Detailed Description

This structure returns information about a decoded barcode.

When the function CvcBcDecodeBarcode is called, a pointer to this type of structure is passed. After the call this structure contains information about the recognised barcode.

If a barcode cannot be read, it is possible to obtain more detailed information about the barcode evaluation via the elements decoding_result and error_reason. Only those elements of the info-structure will be filled for which informations were available at the moment the evaluation stopped.

Attention: This structure is used for different kind of barcodes. Thus, only some of these parameters are used for different kind of barcodes.

General information:: type, char_read, char_truncated, num_digits, decoding_time, ecc_level, format, num_rows, num_columns, p1_x, p1_y, p2_x, p2_y, p3_x, p3_y, p4_x, p4_y, used_ecc, fnc1, fnc2, fnc3, fnc4, full_ascii, number_system, bar1, bar2, bar3, bar4, bar5, bar6, bar7, bar8, contrast1, contrast2, contrast3, contrast4, contrast5, contrast6, contrast7, contrast8, code_position_x1,
code_position_y1, code_position_x2, code_position_y2,

code_position_x3, code_position_y3, code_position_x4, decoding_result, and error_reason.

SonyCode:: These are the info-structure parameters regarding the SonyCode. Some elements of the info-structure are not used for decoding the SonyCode and therefore there will not be set.

num_digits, p1_x, p1_y, p2_x, p2_y, resolution, contrast, fnc1, and fnc2.

Code Grading (2D):: If the function "code grading" is active the following information will be determined:

grade_reference_decode, grade_symbol_contrast, grade_axial_nonuniformity, grade_unused_error_correction, grade_grid_nonuniformity, scan_grade, symbol_contrast, axial_nonuniformity, grid_nonuniformity, unused_error_correction, print_growth, and angle_of_distortion.

QR code:: After decoding of a QR Code the info structure contains meta information regarding the result:

type, char_read, ecc_level, format, num_rows, num_columns, p1_x, p1_y, p2_x, p2_y, p3_x, p3_y, p4_x, p4_y, resolution, used_ecc, contrast, number_system, decoding_time, decoding_result, and error_reason.

Code Grading (QR):: QR code grading will produce the following results (if selected in the CvcBcSetQRCodeGrading call):

grade_reference_decode, scan_grade, grade_symbol_contrast, grade_axial_nonuniformity, grade_grid_nonuniformity, grade_unused_error_correction, angle_of_distortion, grade_modulation, grade_fixed_pattern_damage, grade_format_information, grade_version_information, r_min, r_max, global_threshold

The p2_x element describes the x-coordinate of the second edge point of the detected code.

Attention: For the codes Data Matrix, PDF 417 and Pharmacode all four points are set. For normal 1D Barcodes only two points are set.

In case of a SonyCode the properties p1_x, p1_y, p2_x, and p2_y define the image coordinates marking the position where the SonyCode has been read. p1 is located at the begin of the start sign (A) and p2 is always be located at the end of the stop sign (F).

In case of a QR code the edge-points of the code are counterclockwise. If the code is not decoded the markers could be outside the code. If only one marker of the QR code is found, the coordinates are stored here.

short print_growth

This property contains the print growth multiplied with a factor of 100.

If the print growth is inactive print_growth will be 0.

Attention: This property is only used with Code Grading.

CVC_BC_QUALITY_INFO quality_info

1D Code Grading Results.

short r_max

Maximum contrast found during grading.

Attention: This property is only used with QR Code Grading.

short r_min

Minimum contrast found during grading.

Attention: This property is only used with QR Code Grading.

short resolution

The resolution specifies the smallest width unit in the code in multiples of a 10th of a pixel.

In case of a SonyCode this may either be the narrowest width of a line and/or of a gap.

short scan_grade

This property contains the "scan grade" which is the lowest of the parameter grades achieved above.

Only active grades will not incur in the result of the scan grade.

Attention: This property is only used with Code Grading.
