detector/recognizer results have been registered during this period.

Once in energy save mode the device can only return to performance mode if it is moved significantly or a positive detection/recognition result was registered.

The general configuration object for a ‘SBSDKBaseScannerViewController’ and its subclasses.

A highly customizable camera view controller that delivers a basic camera functionality along with video frame extraction and preprocessing, orientation correction and still image capturing.

Additionally you can opt-in several features using the SBSDKBaseScannerXXXConfiguration classes, e.g. zooming, energy management and view finder.

This class provides functions to be used and overwritten by subclasses to implement different detectors and recognizers.

The view finder configuration object for a ‘SBSDKBaseScannerViewController’ and its subclasses. Sometimes it is necessary to limit a live video frame detection or recognition to a certain rectangular area with a specific aspect ratio: the region or rectangle of interest. This is where a view finder comes in. It crops the video frame to that region of interest before passing it to any detector or recognizer. Usually the performance of detectors/recognizers gain a benefit from it because less pixels must be processed. Additionally, to guide the user, the view finder visualizes the region of interest by drawing a rectangle around on the user interface.

Since the display resp. the camera view size differs from device to device specifying the region of interest in absolute screen points would require some additional calculations and therefore be inconvenient. Instead a combination of aspect ratio and minimum distances to the view(screen) edges is used.

The zoom configuration object for a ‘SBSDKBaseScannerViewController’ and its subclasses. ‘SBSDKBaseScannerViewController’ and subclasses allow the user to zoom the camera. This class lets you customize the zooming user experience.

A UIViewController subclass to show a camera screen and run a user guiding document detector. The detection result is visualized using a polygonal bezier path. This class cannot be instanced from a storyboard. Instead it is installing itself as a child view controller onto a given parent view controller. This is a simpler version of ‘SBSDKScannerViewController’ that is more in-line with other classic UI SDK components. As a subclass of ‘SBSDKBaseScannerViewController’ it benefits from all its advantages, e.g. zooming, view finder, and energy management.

Helper class to catch NSExceptions from with Swift code.

A UIView subclass to display a view finder with colored background and transparent cutout with the given aspect ratio.

A simple frame limiter class. An object can use this class to limit the number of events fired per second. E.g. A camera device captures video frames with 60 frames per second and passes them to a detector. Use this class to limit the number of detector runs to a smaller value, like 20 frames per second, skipping the remaining 40 frames per second. As the detector needs lots of CPU power this limit can drastically reduce CPU usage and therefore saves battery.

A class to process images asynchronously: the heart of the Scanbot SDK image processing module. As image processing is most often consuming lots of memory this class processes images on a serial queue ensuring a minimum of large images in memory. Each operation reads the image from the imageURL, processes it and, if outputImageURL is a valid file URL, writes the result to outputImageURL. Upon completion completionHandler is called on main thread in a synchronous matter. After your completionHandler finished executing the next operation is enqueued. Its resultInfo dictionary contains the processed image, the source image URL and the destination image URL if specified.

This class summarizes the results of an optical character recognition (OCR) operation for number of pages. It contains the array of SBSDKOCRPages. For convenience this immutable class conforms to NSCopying protocol.

Part of the optical character recognitions result. This result contains multiple SBSDKOCRResultBlock objects. Each block represents a text paragraph, a text line or a word and contains information about it, like the found text, the bounding box, where in the image the paragraph/line/word can be found, the confidence value and the type. For convenience this immutable class conforms to NSCopying protocol.

A factory class to enqueue and execute optical character recognition operations: the heart of the Scanbot SDK OCR module. It performs OCR operations on either a single image or a collection of images, see SBSDKImageStoring. Additionally it can perform a standalone page analysis on a single image. All of the operations are dispatched to a single serial queue to ensure low memory footprint and optimum CPU load.

Any text recognition operation will fail with an error if all of the specified languages are missing as language files. If the specified languages are partially available a warning will be logged, but the operation executes without using the missing languages. Please see the section “Optical Character Recognition” of the main SDK documentation for more details about the OCR language files.

The number of languages passed to OCR operations have a significant impact on the performance: the more languages, the slower the recognition process.

Enables reading and writing of PDF metadata attributes like author, creator, title, keywords etc. to PDF files. Caution: If you want to use this feature your app must import the PDFKit module.

Class used to extract pages from a PDF file and returns them in various ways. The synchronous functions of this class are running in the same thread that they are called from, so it is up to you to control the concurrency. The asynchronous functions run in a shared queue to prevent memory pressure when running multiple extractions at the same time. It is recommended to use background queues in most cases. Currently the flattening of the PDF document is user’s responsibility. So if the document will have unflattened annotations (except signs), they will not be exported.

A class to render an ordered collection of images into a basic, non-searchable PDF. Very fast. It does not perform OCR.

Describes the result of a page layout analyzing operation. It contains page orientation, writing direction and text line order as well as a deskew angle. This result can be used to process the input image before running an OCR operation on it, e.g.

• Rotate the image to let the page orientation flip to SBSDKPageOrientationUp,
• Apply a rotation with the deskewAngle to remove distortion and get perfectly aligned text lines.
• Limit recognition languages to languages that use the analyzer results writingDirection and textlineOrder to achieve much better OCR performance. For convenience this immutable class conforms to NSCopying protocol.

This class represents a 4-gon, a polygon with 4 edges. The polygons points are stored in a normalized unit coordinate system from {0, 0} to {1, 1}.
