qr-code-generator

To generate a QR code from a URL or text, run the Python script with your target string, such as passing a URL to the command line interface. This encodes the data into a QR code image using the qrcode and Pillow libraries, outputting a scannable graphic for apps or documents.

WiFi credential and vCard QR codes can be created by inputting the specific contact or network data into the generator. It encodes WiFi details, vCards, emails, geographic coordinates, and calendar events, producing customized QR codes suitable for event ticketing or product packaging workflows.

Batch QR code generation from CSV or JSON data is handled by processing multiple entries through the script with automated naming conventions. It reads structured input files, encodes each row or object into a QR code, and exports the resulting images in bulk for scalable workflows.

This QR code generator supports exporting to SVG, PDF, EPS, PNG, and terminal formats. It leverages the segno library to render the encoded data into vector or raster outputs, allowing integration into branded documents, scalable packaging designs, and application interfaces.

To add a custom logo or change colors, configure the generator's styling parameters for foreground, background, borders, and optional logos. It applies these customizations to the QR code rendering process using Pillow, producing branded image outputs with specific error-correction levels.

You need Python and the OpenClawCLI integration to set up the environment for this QR code generator. It requires installing specific Python dependencies including qrcode, Pillow, and segno, establishing the runtime environment needed to execute the data encoding scripts.
