Grades a Data Matrix barcode using the Print Quality metrics included in the ISO 16022 specification. You must first prepare this Data Matrix barcode image for grading using the Read Data Matrix Barcode node.

Inputs/Outputs
Compatibility

image in

Reference to the image that contains the Data Matrix code you want to grade.

You must first prepare this image for grading using the Read Data Matrix Barcode node.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error

If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

image out

Reference to the image that contains the Data Matrix code.

AIM grading report

Cluster of information detailing the grading information for the Data Matrix code.

If a Data Matrix code can not be located by the Read Data Matrix Barcode node, the node assigns the Data Matrix code an F for all grades.

Overall Grade

Overall letter grade, which is equal to the lowest of the other five letter grades.

Decoding Grade

Letter grade assigned to a Data Matrix code based on the success of the node in decoding the Data Matrix code.

The node sets this grade to A if the node could decode the Data Matrix code, otherwise the node sets this grade to F.

Symbol Contrast Grade

Letter grade assigned to a Data Matrix code based on the symbol contrast raw score.

Print Growth Grade

Print growth letter grade for the Data Matrix code.

Axial Nonuniformity Grade

Axial nonuniformity grade for the Data Matrix code.

Unused Error Correction Grade

Unused error correction letter grade for the Data Matrix code.

AIM score report

Cluster of information detailing the raw AIM scores for the Data Matrix code.

If a Data Matrix code could not be located by the Read Data Matrix Barcode node, the node assigns a zero for all raw scores.

Symbol Contrast

Symbol contrast raw score representing the percentage difference between the mean of the reflectance of the darkest 10 percent and lightest 10 percent of the Data Matrix code.

Print Growth

Print growth raw score for the Data Matrix code, which is based on the extent to which dark or light markings appropriately fill their cell boundaries.

Axial Nonuniformity

Axial nonuniformity raw score for the Data Matrix code, which is based on how much the sampling point spacing differs from one axis to another.

Unused Error Correction

Unused error correction raw score for the Data Matrix code, which is based on the extent to which regional or spot damage in the Data Matrix code has eroded the reading safety margin provided by the error correction.

error out

Error information.

The node produces this output according to standard error behavior.
