[Solved] rounding edges of QR code squares?

[owntheweb]

Hello,
I've had success creating a cool vanity QR code with rounded edges for my organization by generating a standard QR code, then applying a noise -> median effect in Photoshop to get the edges rounded among some other effects.



Photoshop is great, but I want to automate this. I found a great PHP library to generate QR codes. The part I don't get is the rounding of the hard edges.

I've seen other sites do it like this one.

Any thoughts on how to do this with ImageMagick+PHP? While familiar with GD, I just started playing with ImageMagick. It's like I'm drinking from a fire hose of possibilities right now! I'm reading this page and something with morpholigy looks potential. Newbie guidance is welcome.

Best regards,

Chris

Can you provide links to how you generate your basic qr codes?

Cool! Thanks for the prompt, helpful response. At the moment I've been creating QR codes at http://qrcode.kaywa.com/ at XL size, then doubling the size in Photoshop (while keeping sharp edges) before applying the median effect.

I'm taking a quick ImageMagick/PHP tutorial now and will respond with some samples if you don't beat me to it.

EDIT:

It looks like Imagick is the interface API I have access to. I'm reading up on all the functions and how to convert command lines into function calls.

You might be restricted with what Imagick can do; if so try with php exec( ) and the comand line. Some examples on my site.

I got it! Much more fun to be had, but here's what I have:

Code: Select all

<?php

$im = new Imagick("starter.png");
$height = $im->getImageHeight();
$width = $im->getImageWidth(); 
$im->resizeImage($width * 2, $height * 2, Imagick::FILTER_POINT, 0); 
$im->medianFilterImage(8);

header("Content-Type: image/png");
echo $im;

?>

Result:



I'm covered now. Thanks for the helpful info as I make steps forward on this.
