/**

> The QPixmap class helps hold an image in the form of off-screen image representation.

* **This class is a JS wrapper around Qt's [QPixmap class](https://doc.qt.io/qt-5/qpixmap.html)**

A `QPixmap` provides ability to store an image in the memory.

### Example

```javascript
import { QPixmap } from "@vixen-js/core";

const imageUrl = "path/to/png";
const pixMap = new QPixmap(imageUrl);
```
