   ></ngx-qrcode-generator>
   

Usage

The NgxQrcodeGeneratorComponent has the following input properties:

• background (string, default: 'white'): The background color of the QR code.
• backgroundAlpha (number, default: 1.0): The opacity of the background color (0.0 to 1.0).
• foreground (string, default: 'black'): The foreground color of the QR code.
• foregroundAlpha (number, default: 1.0): The opacity of the foreground color (0.0 to 1.0).
• level (string, default: 'L'): The error correction level of the QR code ('L', 'M', 'Q', 'H').
• mime (string, default: 'image/png'): The MIME type of the generated QR code image.
• padding (number or null, default: null): The padding around the QR code image (in pixels). Use null for default padding.
• size (number, default: 100): The size of the QR code image (width and height).
• value (string): The value to encode as a QR code.
• canvas (boolean, default: false): Whether to render the QR code as a canvas element (true) or an image element (false).

Example

Here is an example of using the NgxQrcodeGeneratorComponent:

<ngx-qrcode-generator
        [value]="'https://example.com'"
        [size]="200"
        [foreground]="'#ff0000'"
        [background]="'#ffffff'"
></ngx-qrcode-generator>

In this example, a QR code is generated with the value 'https://example.com', size of 200 pixels, red foreground color ('#ff0000'), and white background color ('#ffffff').

Notes

• This component requires the QRious library to be installed.
• Make sure to import and declare the component in your Angular module.
• Customize the input properties to achieve the desired QR code appearance.
• The generated QR code can be rendered as either a canvas or an image element, depending on the canvas input property.
