The dmatrix plugin reads and decodes Data Matrix 2D barcodes. The resulting text becomes the value of the field.

Configuration

1.Tick check-box to Include text when exporting if required (default is unchecked).
2.You may opt to run in Debug mode by ticking the check-box (default is unchecked).
3.If the barcode is unrecognizable, specify what 'Action on OCR failure' is to be taken:
oLeave blank or
oProvide dummy data (default).
4.Some bar-code reading devices are "omnidirectional" – they use mirrors to enable them to capture bar-codes presented at different orientations. A mirror command can reflect the matrix columns/rows to restore the original bar-code. Select an appropriate Mirror option from the drop-down list:
oNormal (default)
oMirror
oNormal & mirror
5.The code may be printed so that the edges of adjacent black elements join together, with white elements between, or vice-versa. Select a Colour option from the drop-down list:
oBlack (default)
oWhite
oAny.
6.Select a Speed option from the drop-down list:
oRobust (default)
oFast. Smaller code but at the expense of poorer error-correction.
7.Performance can be optimized for specific applications by selecting a Mode option from the drop-down list:
oStandard (default)
oDotPeen used for permanent (engraved) marking of substrate.
oFax Data Matrix 2D error correction handling makes it the barcode of choice for faxing.
oSt+Dot
8.DataMatrix specification compliance grading may be set up: choose whether to switch Verify on or not:
oYes (default)
oNo
9.Edge-detection algorithms may be applied to sharpen the contrast at element boundaries; a mask emphasizes the pixels at the centers of the elements. Choose a Filter option from the drop-down list:
oNone (default)
oSharp1
oSharp2
oSharp mask
10.Click OK.
