PyXing is supposedly a Python port of the popular Java , but the initial and only commit is 6 years old and the project has no readme or documentation whatsoever. Furthermore, refers to Ubuntu 8. This facilitates the process of deciphering the code for programs or the smartphone later on. Although qrtools requires zbar and is thus not pure python, it does indeed work now.
However, it is excellent for reading codes at the command line. However, if you want to specify the size of each dot in the code, set Mode to Module size, then in Module size pixel define the number of pixels to form a dot. If you are using generic labels then the Avery code that your labels are compatible with should be shown on your box or packet of label sheets. I have no idea how to do this what is a Vcard and Sms.
