Parameter Configuration Classes

PublicRuntimeSettings

You can update most of the parameter settings through the PublicRuntimeSettings class.

class com.dynamsoft.dbr.PublicRuntimeSettings;

Attribute	Type	Descriptions
`terminatePhase`	int	Sets the phase to stop the barcode reading algorithm.
`timeout`	int	Set the maximum time spent on scanning one image (page).
`maxAlgorithmThreadCount`	int	Sets the number of threads the image processing algorithm will use to decode barcodes.
`expectedBarcodesCount`	int	Sets the number of barcodes expected to be detected for each image.
`barcodeFormatIds`	int	BarcodeFormat group 1. Read more in `EnumBarcodeFormat`
`barcodeFormatIds_2`	int	BarcodeFormat group 2. Read more in `EnumBarcodeFormat_2`
`pdfRasterDPI`	int	Sets the output image resolution.
`scaleDownThreshold`	int	Sets the threshold for the image shrinking.
`binarizationModes`	int[]	Sets the mode and priority for binarization.
`localizationModes`	int[]	Sets the mode and priority for localization algorithms.
`furtherModes`	`FurtherModes`	Further modes settings. Please read more in `FurtherModes` class.
`deblurLevel`	int	Sets the degree of blurriness of the barcode.
`intermediateResultTypes`	int	Sets which types of intermediate result to be kept for further reference.
`intermediateResultSavingMode`	int	Sets the mode for saving intermediate result.
`resultCoordinateType`	int	Specifies the format for the coordinates returned.
`textResultOrderModes`	int[]	Sets the mode and priority for the order of the text results returned.
`returnBarcodeZoneClarity`	int	Sets whether or not to return the clarity of the barcode zone.
`region`	`RegionDefinition`	Sets the scan region. Please read more in `RegionDefinition` Class
`minBarcodeTextLength`	int	Sets the range of barcode text length for barcodes search.
`minResultConfidence`	int	The minimum confidence of the result.
`scaleUpModes`	int[]	Sets the mode and priority to control the sampling methods of scale-up for linear barcode with small module sizes.
`pdfReadingMode`	int	Sets the way to detect barcodes from a PDF file when using the DecodeFile method.
`deblurModes`	int[]	Sets the mode and priority for deblurring.
`barcodeZoneMinDistanceToImageBorders`	int	Sets the minimum distance (in pixels) between the barcode zone and image borders.

Code Snippet

PublicRuntimeSettings runtimeSettings = barcodeReader.getRuntimeSettings();
// Make some settings here
// runtimeSettings.****** = ******
barcodeReader.updateRuntimeSettings(runtimeSettings);

FurtherModes

FurtherModes is an extension of the PublicRuntimeSettings class. Through the FurtherModes, you can make advanced settings to process the image for barcode reading.

class com.dynamsoft.dbr.FurtherModes;

Attribute	Type	Descriptions
`colourClusteringModes`	int[]	Sets the mode and priority for colour categorization.
`colourConversionModes`	int[]	Sets the mode and priority for converting a colour image to a grayscale image.
`grayscaleTransformationModes`	int[]	Sets the mode and priority for the grayscale image conversion.
`regionPredetectionModes`	int[]	Sets the region pre-detection mode for barcodes search.
`imagePreprocessingModes`	int[]	Sets the mode and priority for image preprocessing algorithms.
`textureDetectionModes`	int[]	Sets the mode and priority for texture detection.
`textFilterModes`	int[]	Sets the mode and priority for text filter.
`textAssistedCorrectionMode`	int	Sets the mode of text assisted correction for barcode decoding.
`dpmCodeReadingModes`	int[]	Sets the mode and priority for DPM code reading.
`deformationResistingModes`	int[]	Sets the mode and priority for deformation resisting.
`barcodeComplementModes`	int[]	Sets the mode and priority to complement the missing parts in the barcode.
`barcodeColourModes`	int[]	Sets the mode and priority for the barcode colour mode used to process the barcode zone.
`accompanyingTextRecognitionModes`	int[]	Sets the mode and priority to recognize accompanying text.

class com.dynamsoft.dbr.RegionDefinition;

Attribute	Type	Descriptions
`regionTop`	int	The top-most coordinate or percentage of the region.
`regionLeft`	int	The Left-most coordinate or percentage of the region.
`regionRight`	int	The Right-most coordinate or percentage of the region.
`regionBottom`	int	The Bottom-most coordinate or percentage of the region.
