WriterSetting.MinWidth for DataMatrix

Hi,

I am using the BarcodeWriter for DataMatrix barcodes.
Why is the MinWidth minimum value (as also stated in the documentation) 2.
When I am setting this to 1 it seems to be ignored and 2 is used instead.
Are there any technical restrictions that require MinWidth to be greater than or equal to 2?

kind regards,
Roman

Hello Roman,

It's a limitation in our SDK. We do not recommend to use barcodes with cell width 1.

You can generate barcode with a cell width equal to 1 as follows:
  • Generate barcode in vector form (as graphical path)
  • Scale barcode (graphical path)
  • Print scaled barcode
Best regards, Alexander

hi,

thanks for your quick answer!
could you state, why it is not recommended?
are there any common pitfalls in using barcodes with a low cell width?

kind regards

Barcode reading algorithm works as follows:
  • Recognition algorithm reads information about cells of barcode. In most cases recognition algorithm can correctly read information about a cell of barcode if the cell has 2-3 pixels and 1-2 pixels of cell are lost.
  • Error correction algorithm is used to verify/restore barcode data.
Barcode with a low cell width has more chances to "lose cell" and in this case the error correction algorithm can only be used to read/restore data of barcode.
