Give the positional pattern custom radii. You can either set one radius for all corners or all positional eyes, or specify a radius for each corner of each eye.
Simple example:
<QRCode
value="https://github.com/gcoro/react-qrcode-logo"
eyeRadius={5} // 5 pixel radius for all corners of all positional eyes
/>Other examples:
// Radius for each eye
eyeRadius={[
5, // top/left eye
10, // top/right eye
5, // bottom/left eye
]}// Radius for each corner (array is: top/left, top/right, bottom/right, bottom/left)
eyeRadius={[
[10, 10, 0, 10], // top/left eye
[10, 10, 10, 0], // top/right eye
[10, 0, 10, 10], // bottom/left
]}// Include radius for the inner eye of the top/left eye
eyeRadius={[
{ // top/left eye
outer: [10, 10, 0, 10],
inner: [0, 10, 10, 10],
},
[10, 10, 10, 0], // top/right eye
[10, 0, 10, 10], // bottom/left
