grayscale_transformation_modes
Specifies how grayscale transformations should be applied, including whether to process inverted grayscale images and the specific transformation mode to use.
It is a list of 8 integers, where each integer represents a mode specified by the EnumGrayscaleTransformationMode enumeration.
View the parameter reference page of GrayscaleTransformationModes for more detail about grayscale transformation modes.
grayscale_enhancement_modes
Specifies how to enhance the quality of the grayscale image.
It is a list of 8 integers, where each integer represents a mode specified by the EnumGrayscaleEnhancementMode enumeration.
View the parameter reference page of GrayscaleEnhancementModes for more detail about grayscale enhancement modes.
colour_mode
Specifies the colour mode of the output image.
It is a value of the EnumImageColourMode enumeration.
View the parameter reference page of ColourMode for more detail about colour mode.
Default value
0, which means output image in colour mode.
page_size
Specifies the page size (width by height in pixels) of the normalized image.
brightness
Specifies the brightness of the normalized image.
Value Range
[-100,100]
Default value
0
contrast
Specifies the contrast of the normalized image.
Value Range
[-100,100]
Default value
0
max_threads_in_one_task
Specifies the maximum available threads count in one document normalization task.
Value Range
[1, 256]
Default value
4
scale_down_threshold
Specifies the threshold for the image shrinking.
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.
min_quadrilateral_area_ratio
Specifies the minimum ratio between the target quadrilateral area and the total image area. Only those exceeding this value will be output (measured in percentages).
Value Range
[0, 100]
Default Value
0, which means no limitation.
expected_documents_count
Specifies the number of documents expected to be detected.
Value Range
[0, 0x7fffffff]
Default Value
0, which means the count is unknown. The library will try to find at least 1 document.
