# QR Code
|
|
||||||
|
|
||||||
Generate QR codes from text/URLs and decode QR codes from images.
|
|
||||||
|
|
||||||
## Capabilities
|
|
||||||
|
|
||||||
- Generate QR codes from any text, URL, or data
|
|
||||||
- Customize QR code size and error correction level
|
|
||||||
- Save as PNG or display in terminal
|
|
||||||
- Read/decode QR codes from image files (PNG, JPG, etc.)
|
|
||||||
- Read QR codes from screenshots
|
|
||||||
|
|
||||||
## Requirements
|
|
||||||
|
|
||||||
Install Python dependencies:
|
|
||||||
|
|
||||||
### For Generation
|
|
||||||
|
|
||||||
```bash
|
|
||||||
pip install qrcode pillow
|
|
||||||
```
|
|
||||||
|
|
||||||
### For Reading
|
|
||||||
|
|
||||||
```bash
|
|
||||||
pip install pillow pyzbar
|
|
||||||
```
|
|
||||||
|
|
||||||
On Windows, pyzbar requires Visual C++ Redistributable.
|
|
||||||
On macOS: `brew install zbar`
|
|
||||||
On Linux: `apt install libzbar0`
|
|
||||||
|
|
||||||
## Generate QR Code
|
|
||||||
|
|
||||||
```bash
|
|
||||||
python scripts/qr_generate.py "https://example.com" output.png
|
|
||||||
```
|
|
||||||
|
|
||||||
Options:
|
|
||||||
|
|
||||||
- `--size`: Box size in pixels (default: 10)
|
|
||||||
- `--border`: Border size in boxes (default: 4)
|
|
||||||
- `--error`: Error correction level L/M/Q/H (default: M)
|
|
||||||
|
|
||||||
Example with options:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
python scripts/qr_generate.py "Hello World" hello.png --size 15 --border 2
|
|
||||||
```
|
|
||||||
|
|
||||||
## Read QR Code
|
|
||||||
|
|
||||||
```bash
|
|
||||||
python scripts/qr_read.py image.png
|
|
||||||
```
|
|
||||||
|
|
||||||
Returns the decoded text/URL from the QR code.
|
|
||||||
|
|
||||||
## Quick Examples
|
|
||||||
|
|
||||||
Generate QR for a URL:
|
|
||||||
|
|
||||||
```python
|
|
||||||
import qrcode
|
|
||||||
img = qrcode.make("https://openclaw.ai")
|
|
||||||
img.save("openclaw.png")
|
|
||||||
```
|
|
||||||
|
|
||||||
Read QR from image:
|
|
||||||
|
|
||||||
```python
|
|
||||||
from pyzbar.pyzbar import decode
|
|
||||||
from PIL import Image
|
|
||||||
data = decode(Image.open("qr.png"))
|
|
||||||
print(data[0].data.decode())
|
|
||||||
```
|
|
||||||
|
|
||||||
## Scripts
|
|
||||||
|
|
||||||
- `scripts/qr_generate.py` - Generate QR codes with customization options
|
|
||||||
- `scripts/qr_read.py` - Decode QR codes from image files
