A simple package to create fancy qr-codes with the help of the [`qrcode`][qrcode]-package.
You may use `\fancyqr` just like the normal `\qrcode` (`\fancyqr[]{}`). See the [documentation](https://media.githubusercontent.com/media/EagleoutIce/fancyqr/gh-pages/build/fancyqr-doc.pdf). If you just want to create a simple qr-code, please refer to the [minimal example](qr-minimal.tex).
*fancyqr* is actively developed by *Florian Sihler* (contact me at: ) under the [GPLv3 License](LICENSE). I am very happy about every contribution (see [CONTRIBUTING.md](CONTRIBUTING.md)). You can find it on CTAN ().
If you do want to hide a center square (e.g., because you want to embed an image), you can use `\FancyQrDoNotPrintSquare{}{}` to hide a rectangle with radius x and y set from the center. If you choose this option, the default `\FancyQrRoundCut` that rounds cut corners can be changed with `\FancyQrHardCut`.
At the moment, there are six other styles (`flat`, `frame`, `blobs`, `glitch`, and `dots`) that you can load (locally) by using `\FancyQrLoad{}`. The default style is named `default` and can be 'reset' by `\FancyQrLoad{default}` or `\FancyQrLoadDefault`.
There are the following extra qr-options (you can set all of them with `\fancyqrset{}`):
| Option | Type | Default | Explanation |
| ----------------- | ----------- | :------: | ------------------------------------------------------------------------------------------------------------------------------------------ |
| `classic` | boolean | `false` | Use the classic qr-code style (black with flat rectangles, this loads the `flat` style). |
| `color` | color | | Disables the `gradient` and sets the qr color accordingly. |
| `gradient angle` | angle | `135` | Change the gradient angle. |
| `gradient` | boolean | true | Toggle the color gradient |
| `image` | LaTeX | | Automatically center an image (you have to care for the size and maybe adjust the `version` and `level` to keep the qr-code readable).[^1] |
| `image padding` | number | | Additionally hide blocks (x & y) around the image. |
| `image x padding` | number | `0` | Additionally hide blocks (x) around the image. |
| `image y padding` | number | `0` | Additionally hide blocks (y) around the image. |
| `l color` | color | `purple` | Set the top left gradient color. |
| `left color` | color | | Alias for `l color`. |
| `level` | L/M/Q/H | `M` | [`qrcode`][qrcode] option affecting error correction (low, medium, quartile, high). |
| `padding` | flag | | [`qrcode`][qrcode] option adding sufficient additional space around the qr-code. |
| `r color` | color | `teal` | Set the bottom right gradient color. |
| `random color` | colors | | Allow to set a random color pool to pick from. |
| `right color` | color | | Alias for `r color`. |
| `size` | length | | Alias for [`qrcode`'s][qrcode] `height` option. |
| `tight` | flag | | [`qrcode`][qrcode] option adding no additional space around the qr-code. |
| `version` | [0..40] ∈ ℕ | `0` | [`qrcode`][qrcode] option affecting the size (tries to be as small as possible). |
| `width` | length | | Alias for [`qrcode`'s][qrcode] `height` option. |
The defaults are set like this:
```LateX
\fancyqrset{image padding=0,gradient=true,gradient angle=135,r color=teal,l color=purple}
```
[^1]: The package will automatically calculate the required `\FancyQrDoNotPrintSquare` (you have to ensure that the qr-code still has enough information to be readable). Therefore, the image will not scale with the qr-code.
