PiQR 0.1.6

A Python library for generating and displaying QR codes.

Project Title

QR generator tool that returns either a PNG, postscript file, or a postscript object of an input string

Description

I created this QR generator tool with the express purpose of generating custom QR codes for PDFs without the need for an adobe subscription. The returned postscript data can be used to place into a prewritten postscript file and then converted into a PDF using ghostscript.

Getting Started

Dependencies

• In order to generate a QR image you will require both cv2 and numpy

  pip install opencv-contrib-python
  pip install numpy
  

Installing

• Clone the repo

  git clone https://github.com/PimpDiCaprio/PiQR.git
  

• Installing with pip

  pip install PiQR
  

Executing program

• How to run the program
• Step-by-step bullets

from PiQR import PiQR

# define the input string for the qr code
qr_string = 'Test Input'

# generate qr binary for the input string
qr_output = PiQR.generate_qr(qr_string, correction_level='Medium')

# the following options are available for displaying or saving the qr code

# display the qr code
PiQR.show_png(qr_output)

# save the qr as a png
PiQR.make_png(qr_output, 'test.png')

# write a postscript file containing the qr
PiQR.write_ps(qr_output, 'test.ps')

# return a postscript object in string form for placement into a ps file
ps_string = PiQR.return_ps(qr_output)
