Assembly: | AVL.NET.dll |
Syntax
public static void ReadMultipleBarcodes ( AvlNet.Image inImage, float inMinGradientLength, int inBaseBarWidth, int inDetectionScanCount, int inReadingScanCount, int inScanWidth, float inMinStrength, float inSmoothingStdDev, AvlNet.Polarity inPolarity, IList<AvlNet.Rectangle2D> outBarcodePositions, IList<string> outDecodedTexts )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inMinGradientLength | float | <0.0f, INF> | 8.0f | Minimal gradient length of edge pixels used for detecting barcodes. Default value: 8.0f. | |
inBaseBarWidth | int | <1, INF> | 3 | Estimated width of the thinnest bar. Default value: 3. | |
inDetectionScanCount | int | <1, INF> | 5 | Number of scan lines used in detecting barcode. Default value: 5. | |
inReadingScanCount | int | <1, INF> | 5 | Number of parallel scans run until first successful read. Default value: 5. | |
inScanWidth | int | <1, INF> | 5 | Width of the single scan. Default value: 5. | |
inMinStrength | float | <0.0f, INF> | 5.0f | Minimal strength of an extracted edge. Default value: 5.0f. | |
inSmoothingStdDev | float | <0.0f, INF> | 0.25f | Standard deviation of the gaussian smoothing applied to the profile extracted in each scan. Default value: 0.25f. | |
inPolarity | AvlNet.Polarity | Dark | Specifies whether code is darker or brighter than the background. Default value: Dark. | ||
outBarcodePositions | System.Collections.Generic.IList<AvlNet.Rectangle2D> | Positions of the found barcodes. | |||
outDecodedTexts | System.Collections.Generic.IList<string> | Decoded barcode content. |
