WriterSetting.MinWidth for DataMatrix

Post by Document Partner » Fri Feb 17, 2012 11:28 AM

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

Hello,
could you state, why it is not recommended?
are there any common pitfalls in using barcodes with a low cell width? 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.
