class SimplifiedDocumentNormalizerSettings

Methods & Attributes

Attributes	Type	Description
`grayscaleTransformationModes`	EnumGrayscaleTransformationMode[]	An array of GrayscaleTransformationMode. It controls whether to detect the inverted document boundary.
`grayscaleEnhancementModes`	EnumGrayscaleEnhancementModes[]	An array of GrayscaleEnhancementModes.
`colourMode`	EnumImageColourMode	The grayscale transformation mode. It controls whether to decode the inverted text.
`pageSize`	int[]	The page size.
`brightness`	int	The brightness.
`contrast`	int	The contrast.
`maxThreadsInOneTask`	int	The maximum number of threads in one task.
`scaleDownThreshold`	int	The scale down threshold.

Methods	Description
`toJson`	Generate a JSON string from this `SimplifiedDocumentNormalizerSettings` object.
`fromJson`	Create a `SimplifiedDocumentNormalizerSettings` object from a JSON string.

grayscaleTransformationModes

Defines the grayscale transformation modes with an array of EnumGrayscaleTransformationMode items. This parameter is important when working with inverted documents, and must be used in order to locate the inverted document boundary.

EnumGrayscaleTransformationMode[] grayscaleTransformationModes;

grayscaleEnhancementModes

Defines the grayscale enhancement modes with an array of EnumGrayscaleEnhancementModes items. This parameter can be quite powerful in increasing the border detection rate of your application should you experience any trouble in that area. To learn more about the grayscaleEnhancementModes and how they can be used, please visit the main GrayscaleEnhancementModes parameter page.

EnumGrayscaleEnhancementMode[] grayscaleEnhancementModes;

colourMode

Defines the colour mode of the normalized image with an EnumImageColourMode member. By default, the normalized image will output in colour. In order to make the result image grayscale or binary, setting the colourMode to the corresponding pixel type will do the trick.

EnumImageColourMode colourMode;

pageSize

Defines the page size of the normalized image through an integer array.

int[] pageSize;

brightness

Defines the brightness of the normalized image result with an integer.

int brightness;

contrast

Defines the contrast of the normalized image result with an integer.

int contrast;

maxThreadsInOneTask

Defines the maximum number of threads dedicated to a single task.

int maxThreadsInOneTask;

scaleDownThreshold

If the original image size is quite large, then the scaledownThreshold can be used to shrink the image and speed up the processing. If the shorter edge size is larger than the defined scale down threshold, the library will calculate the required width and height of the image and shrink it to that size before moving forward in the process.

int scaleDownThreshold;

toJson

Generate a JSON string from this SimplifiedDocumentNormalizerSettings object.

String toJson()

Return Value

A JSON string that contains all the information of this object.

fromJson

Create a SimplifiedDocumentNormalizerSettings object from a JSON string.

static SimplifiedDocumentNormalizerSettings fromJson(String json);

Parameters

json: A JSON string that contains all SimplifiedDocumentNormalizerSettings required information.

Return Value

A SimplifiedDocumentNormalizerSettings object.
