to_string ( encoding = 'unicode' ) Pure Python PNG You can convert the SVG image into strings using the to_string() method.Īdditional keyword arguments are forwarded to ElementTrees tostring(): img. The resulting SVG: import qrcode qr = qrcode. This helps to fine tune the root element of The QRCode.make_image() method forwards additional keyword arguments to the Two other related factories are available that work the same, but also fill theīackground of the SVG with white: make ( 'Some data here', image_factory = factory ) SvgFragmentImage else : # Combined path factory, fixes white space that may occur when zooming factory = qrcode. SvgImage elif method = 'fragment' : # Fragment factory (also just a set of rects) factory = qrcode. Or in Python: import qrcode import if method = 'basic' : # Simple factory, just a set of rects. Qr -factory=svg-fragment 'Some text' > test.svg Image, you can use the factory that combines as a path (recommended, andĭefault for the script) or a factory that creates a simple set of rectangles.įrom your command line: qr -factory=svg-path 'Some text' > test.svg You can create the entire SVG or an SVG fragment. Keyword argument is a valid option for the QRCode class for more advanced The Python examples below use the make shortcut. You can encode as SVG, or use a new pure Python image processor to encode to (the default is 4, which is the minimum according to the specs). The border parameter controls how many boxes thick the border should be The box_size parameter controls how many pixels each “box” of the QR code ERROR_CORRECT_H.Ībout 30% or less errors can be corrected. ERROR_CORRECT_QĪbout 25% or less errors can be corrected. ERROR_CORRECT_M (default)Ībout 15% or less errors can be corrected. The following four constants are made available on the qrcodeĪbout 7% or less errors can be corrected. The error_correction parameter controls the error correction used for the Set to None and use the fit parameter when making the code to determineįill_color and back_color can change the background and the paintingĬolor of the QR, when using the default image factory. The QR Code (the smallest, version 1, is a 21x21 matrix).

The version parameter is an integer from 1 to 40 that controls the size of make_image ( fill_color = 'black', back_color = 'white' ) ERROR_CORRECT_L, box_size = 10, border = 4, ) qr. QRCode ( version = 1, error_correction = qrcode. save ( 'some_file.png' ) Advanced Usageįor more control, use the QRCode class. make ( 'Some data here' ) type ( img ) # img. Or in Python, use the make shortcut function: import qrcode img = qrcode. Information encoded can be made up of any kind of data (e.g., binary,įrom the command line, use the installed qr script: qr 'Some text' > test.png The code consists ofīlack modules arranged in a square pattern on a white background. Readability and comparatively large storage capacity.

That pillow is installed and can be used for generating images: pip install 'qrcode' What is a QR Code?Ī Quick Response code is a two-dimensional pictographic code used for its fast A standard install is just: pip install qrcodeįor more image functionality, install qrcode with the pil dependency so A standard install uses pypng to generate PNG files and can also render QRĬodes directly to the console.
