Methods

ApplyImageFilterAsync(PlatformImage, ParametricFilter, ResultOptions)

Applies the filters to an ImageSource asynchronously.

[Obsolete("This method may be moved to ImageProcessor or a related extension class in the future")]
Task<PlatformImage> ApplyImageFilterAsync(PlatformImage image, ParametricFilter filter, ResultOptions resultOptions = null)

Parameters

image PlatformImage

Image.

filter ParametricFilter

Filters.

resultOptions ResultOptions

Result options that specify the result image's storage details.

Returns

Task<PlatformImage>

The image with the applied filters.

CleanUp()

Removes all internally generated files from methods of this interface, as well as all page image files.

Task CleanUp()

Returns

Task

CreatePdfAsync(IEnumerable<FileImageSource>, PDFConfiguration)

Creates a PDF file out of one or more FileImageSource objects. All images must be instances of FileImageSource. Those are images created with ImageSource.FromStream and images stored as files by the SDK (which is the default behavior, corresponds to ResultStorage.File). The generated file will be deleted when calling CleanUp. If you want to keep the file, move it to a folder that you have control over.

Task<Uri> CreatePdfAsync(IEnumerable<FileImageSource> files, PDFConfiguration configuration)

Parameters

files IEnumerable<FileImageSource>

A collection of FileImageSource instances.

configuration PDFConfiguration

Contains the PDF configurations and PDF metadata.

Returns

Task<Uri>

The path to the created file.

CreateSandwichPdfAsync(IEnumerable<FileImageSource>, PDFConfiguration, OcrConfig)

Performs OCR and Creates a PDF file out of one or more FileImageSource objects. All images must be instances of FileImageSource. Those are images created with ImageSource.FromStream and images stored as files by the SDK (which is the default behavior, corresponds to ResultStorage.File). The generated file will be deleted when calling CleanUp. If you want to keep the file, move it to a folder that you have control over.

Task<Uri> CreateSandwichPdfAsync(IEnumerable<FileImageSource> sources, PDFConfiguration pdfConfig, OcrConfig ocrConfig)

Parameters

sources IEnumerable<FileImageSource>

Images containing text.

pdfConfig PDFConfiguration

Contains the PDF configurations and PDF metadata.

ocrConfig OcrConfig

The OCR configuration. If the value is not set, The default value used will be [OCRMode.ScanbotOCR] which is the new ML based configuration. The langauges string is mandatory only if we use the old [Tessarat] based engine.

Returns

Task<Uri>

The result of OCR, containing the recognized text and text structure information.

CreateScannedPageAsync(PlatformImage)

Creates a ScannedPage object from an ImageSource. Used when you need to pass an ImageSource to CroppingPage

[Obsolete("This makes use of the legacy page storage feature. Prefer to use the new ScannedDocument and ScannedPage classes and related APIs.")]
Task<IScannedPage> CreateScannedPageAsync(PlatformImage source)

Parameters

source PlatformImage

Image to use as original

Returns

Task<IScannedPage>

The scanned page.

DetectDocumentQualityAsync(PlatformImage, DocumentQualityAnalyzerConfiguration)

Detects the quality of the document image.

Task<DocumentQuality> DetectDocumentQualityAsync(PlatformImage image, DocumentQualityAnalyzerConfiguration configuration = null)

Parameters

image PlatformImage

configuration DocumentQualityAnalyzerConfiguration

Configure the properties for analyzing quality of the image. Optional.

Returns

Task<DocumentQuality>

GetAllPagesAsync()

Returns all scanned pages currently in persistent storage.

[Obsolete("This makes use of the legacy page storage feature. Prefer to use the new ScannedDocument and ScannedPage classes and related APIs.")]
Task<IReadOnlyCollection<IScannedPage>> GetAllPagesAsync()

Returns

Task<IReadOnlyCollection<IScannedPage>>

ParseBarcodeDocument(string)

Parses the string into one of the supported document type or returns null if none of the supported document types was detected

Task<GenericDocument> ParseBarcodeDocument(string barcodeText)

Parameters

barcodeText string

Returns

Task<GenericDocument>

PerformOcrAsync(IEnumerable<FileImageSource>, OcrConfig)

Performs OCR on an image.

Task<OcrResult> PerformOcrAsync(IEnumerable<FileImageSource> sources, OcrConfig configuration = null)

Parameters

sources IEnumerable<FileImageSource>

Images containing text.

configuration OcrConfig

The OCR configuration. If the value is not set, The default value used will be [OCRMode.ScanbotOCR] which is the new ML based configuration. The langauges string is mandatory only if we use the old [Tessarat] based engine.

Returns

Task<OcrResult>

The result of OCR, containing the recognized text and text structure information.

ReconstructPage(string, PointF[], ParametricFilter[], DocumentDetectionStatus)

Reconstructs the Page object from the pageId and other parameters, received previously in the document detection result.

[Obsolete("This makes use of the legacy page storage feature. Prefer to use the new ScannedDocument and ScannedPage classes and related APIs.")]
