SimplifiedDocumentNormalizerSettings

The SimplifiedDocumentNormalizerSettings class contains settings for document normalization. It is a sub-parameter of SimplifiedCaptureVisionSettings

typedef class SimplifiedDocumentNormalizerSettings

Attributes Summary

grayscaleTransformationModes

Set the grayscale transformation modes with an array of enumeration GrayscaleTransformationMode. View the reference page of GrayscaleTransformationMode for more detail about grayscale transformation modes.

GrayscaleTransformationMode grayscaleTransformationModes[];

grayscaleEnhancementModes

Set the grayscale enhancement modes with an array of enumeration GrayscaleEnhancementMode. View the reference page of GrayscaleEnhancementMode for more detail about grayscale enhancement modes.

GrayscaleEnhancementMode grayscaleEnhancementModes[];

colourMode

Set the output image colour mode.

ImageColourMode colourMode;

Value Range

“ICM_BINARY”, “ICM_GRAYSCALE”, “ICM_COLOUR”

Default value

“ICM_COLOUR”

pageSize

Set the page size (width by height in pixels) of the normalized image.

int pageSize[];

brightness

Set the brightness of the normalized image.

int brightness;

Value Range

[-100,100]

Default value

0

contrast

Set the contrast of the normalized image.

int contrast   

Value Range

[-100,100]

Default value

0

maxThreadsInOneTask

Set the maximum available threads count in one document normalization task.

int maxThreadsInOneTask;

Value Range

[1, 256]

Default value

4

scaleDownThreshold

Sets the threshold for the image shrinking.

int scaleDownThreshold;

Value Range

[512, 0x7fffffff]

Default Value

2300

Remarks

If the shorter edge size is larger than the given threshold value, the library will calculate the required height and width of the barcode image and shrink the image to that size before detection. Otherwise, the library will perform document detection on the original image.
