```

*constructor*

**Parameters**

- `text` (`string`): The text string to encode in the QR code.
- `x` (`double`): The X coordinate of the lower-left corner of the QR code on the page, in user space units.
- `y` (`double`): The Y coordinate of the lower-left corner of the QR code on the page, in user space units.
- `width` (`double`): The width of the QR code, in user space units.
- `height` (`double`): The height of the QR code, in user space units.
- `errorLevel` ([`QRErrorCorrectionLevel`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/enum/QRErrorCorrectionLevel.md)): The error correction level for the QR code.
- `quietZoneSize` (`uint`): The size of the quiet zone (margin) around the QR code, in modules.
- `codeColor` ([`QRColor`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/QRColor.md)): The color of the QR code modules (the dark elements).
- `backgroundColor` ([`QRColor`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/QRColor.md)): The color of the background behind the QR code modules.
