I don't think so. dmtx is for reading and writing Data Matrix 2D
barcodes. https://en.wikipedia.org/wiki/Data_Matrix

My iPhone camera recognizes QR and standard bar code.
https://en.wikipedia.org/wiki/QR_code It did not recognize the sample
Data Matrix 2D barcode on the above Wikipedia article.

However, 'Barcode to PC', an app for iOS, did recognize the sample, and
read it correctly.

However, for Long Wind's question:

> which package can convert barcode image to url?

I am going to assume you mean a standard linear bar code, such as an
International Standard Book Number (ISBN).
https://en.wikipedia.org/wiki/International_Standard_Book_Number

apt-cache search 'bar code'
apt-cache search barcode

should give you far more than you really want.

I have used zbar-tools to decode bar codes (ISBNs). I think the limit
on the process is the quality of the camera you use, which is why I went
to 'Barcode to PC'. Of course, that requires a mobile phone.
