Class ImageProcessing

Provides managed wrappers around the native image processing pipeline, exposing document correction and binarization helpers.

Namespace: ImageSdkWrapper Assembly: ImageSdkWrapper.MAUI

Inheritance: object

public class ImageProcessing : IDisposable

Method

CorrectDocument(MetaImage, Corners)

Performs perspective correction using detected document corners.

public MetaImage CorrectDocument(MetaImage sourceBitmap, Corners corners)

Parameters

  • sourceBitmap (MetaImage): Input image.
  • corners (Corners): Detected document corners; when omitted the original image is returned.

Returns

  • MetaImage: Corrected image or null if refinement fails.

DetectDocumentCorners(MetaImage)

Detects document corners for the supplied image.

public Corners DetectDocumentCorners(MetaImage sourceBitmap)

Parameters

  • sourceBitmap (MetaImage): Input image prepared with the native SDK.

Returns

  • Corners: Corner structure when detection succeeds; otherwise null.

Dispose()

Disposes of native resources retained by the processing instance. No-op because the wrapper does not own handles.

public void Dispose()

ImageBWBinarization(MetaImage)

Produces a high-contrast black-and-white rendition of the supplied image.

public MetaImage ImageBWBinarization(MetaImage sourceBitmap)

Parameters

  • sourceBitmap (MetaImage): Input image.

Returns

  • MetaImage: Refined meta image or null if the native call fails.

ImageColorBinarization(MetaImage)

Produces a color-enhanced binarised copy suitable for preserving highlights in colour documents.

public MetaImage ImageColorBinarization(MetaImage sourceBitmap)

Parameters

  • sourceBitmap (MetaImage): Input image.

Returns

  • MetaImage: Refined meta image or null if the native call fails.

ImageGrayBinarization(MetaImage)

Produces a grayscale binarised copy that retains tonal detail while enhancing readability.

public MetaImage ImageGrayBinarization(MetaImage sourceBitmap)

Parameters

  • sourceBitmap (MetaImage): Input image.

Returns

  • MetaImage: Refined meta image or null if the native call fails.

ImageOriginal(MetaImage)

Applies orientation compensation to the provided MetaImage and returns a refined copy.

public MetaImage ImageOriginal(MetaImage sourceBitmap)

Parameters

  • sourceBitmap (MetaImage): Source image; must not be null.

Returns

  • MetaImage: The refined image or null when the native SDK fails to process it.

ImageWithoutRotation(MetaImage)

Returns the original image without applying additional rotation (legacy helper).

[Obsolete("Deprecated")]
public MetaImage ImageWithoutRotation(MetaImage sourceBitmap)

Parameters

  • sourceBitmap (MetaImage)

Returns

  • MetaImage

SupportImageSize(PxlPoint)

Returns the supplied size unchanged. Kept for API compatibility with legacy platforms.

public PxlPoint SupportImageSize(PxlPoint imageSize)

Parameters

  • imageSize (PxlPoint): Input image bounds.

Returns

  • PxlPoint
