will pass through any additional props to the underlying DOM node (<svg>
or <canvas>
). This allows the use of inline style
or custom className
to customize the rendering. One common use would be to support a responsive layout.
Note: In order to render QR Codes in <canvas>
on high density displays, we scale the canvas element to contain an appropriate number of pixels and then use inline styles to scale back down. We will merge any additional styles, with custom height
and width
overriding our own values. This allows scaling to percentages but if scaling beyond the size
, you will encounter blurry images. I recommend detecting resizes with something like react-measure to detect and pass the appropriate size when rendering to <canvas>
.
