A simple package to create fancy qr-codes with the help of the qrcode-package.
You may use \fancyqr just like the normal \qrcode (\fancyqr[<qr-options>]{<url>}). See the documentation. If you just want to create a simple qr-code, please refer to the minimal example.
fancyqr is actively developed by Florian Sihler (contact me at: florian.sihler@uni-ulm.de) under the GPLv3 License. I am very happy about every contribution (see CONTRIBUTING.md). You can find it on CTAN (https://www.ctan.org/pkg/fancyqr).
If you do want to hide a center square (e.g., because you want to embed an image), you can use \FancyQrDoNotPrintSquare{<x>}{<y>} 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{<name>}. 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{<keys>}):
| 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 option affecting error correction (low, medium, quartile, high). |
padding |
flag | 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 height option. |
|
tight |
flag | qrcode option adding no additional space around the qr-code. |
|
version |
[0..40] ∈ ℕ | 0 |
qrcode option affecting the size (tries to be as small as possible). |
width |
length | Alias for qrcode's height option. |
The defaults are set like this:
\fancyqrset{image padding=0,gradient=true,gradient angle=135,r color=teal,l color=purple}Footnotes

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. ↩
