# LiteCam for Python
[LiteCam](https://github.com/yushulx/cmake-cpp-barcode-qrcode-mrz/tree/main/litecam) is a lightweight, cross-platform library for capturing RGB frames from cameras and displaying them. Designed with simplicity and ease of integration in mind, LiteCam supports **Windows**, **Linux** and **macOS** platforms. It integrates easily with image processing frameworks like **OpenCV**, making it a versatile choice for developers.
## Features
- Capture RGB frames from video devices.
- Display live frames in a window.
- Draw contours and text directly on the displayed frames.
- Simple API for quick integration.
## Supported Platforms
- **Windows**
- **Linux**
- **macOS**
## How to Build the CPython Extension
- Development Mode
```bash
python setup.py develop
```
- Wheel Package
```bash
python setup.py bdist_wheel
```
- Source Distribution
```bash
python setup.py sdist
```
## Usage
### Basic Example
```python
import litecam
camera = litecam.PyCamera()
if camera.open(0):
window = litecam.PyWindow(
camera.getWidth(), camera.getHeight(), "Camera Stream")
while window.waitKey('q'):
frame = camera.captureFrame()
if frame is not None:
width = frame[0]
height = frame[1]
size = frame[2]
data = frame[3]
window.showFrame(width, height, data)
camera.release()
```
### API Overview
- **getDeviceList()**: Lists available video capture devices.
- **saveJpeg(filename, width, height, rgbdata)**: Saves the frame as a JPEG image.
#### PyCamera
- **open(index)**: Opens the camera with the specified index.
- **listMediaTypes()**: Lists supported media types.
- **setResolution(int width, int height)**: Sets the resolution for the camera.
- **captureFrame()`**: Captures a single RGB frame.
- **release()**: Closes the camera and releases resources.
- **getWidth()**: Returns the width of the frame.
- **getHeight()**: Returns the height of the frame.
#### PyWindow
- **waitKey(key)**: Waits for user input; returns `false` if the specified key is pressed or the window is closed.
- **showFrame(width, height, rgbdata)**: Displays an RGB frame.
- **drawContour(points)**: Draws contours on the frame.
- **drawText(text, x, y, fontSize, color)**: Draws text on the frame.
