c# - Labelary QrCode PNG Image to String conversion -

i'm trying create zpl label using png image. png image qr code.

when go labelary.com/viewer.html converts png image type of string. sticking point don't know type of conversion it's using create new string.

according documentation @ https://www.zebra.com/content/dam/zebra/manuals/en-us/software/zpl-zbi2-pm-en.pdf should able convert png ascii hexadecimal string. however, when that, looks different labelary generates , doesn't work @ all.

can me figure out how convert png image string zpl can recognize? here's link image:

perhaps bypass image conversion , use qr code (^bq) of zpl directly?

an example zebra documentation (page 103-104):

^xa ^fo100,100 ^bqn,2,10 ^fdmm,aac-42^fs ^xz
