QRCellFilterMode
Specifies the mode used to determine the pixel value for each cell.
Elements
| Name | Value | Description |
|---|---|---|
| IMAQ_QR_CELL_FILTER_MODE_AUTO_DETECT | -2 | The function will try all filter modes and uses the one that decodes the QR code within the fewest iterations and utilizing the least amount of error correction. |
| IMAQ_QR_CELL_FILTER_MODE_AVERAGE | 0 | The function sets the pixel value for the cell to the average of the sampled pixels. |
| IMAQ_QR_CELL_FILTER_MODE_MEDIAN | 1 | The function sets the pixel value for the cell to the median of the sampled pixels. |
| IMAQ_QR_CELL_FILTER_MODE_CENTRAL_AVERAGE | 2 | The function sets the pixel value for the cell to the average of the pixels in the center of the cell sample. |
| IMAQ_QR_CELL_FILTER_MODE_HIGH_AVERAGE | 3 | The function sets the pixel value for the cell to the average value of the half of the sampled pixels with the highest pixel values. |
| IMAQ_QR_CELL_FILTER_MODE_LOW_AVERAGE | 4 | The function sets the pixel value for the cell to the average value of the half of the sampled pixels with the lowest pixel values. |
| IMAQ_QR_CELL_FILTER_MODE_VERY_HIGH_AVERAGE | 5 | The function sets the pixel value for the cell to the average value of the ninth of the sampled pixels with the highest pixel values. |
| IMAQ_QR_CELL_FILTER_MODE_VERY_LOW_AVERAGE | 6 | The function sets the pixel value for the cell to the average value of the ninth of the sampled pixels with the lowest pixel values. |
| IMAQ_QR_CELL_FILTER_MODE_ALL | 8 | The function tries each filter mode, starting with IMAQ_QR_CELL_FILTER_MODE_AVERAGE and ending with IMAQ_QR_CELL_FILTER_MODE_VERY_LOW_AVERAGE, stopping once a filter mode decodes correctly. |
| IMAQ_QR_CELL_FILTER_MODE_SIZE_GUARD | 0xFFFFFFFF | Reserved |
