I am looking to add a new QR Code style which will look like the following

Users will only be able to update the inner color of the eye.

Full Description of the new required designs is described in the following screenshot

I am looking for an optimal way to achieve this task.

Thanks in advance

Hello, I would like to ask if in your source code there is a file called "Modules.php" A colleague tells me that on his website, passing wordfence, a path appears: "wp-content / mu-plugins / nue / vendor / bacon / bacon-qr-code / Modules.php" detected as malware.

I have downloaded your .zip and I don't see that it has that file. This installation is normal in mu-plugins / nue

Hi @DASPRiD,

When I generate a QR Code as follows I get a valid image.

$renderer = new \BaconQrCode\Renderer\Image\Png(); $renderer->setHeight(256); $renderer->setWidth(256); $writer = new \BaconQrCode\Writer($renderer); $writer->writeFile('localhost/preinscription/1/f3a450d9545685097a486e7446730d9f/', 'qrcode.png', Encoder::DEFAULT_BYTE_MODE_ECODING, ErrorCorrectionLevel::L);

However when I increase the error correction level to ErrorCorrectionLebel::H I end up with an image that both my automated reader and my Android Barcode Scanner cannot read. Do you have any idea what could be the issue?

Thanks!

Fixes an HHVM bug that results with the following exception: max(): Array must contain at least one element.

Please merge and release a 1.0.1. We use this heavily as a dependency. Thank you!

Since the last version that added a new dependency to run tests I can not package it in Debian, I made one adjustment to allow me to --exclude-group integration and just have to remove use MatchesSnapshots; on Debian.

I also made changes to make everybody happy, exclude the tests from composer archives and allow me to have them in Debian

Hi!

I'm using the sprain/php-swiss-qr-bill library to generate QR-ESRs. Generating a single QR-ESR takes ~5 seconds (or more).

Then I started the profiler and debugged it manually until I found that only the BaconQrCode\Encoder::chooseMaskPattern needed nearly all of this time. The time for PDF rendering etc. is nothing compared to this single method.

https://github.com/Bacon/BaconQrCode/blob/master/src/Encoder/Encoder.php#L233-L252

My question, is there a possibility to pass "some arguments" to make it faster to generate the QR code?

public static function getDataMaskBit($maskPattern, $x, $y) { ... case 4: $intermediate = (BitUtils::unsignedRightShift($y, 1) + ($x / 3)) & 0x1;

the term $x / 3 must not be an integer. Can you please round the term?

With the addition of the 'return' statement, it facilitates the creation of unit tests for QR Code generator. Allowing you to test whether the file was generated or not.

Process hangs forever

I'm trying to write a new Module Renderer for Eye(internal and external) in order to get Square with Rounded Corner(not circle) but not sure how to get that.

I mean, using matrix logic how to achieve this?

For Circle I use this one:

      ->move(3.5, 0)
      ->ellipticArc(3.5, 3.5, 0., false, true, 0., 3.5)
      ->ellipticArc(3.5, 3.5, 0., false, true, -3.5, 0.)
      ->ellipticArc(3.5, 3.5, 0., false, true, 0., -3.5)
      ->ellipticArc(3.5, 3.5, 0., false, true, 3.5, 0.)
      ->close()

      ->move(2.5, 0)
      ->ellipticArc(2.5, 2.5, 0., false, true, 0., 2.5)
      ->ellipticArc(2.5, 2.5, 0., false, true, -2.5, 0.)
      ->ellipticArc(2.5, 2.5, 0., false, true, 0., -2.5)
      ->ellipticArc(2.5, 2.5, 0., false, true, 2.5, 0.)
      ->close()

Should I focus on replacing ellipticArc with a combination of line() and curve()?

Expected result:

There are no instructions on how to add a URL and Email?

$renderer = new ImageRenderer(
      new RendererStyle(400),
      new SvgImageBackEnd()
    );
    $writer = new Writer($renderer);
    $qr =  $writer->writeString($this->phone);

I can write the phone number or the email or the URL but how can you combine all of these?

My client's web hosting provider sucks, and they don't have support for Imagick, even though they are promising it will be added.

I'm generating QR codes for payment, which is added into email body. And email client's do not have nice support for SVG. So I need old-school GD support.

However, GD has limited sets of functions. I believe, that it is OK, when that backend will have also limited sets of features. So this is not supported:

• Any roundness like DotsModule, RoundnessModule or SimpleCircleEye
• Gradients

And because GD does not support Paths like Imagick or SVG do, I need to generate a bit different paths, so they are not so complex.

For Laravel 8, running PHP 7.4 or PHP 8.

I have installed the simplesoftwareio / simple-qrcode plugin. It worked fine in PHP 5.4 but we are trying to upgrade.

Now when I upgrade and try to use the code to generate the QR code, we get this error.

"You need to install the imagick extension to use this backend".

~/src/Renderer/Image/ImagickImageBackEnd.php:64

But imagick IS INSTALLED. I found many other people with this same problem (so I'm not crazy here) and they all resolved in downgrading to BaconQrCode version 1.0.3. But Laravel 8 won't let me do that, because of requirements.

So I'm just stuck and wondering if this can be fixed?

I'm generating a QR from a URL that has 48 ASCII chars and using Q redundancy, which should mean the total data size is 60 bytes. For that amount of data, this library generates a 37x37 version 5 QR. Looking at this chart, I can see that the capacity of a version 5 does correspond to 60 bytes in "binary" mode, but version 4 can accommodate 67 bytes in "alphanumeric" mode. This chart shows that that this set includes :, ., and / which is all that's needed for URL support, but it does not support lower-case chars. So now I'm mystified because I have a QR generated by a different system that is a version 4 and successfully encodes my URL containing lower-case chars with the correct degree of redundancy.

I suspect that this is due to the other system supporting mode optimisation, where the data can be split into chunks, each with a different encoding mode, for example if my URL contains https://www.example.com/ABC1234567890/XYZ, this could be encoded as a byte-mode chunk of https://www.example.com followed by an alphanumeric chunk of /ABC1234567890/XYZ, or possibly even finer chunks if 1234567890 could be dropped to numeric mode.

This page has an excellent demonstration of mode optimization along with a detailed description of how it works.

Do you have any plans to implement this optimisation so we can have smaller QRs?
