Hello. How are you? Thank you for your update. I updated simple-qrcode 2.0 to 3.0. But I see this error. Class 'SimpleSoftwareIO\QRCode\QRCodeServiceProvider' not found I defined this code in 2.0. SimpleSoftwareIO\QRCode\QRCodeServiceProvider::class 'QRCode' => SimpleSoftwareIO\QRCode\Facedes\QRCode::class

How to solve this problem? And Can I use previous code to generate qr code?

Hi there. I am having an issue with the size of the QRCode. Some codes are of the size I gave them with zero margin, others have a margin (making the code smaller).

Example:

<img src="data:image/png;base64,{!! base64_encode(QrCode::format('png')->errorCorrection('Q')->size('100')->margin(0)->generate('DEMO-4444-55555-333-AAA-AAA')) !!}">
<img src="data:image/png;base64,{!! base64_encode(QrCode::format('png')->errorCorrection('Q')->size('100')->margin(0)->generate('DEMO-4444-55555-333-BBB-AAa')) !!}">
<img src="data:image/png;base64,{!! base64_encode(QrCode::format('png')->errorCorrection('Q')->size('100')->margin(0)->generate('DEMO-4444-55555-333-CCC-AaA')) !!}">
<img src="data:image/png;base64,{!! base64_encode(QrCode::format('png')->errorCorrection('Q')->size('100')->margin(0)->generate('DEMO-4444-55555-333-DDD-aAA')) !!}">
<img src="data:image/png;base64,{!! base64_encode(QrCode::format('png')->errorCorrection('Q')->size('100')->margin(0)->generate('DEMO-4444-55555-333-EEE-aaa')) !!}">
<img src="data:image/png;base64,{!! base64_encode(QrCode::format('png')->errorCorrection('Q')->size('100')->margin(0)->generate('DEMO-4444-55555-333-EEE-BBB')) !!}">

The result is:

Why is there a margin in the codes that have lowercase? I've run a few tests and everytime a smallcase letter appears, the code gets a margin. If I for instance remove the "DEMO-4444-5555-" from the start of the text, every code keeps the same size.

I have a problem while building the qr code, the error is "max (): Array must contain at least one element" I'm on a ubuntu server (laravel forge) with php 5.6.14 and laravel 5.1, is there any requirement besides the GD or something? thanks!

When a picture with transparency (PNG) is merged into a QR code, the four red boxes display the transparent part instead of the QR code. I can't do it like a demo.

$qrcode = 'data:image/png;base64,'.base64_encode(QrCode::format('png')->merge('https://avatars0.githubusercontent.com/u/7749926?s=400&v=4',
            .32, true)->errorCorrection('H')->size(500)->generate($url));

Hello. I need to build qrcode with shift-jis. So I have checked documentation and implemented with shift-jis. But I can see encoding error. How to solve it? https://prnt.sc/so9e5k https://prnt.sc/so9ehq

Instead of using the "simple" resize algorithm the resample algorithm can also be used when merging an image into the QR code. When the resampler is used, we get an anti-aliased merge and therefor a more pretty final result. The parameter that was added to the merge calls are always forced to be a boolean when they have to be set. This was done to be consistent with PHP's handling of "true-ness" for variables, while still having the internal variable as a strict type.

The workaround for not doing this is generating a large QR code with a merged image and finaly scaling that back. (Or letting the browser handle this step)

Another testcase was created to verify that setting the quality value in the ImageMerge class will actually yield a resampled and different result from the normal merge.

The calls implemented in the facade have been documented in the readme and have a small description in code (where applicable). Some minor changes were made in the in-code documentation to reflect name changes etc. I also made the indentation in the readme consistent. It appeared that mainly tabs were used, so all instances of 4 spaces have been replaced with 1 tab.

Hi,

I'm trying to send the QR code as an email, but it simply doesn't display in the email client. I have tried both gmail and yahoo.

To display the image I use <img src="data:image/png;base64, {{ base64_encode($qr) }} ">

To send the email I use the following:

$qr = QrCode::format('png')->size(200)->generate('http://google.com');
                Mail::send(
                    'emails.product_redeem',
                    [
                        'account' => $product->user,
                        'product' => $product,
                        'qr' => $qr
                    ],
                    function ($m) use ($product) {
                        $m->to($product->user->email, $product->user->username)
                            ->subject('Prospector theater - Redeem product')
                            ->from('[email protected]', 'Prospector theater');

                    }
                );

I'm using Laravel 5.1 to send the email: http://laravel.com/docs/5.1/mail

Any idea on how to come around this?

Hello,

when I echo the SVG qrcode, I also see this: <?xml version="1.0" encoding="UTF-8"?>

right before the qrcode is printed.

What could that be?

Thanks!

Hello,

When we want to generate a PNG QR Code, we're facing this issue :

"non-conforming drawing primitive definition `20' @ error/draw.c/DrawImage/3192"

You can find a debug printscreen : https://beta.easy-aide.ch/images/error.png

And here's the link to see it : https://beta.easy-aide.ch/public/pdf/certificat/28653/html

Any idea ?

Thanks a lot in advance

I need to generate the qrcode based on the selection of data in a SELECT, capture it via javascript and then generate the qrcode, is it possible to do this?

hello ,
im trying to genarate new QR Code and save it to my assets , im using this code : \QrCode::size(300)->generate( 'wifi:WEP/WPA;SSID;PSK;Hidden(True/False)', public_path('uploads/user_'.auth()->user()->resturant->id.'_wifi_'.'.svg') );

and its genart Qr Code for text not wifi where is the problem ?

Hello,

I am unable to find something like this in your documenation:

                    {!! QrCode::size(200)->link([
                    'https://' => 'website.com',
                    'param1' => $user->id,
                    'param2' => $user->email,
                    'param3' => $user->name,
                    ]) !!}

Which would then open a website with the below GET parameters upon scanning:

https://website.com?id&[email protected]&freddy

Is this not possible with your library?

As I can see helpers, but nothing in between apart from a single generate() method for a string.

Thank you!

Used version 2 and the qrcode had a good resolution. Now that I migrated to version 4, because I'm using php 8.1, the same qrcode is blurred.

Code used in both versions: <img src="data:image/png;base64, '.base64_encode($qrcode->format('png')->size(90)->margin(1)->generate($row['codigo'])).' ">

qrcode generated in version 2

qrcode generated in version 4

https://i.imgur.com/LCkKPHN.png

Did you notice that in version 4 the edges are a little blurred? They should be clear.

How to solve it?

Thanks.
