OQRCode Generator

• The input string is the content of the QR Code and can be anything from simple hyperlinks to Wi-Fi credentials and vCards
• The version (1-40) determines the size and data capacity of the QR Code. If you run into a "code length overflow" error, try increasing the version number. This encoder uses ECC level "H" and operates in "8-bit binary" mode.
• The "quiet zone" specifies an area around the QR Code with a minimum width of 4 modules to ensure readability. It should be in the same color as the light parts of the matrix.
• Draw circular modules renders each QR Code pixel (=module) as a filled disc with the given radius instead of a square. Additionally the finder and alignment patterns can be rendered as circles, too.

If a logo is selected, a space with the given scale (percentage of the total QR Code size) will be cleared and the logo fitted in. Clearing the logo space can be skipped which will result in the logo just being slapped over the QR Code.

Since logos are not part of the specification and instead they're just abusing the error correction capacity (30% in ECC mode "H"), you need to make sure that the code remains readable.

The logos in the list are just a tiny selection from Simple Icons - just ping me if you're missing something. Alternatively, you can just replace the logo code by yourself by editing the SVG source.

The color settings for the individual parts of the QR Code. These settings are not concrete as you can easily edit the SVG source and change them in the "defs" section, for example to add a gradient.
If the transparent option is set, the "light" parts of the QR matrix will be omitted from the output.

Please note that while it is possible to invert the colors for the dark and light parts it's not recommended as not all readers are able to handle inverted colors.
