Resolution/quality, different between versions

[tiagocaus]

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

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

How to solve it?

Thanks.

I had a similar case, and what I did was increase the 'size', while increasing the 'size' improved the definition. Regards

Not really sure why this is completed, the generated QR codes are blurry, the only 'workaround' is making them much larger then scaling them down which is really bad solution.
