Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inRoiFilNet.Rectangle2D?Region of interest. Default value: ftl::NIL.
inRoiAlignmentFilNet.CoordinateSystem2D?Coordinate system for the region of interest. Default value: ftl::NIL.
inCodeParamsFilNet.DataMatrixCodeParamsSpecification of codes that can be detected.
inDetectionParamsFilNet.DataMatrixDetectionParamsSpecification of the way the codes are being detected.
inMaxCodeCountint<0, INF>2Maximum number of codes to be found. Default value: 2.
inAllowMultipleScalesboolFalseSpecifies whether codes of different module sizes are expected. Default value: False.
outDataMatrixCodesSystem.Collections.Generic.IList<FilNet.DataCode>
