barcode_format_ids
Specifies the targeting format(s) of the barcode(s) to be decoded.
It is a bitwise OR combination of one or more values from the EnumBarcodeFormat enumeration.
expected_barcodes_count
Specifies the expected barcode count. The default value is 0.
Remarks
- Set
expected_barcodes_countto 0 if the barcode count is unknown. The library will try to find at least 1 barcode. - Set
expected_barcodes_countto 1 to reach the highest speed for processing single barcode. - Set
expected_barcodes_countto “n” if there will be “n” barcodes to process from an image. - Set
expected_barcodes_countto the highest expected value if there exists multiple barcode but the exact count is not confirmed.
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.
localization_modes
Specifies how to localize barcodes.
It is a list of 8 integers, where each integer represents a mode specified by the EnumLocalizationMode enumeration.
View the parameter reference page of LocalizationModes for more detail about location modes.
deblur_modes
Specifies the mode and priority for deblurring.
It is a list of 10 integers, where each integer represents a mode specified by the EnumDeblurMode enumeration.
View the parameter reference page of DeblurModes for more detail about deblur modes.
min_result_confidence
Specifies the minimum result confidence to filter out the low confidence results. The default value is 30.
min_barcode_text_length
Specifies the minimum barcode text length to filter out the unqualified results.
barcode_text_regex_pattern
Specifies the RegEx pattern of the barcode text to filter out the unqualified results.
max_threads_in_one_task
Specifies the maximum available threads count in one barcode decoding task.
Value Range
[1, 256]
Default value
4
scale_down_threshold
Specifies the threshold for 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 target image and shrink the image to that size before further operation. Otherwise, the library will perform operation on the original image.
