QRCodeReport
Describes the QR code that the function read.
Elements
| Name | Type | Description |
|---|---|---|
| found | unsigned int | This element is TRUE if the function located and decoded a QR code and FALSE if the function failed to locate and decode a QR code. |
| data | unsigned char* | The data encoded in the QR code. |
| dataLength | unsigned int | The length of the data array. |
| boundingBox[4] | PointFloat | An array of four points describing the rectangle surrounding the QR code. |
| tokenizedData | QRCodeDataToken* | Contains the data tokenized in exactly the way it was encoded in the code. This is useful if the code is encoded using multiple languages. |
| sizeOfTokenizedData | unsigned int | Size of the tokenized data. |
| numErrorsCorrected | unsigned int | The number of errors the function corrected when decoding the QR code. |
| dimensions | unsigned int | The number of rows and columns that are populated for the QR code, measured in cells. |
| version | unsigned int | The version of the QR code. The version indicates how much information can be encoded and how much redundancy is included inside the code. |
| modelType | QRModelType | This option allows you to specify what type of QR code this is. Micro QR codes have only one target in the top left. Model 1 codes have alignment "dashes" along the bottom and right side of the symbol. |
| streamMode | QRStreamMode | The format of the data encoded in the stream. |
| matrixPolarity | QRPolarities | The polarity of the QR code. |
| mirrored | unsigned int | This element is TRUE if the QR code appears mirrored in the image and FALSE if the QR code appears normally in the image. |
| positionInAppendStream | unsigned int | Indicates what position the QR code is in with respect to the stream of data in all codes. It is possible for a QR code to be part of a larger array of codes. |
| sizeOfAppendStream | unsigned int | Specifies how many QR codes are part of a larger array of codes. Sometimes a QR code is part of a larger array of codes. |
| firstEAN128ApplicationID | int | The first EAN-128 Application ID encountered in the stream. This is only useful for EAN-128 codes and for mixed/appended EAN-128 codes, refer to the tokenized output. |
| firstECIDesignator | int | The first Regional Language Designator encountered in the stream. This is only useful for ECI codes. For multiple language ECI codes, refer to the tokenized output. |
| appendStreamIdentifier | unsigned int | Specifies what stream the QR code is in relation to when the code is part of a larger array of codes. |
| minimumEdgeStrength | unsigned int | The strength of the weakest edge the function used to find the coarse location of the QR code in the image. Use this value as a guide for setting the edgeThreshold element of the searchOptions parameter of imaqReadQRCode(). |
| demodulationMode | QRDemodulationMode | The demodulation mode the function used to locate the QR code. If demodulationMode is set to IMAQ_AUTO_DETECT_DEMODULATION_MODE in the searchOptions parameter of imaqReadQRCode(), this element indicates the recommended demodulation mode for this image. |
| cellSampleSize | QRCellSampleSize | The cell sample size the function used to locate the QR code. If cellSampleSize is set to IMAQ_AUTO_DETECT_CELL_SAMPLE_SIZE in the searchOptions parameter of imaqReadQRCode(), this element indicates the recommended cell sample size for this image. |
| cellFilterMode | QRCellFilterMode | The cell filter mode the function used to locate the QR code. If cellFilterMode was set to IMAQ_AUTO_DETECT_CELL_FILTER_MODE in the searchOptions parameter of imaqReadQRCode(), this element indicates the recommended cell filter mode for this image. |
