AVS.ReadMultipleDataMatrixCodes Method
Detects and recognizes several Data Matrix codes in one image.
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
public static void ReadMultipleDataMatrixCodes ( AvlNet.ReadDataMatrixCodes_State ioState, AvlNet.Image inImage, AvlNet.Rectangle2D? inRoi, AvlNet.CoordinateSystem2D? inRoiAlignment, AvlNet.DataMatrixCodeParams inCodeParams, AvlNet.DataMatrixDetectionParams inDetectionParams, int inMaxCodeCount, bool inAllowMultipleScales, IList<AvlNet.DataCode> outDataMatrixCodes, IList<AvlNet.Path> outCandidates, NullableValue<AvlNet.Rectangle2D> outAlignedRoi )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
ioState | AvlNet.ReadDataMatrixCodes_State | ||||
inImage | AvlNet.Image | Input image. | |||
inRoi | AvlNet.Rectangle2D? | Region of interest. Default value: atl::NIL. | |||
inRoiAlignment | AvlNet.CoordinateSystem2D? | Coordinate system for the region of interest. Default value: atl::NIL. | |||
inCodeParams | AvlNet.DataMatrixCodeParams | Specification of codes that can be detected. | |||
inDetectionParams | AvlNet.DataMatrixDetectionParams | Parameters of the code detection algorithm. | |||
inMaxCodeCount | int | <0, INF> | 2 | Maximum number of codes in one image. Default value: 2. | |
inAllowMultipleScales | bool | False | Specifies whether to continue search for codes at a higher resolution even when some codes have already been found at a lower resolution. Default value: False. | ||
outDataMatrixCodes | System.Collections.Generic.IList<AvlNet.DataCode> | List of codes that have been correctly detected and decoded. | |||
outCandidates | System.Collections.Generic.IList<AvlNet.Path> | Diagnostic information about detection results. | |||
outAlignedRoi | AvlNet.NullableValue<AvlNet.Rectangle2D> | Input ROI after transformation (in the image coordinates). Can be null to skip this parameter calculation. |
