Hey,

I was wondering if there is an alternative to the default Processwire ImageSizer. Although it comes in really, really handy (I have actually never used any Content Management Framework that comes with a default Resize module) I am not quite content when it comes to resizing large images.

Check this image:

You can clearly see a difference in sharpness of both images, after resizing the image comes out a bit blurry (Yes, quality is on 100).  Has anybody else encountered this? If so, is there any good alternative (in form of a Module). 

Much love to anyone that's willing to help <3

Did you try different sharpening settings? Also that's not really a issue with processwire's imagesizer class, as the actual resizing is always done by external image processing libraries like gd or since 3.0 also imagemagick.

I can see! :)

You should read a bit about the images and our ImageSizer in the docs. What you are currently missing is, how to avoid the images caching. Add "forceNew" => true to your options array while developing. Otherwise you always will get the previously created and cached variation.

If you want to compare different options in one go, you also should read a bit about the suffix property.

Thank you for the response Horst.

I looked into the documentation, yet I didn't find anything concerning sharpening of images. That's why I came here to ask. I will mask this as solved. But could you please be so kind to link me the page in which the sharpening topic is covered? Thank you in advance.

Regards,

Jim

Hi Jim,

you are right, in the older documentation, there is only the older basic image handling described, but for most of it, you can switch to the new Docs, lately introduced with PW 3 branch, also if you use PW 2.6 / Pw 2.7

Here you go:

https://processwire.com/api/ref/pageimage/

https://processwire.com/api/ref/pageimage/size/

https://processwire.com/api/ref/pageimage/suffix/

      Hey folks,
      im pretty new to Processwire. A client of mine asked me to migrate his old (v2.5) Processwire Website. On his server its running on PHP 5.3 and i want to upgrade + migrate the site at the same time. I Downloaded the Site from his server to set it up locally, replaced the /wire directory, index.php and .htaccess with the files of the latest version. After that i changed the DB Connection details in the config.php, swapped to PHP 7.4 and now, when i open up the site on my localhost i get this error:
      compile(\ProcessWire\wire("config")->paths->root . "site/templates/includes/head.inc.php",array('includes'=>true,'namespace'=>true,'modules'=>true,'skipIfNamespace'=>true)))?> compile(\ProcessWire\wire("config")->paths->root . "site/templates/includes/header.inc.php",array('includes'=>true,'namespace'=>true,'modules'=>true,'skipIfNamespace'=>true)))?> compile(\ProcessWire\wire("config")->paths->root . "site/templates/includes/start_content.inc.php",array('includes'=>true,'namespace'=>true,'modules'=>true,'skipIfNamespace'=>true)))?> compile(\ProcessWire\wire("config")->paths->root . "site/templates/includes/footer.inc.php",array('includes'=>true,'namespace'=>true,'modules'=>true,'skipIfNamespace'=>true)))?> The page itself doesnt load, just a white space with this stuff on it
      I checked if the files exist, they do.
      I hope anyone can help me with that 🙂 Thanks in advance!

      These issues should be fairly easy for any intermediate to advanced ProcessWire developer to answer. I'm new to PHP and relatively new to ProcessWire and just need a bit of help. What I'm trying to do is bring in a couple of cards from my Projects page to display on my home page. I finally got the code right to bring in the cards but right now they're using my original images instead of my resized "variations". So firstly, I would like to know how to reference the variations of my images instead of using the original. Secondly, I need to grab only four of the cards from the Project page and not import in all ten. It should be just two small changes to my code to do these things (I would imagine). Here is the code I currently have for that section:
      <?php // https://processwire.com/api/arrays/ // check if the array of images has items if (count($pages->get("/projects/")->images)) : // get array of images from the field $images = $pages->get("/projects/")->images; $count = 0; // iterate over each one foreach ($images as $image) : $count++; $sectionText = $pages->get("/projects/")->get("paragraph_$count"); $img = $image; $buttonCode = $pages->get("/projects/")->get("url_$count"); ?> <span id="card<?php echo $count?>" class="card"> <img class="cardThumb" src="<?php echo $img->url; ?>" alt="<?php echo $image->description; ?> Thumbnail" /> <div class="cardBody"> <div class="cardText"> <h2><?php echo $img->description; ?></h2> <?php echo $sectionText; ?> </div> <div class="primaryBtn"> <a href="https://www.paypal.com/donate?hosted_button_id= <?php echo $buttonCode; ?> &source=url"> <button> <i class="fas fa-donate"></i> Donate </button> </a> </div> </div> </span> <?php endforeach; endif; ?> Thanks in advance for any help!

      Hello everyone. I am running a small technology blog, which is in WordPress. The main problem with my blog is that it does not open on any Windows 7 computer normally. I know Windows 7 has lost official support from Microsoft but still, there are plenty of users who still use Windows 7. The blog site is already 'HTTPS' protected but after opening in any browser, it shows 'not protected' next to the URL box. So, if I migrate all the site data to 'ProcessWare', will I get the same problem here too? Any kind of feedback would be greatly appreciated.
