# Barcode Image Composer
The project is used to generate an image set with barcode, QR code and DataMatrix.
## Install Dependencies
```bash
pip install python-barcode pylibdmtx opencv-python pillow
```
## Supported Barcode Types
- UPCA
- QR Code
- DataMatrix
## Command-line Usage
```bash
$ imgcompose [-t TIMES] [-o OUTPUT] image-source
```
## Sample Code
```python
