Parameters
[in]configHandle to the configuration or NULL to use the default configuration.

[in]symbol_contrastEvaluate / don't evaluate symbol contrast.

The parameter symbol_contrast = TRUE specifies that the symbol contrast will be calculated and considered in the scan grade.

)

Defines the parameters for calculating grades on QR codes.

By default, grading for QR is disabled. Enable it by calling this function and setting the active parameter to true.

When grading QR codes, it should be the aim to have the code plus the code's entire quiet zone (usually 4 module sizes for standard size codes and 2 module sizes for micro QR codes) contained inside the area of interest used for grading. If this is not the case, CVC Barcode will distinguish two situations:

  1. the quiet zone extends beyones the area of interest, but the code is fully visible inside the area of interest.
  2. Parts of the code are outside the area of interest.

In case 1. the fact that part of the quiet zone is outside the area of interest will not reduce the grading result. The code_quiet_zone_out_of_aoi member of the grading result will be set to true to indicate the situation, and only the part of the quiet zone that lies within the area of interest will be taken into account when calculating grading results. Generally speaking, however, it is preferable to have the whole quiet zone inside the are of interest.

In case 2 the code_out_of_aoi member of the result will be set to true. Only the parts of the code that lie within the area of interest will be used for grading, but code words that lie outside the area of interest will usually reduce the unused_error_correction grade.

Parameters
[in]configHandle to the configuration or NULL to use the default configuration.
[in]activeActivates (true) or deactivates (false) code grading. By default, code grading is deactivated.
[in]symbol_contrastActivates (true) or deactivates (false) the calculation of the symbol_contrast grade.
