Field Detail

recycle

public boolean recycle

Default flag to recycle images after processing Set to false if it isn't desirable behaviour

Method Detail

validate

@Deprecated
public boolean validate()

Deprecated. Validate object initialization

Returns:

Initialization successful. Always true

supportImageSize

@Deprecated
public android.graphics.Point supportImageSize(android.graphics.Point imageSize)

Deprecated. Returns max supported image size. NOTE: Using Point class as size

Parameters:

imageSize - input image size.

Returns:

maximal supported image size. Always imageSize

detectDocumentCorners

public Corners detectDocumentCorners(MetaImage sourceBitmap,
                                     @NonNull
                                     android.os.Bundle params)

detects document corners in the page image.

Detection parameters.

• @deprecated ImageSdkLibrary.SDK_IS_SMART_CROP boolean output. Routine set to true if detection was successfully and otherwise false
• ImageSdkLibrary.SDK_CHECK_DOCUMENT_GEOMETRY boolean input. Perform additional document geometry check
• ImageSdkLibrary.SDK_DOCUMENT_FULLNESS_CHECKED boolean output. Document area checked
• ImageSdkLibrary.SDK_DOCUMENT_DISTORTION_CHECKED boolean output. Document distortion checked

Parameters:

sourceBitmap - input image

params - detection parameters on input and detection as output

Returns:

document corners on success, otherwise null

validateDocumentCorners

@Deprecated
public static boolean validateDocumentCorners(@NonNull
                                                           Corners corners,
                                                           @NonNull
                                                           android.graphics.Point bounds)

Deprecated. Use DocumentCutout instead Validate document corners order compliance to order UL-UR-BL-BR (required by Corners).

Parameters:

corners - document corners to validate

bounds - image size (already rotated!)

Returns:

true if corners is valid

DocumentCutout.validateCorners(com.pixelnetica.imagesdk.Corners, android.graphics.Point)

correctDocument

public MetaImage correctDocument(MetaImage sourceBitmap,
                                 Corners corners)

Corrects document perspective distortions in the image, warping corners to corrected image rectangle.

Parameters:

sourceBitmap - source image containing the document.

corners - 4 corners in the source image coordinate space as Corners class

Returns:

image containing the document without perspective distortions.
