Constructor Detail

DocImageProc

public DocImageProc()

Deprecated.

Constructor. load(android.app.Application)() must be called before

DocImageProc

public DocImageProc(android.app.Application app)

Deprecated.

Constructor

Parameters:

app - Application instance to initialize library

Method Detail

load

public static boolean load(android.app.Application app)

Deprecated.

Optionally initialize library by @param app Application instance. That will possible to call DocImageProc() without Application argument

Parameters:

app - Android Application

Returns:

true if library was loaded successfully.

validate

public boolean validate()

Deprecated.

Validate object initialization

Returns:

Initialization successful

close

public void close()

Deprecated.

Finish working with SDK instance

supportImageSize

public android.graphics.Point supportImageSize(@NonNull
                                               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. Special case: for input (-1, -1) returns maximal image dimensions

correctDocument

public Metaimage correctDocument(@NonNull
                                 Metaimage sourceBitmap,
                                 @NonNull
                                 Corners corners)

Deprecated.

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.

detectDocumentCorners

public boolean detectDocumentCorners(@NonNull
                                     Metaimage sourceBitmap,
                                     boolean needPreview,

                                     PxDocCorners docCorners)

Deprecated.

detects on GPU document corners in the page image, saves document detection quality into the page.

Parameters:

sourceBitmap - input image

needPreview - generate preview image

docCorners - detection parameters and document corners as output

Returns:

true if success, otherwise false.

validateDocumentCorners
