Hey, I'm trying to completely switch over to WebP and noticed some strange behaviour. Let's say I upload a PNG in Processwire of size 1280x800. $page->image->url ➝ correct URL (filename.webp) $page->image->width(800)->url ➝ correct URL (filename.800x0.webp) $page->image->width(1280)->url ➝ wrong URL (filename.1280x0.png), webp file is not generated $page->image->width(1280)->url(false) ➝ correct URL (filename.1280x0.webp) but webp file is not generated So: When I request a size that equals the original file, no WebP conversion is happening (no webp file is created, although a new PNG is generated (...1280x0.png)). When I use url(false), I get the expected URL but still the file is not generated. Also interesting: this issue is only occuring with PNG, not JPG. My Configuration: $config->imageSizerOptions('webpAdd', true); $config->imageSizerOptions('defaultGamma', -1); GD Pageimage::url Hook from here Also tried to output width(1280)->webp->url, it makes no difference I checked that the PNG version is not smaller in filesize (PNG=450KB, WebP (from other tool)=60KB) Tested with Processwire 3.0.148 and 3.0.160 dev I think this post is about the same issue and where I got the url(false) from. Setting 'useSrcUrlOnFail' => false inside $config->webpOptions results in correct output URL (filename.1280x0.webp), but still the file is not generated. So maybe the webp conversion fails? Apparently I see zero webp logs in logs/image-resizer.txt "Don't use resize" seems like a solution here but this is a generic approach in my code, sometimes uploaded images are simply already in the correct size. Any ideas how to fix this and always get dem sweet sweet WebP images? Or did I find a bug? Maybe @horst has an idea what the cause of this phenomenon could be? ? -
Hi there, I've been resizing some .png and got some pretty visible loss of quality. I attached those for comparison - around the Titanic (I know, they're big). I tried to find similar threads but couldn't find anything that helped - at least it made me install Horsts IMagick Image Sizer. foreach($detailrp->detail_repeater_bild as $pRetinaBild) { if ($pRetinaBild->width > $pRetinaBild->height) { // 3320px wide $pHighBild = $pRetinaBild->size(1660, 0); $pLowBild = $pRetinaBild->size(830, 0); } else { // 3220px high $pHighBild = $pRetinaBild->size(0, 1610); $pLowBild = $pRetinaBild->size(0, 805); } Anyone has any idea what causes this and how to solve it? Or should I just go with .jpg? Thx!

Hi, what I'm doing is this: <picture> <source srcset="<?php echo $page->section_three->main_img->first()->size(396,710)->webp->url; ?>" type="image/webp"> <img class="p_absoulte pp_block" src="<?php echo $page->section_three->main_img->first()->size(396,710)->url; ?>" alt=""> </picture> and for some reason it sometimes becomes this: <picture> <source srcset="/site/assets/files/1057/sektion3_bild-1.396x710.png" type="image/webp"> <img class="p_absoulte pp_block" src="/site/assets/files/1057/sektion3_bild-1.396x710.png" alt=""> </picture> It seems to be related to ->size(). When I don't use ->size() the webp Url is correct. I'm using the image-field inside a Fieldset(Page). Could that be a problem too? I just increased the output size by 2px and voila the webp url comes up. I deleted all variations (webp variation is present in correct size) changed it back to the original size and again: a png url. I also tried to rename the image and load it up agian. ...same behavoir. Thanks in advance guys

Can I convert uploaded images to PNG, GIF, BMP -> JPEG? Is there any function in the API that I can change the file type?

Hi, i'm quite new to processwire and have been getting on very well with it. I've noticed an issue when I upload an (exported from Photoshop) PNG with alpha via the image field. The original file was only 34kb, but after uploading its now 138kb? Can anyone help me figure out whats going on? I've searched Google and the forums, but could not find an answer. This doesn't seem to happen with JPEGS. Thanks in advance!

My client is uploading images via CK Editor into a textarea. The image type is a transparent PNG like the one attached (head-three.png) However when Processwire resizes this image there are little black line all through. See the 'head' image on this page - http://thinkingtosuccess.co.uk/business/#tab2 The original image is attached. How can we avoid these black lines causing the image corruption?

Hi, I'm getting some odd filesize issues with PNGs when uploading to Processwire. I've optimised a PNG down to 260kb using Save for Web + ImageOptim. Original image for upload Once it has been resized by Processwire the filesize skyrockets to 7mb+ Resized image by Processwire I've tried playing with the 'quality' setting but all it seems to do is degrade the quality of the image but the file size stays exactly the same. Does anyone know what might be happening here to make a resized PNG such a huge filesize compared to the original? Thanks!
