Image TransformSourcePath

[tim-thaler]

Hello Kyle,
thank you for your work on this plugin!

I only use the local file storage and I found that if I use "@webroot/files" in the public URL field, I get an error because the file can't be retrieved.

Transform.php (Row 168)
$masterImage = $asset->url;

needs to be changed to, but I'm not sure

$masterImage = $asset->getImageTransformSourcePath();

Can you provide a bit more information such as your Craft CMS version, PHP version, and what Image Driver you're using. You can get this info from Utilities -> System Report -> Application Info.

I'm not able to recreate the issue on Craft 3.5.14 with PHP 7.2.1. Using getImageTransformSourcePath() seems like a better option than the current implementation but I want to make sure it will fix your issue before I release the fix and close this issue.

When I set my Base URL field to @webroot/images I'm not recieving any errors before or after changing to the getImageTransformSourcePath() method.

{% set transformedImageUrl = "/jitter/v1/transform&id=" ~ entry.image[0].id ~ "&w=150&ar=1:1&m=fit&fm=gif&q=10" %}
<img 
    src="{{ transformedImageUrl }}" 
    srcset="{{ craft.jitter.srcset(entry.image[0], [
        { w: 300, h: 250, },
        { w: 768, ar: "16:9", },
        { w: 1024, ar: "16:9", q: 100 },
    ]) }}" 
    loading="lazy"
    width="1024"
/>

Hi Kyle, I had further investigations.

First thing was more a problem of my server configuration. If you run the system behind a .htaccess protected area, you need to make sure that the server itself can call the image source without getting 401 - permission denied ;-)

Second thing what I found is that if you have a DOCUMENT_ROOT with "." your regex for the contenttype doesn't work properly.
Example: /var/www/example.com/public/images/image.jpg

Instead of:

preg_match("/(\..*)$/", $existingFile, $matches);
$contentType = ltrim($matches[0], ".");

Needs to be:

preg_match("/(\..{1,4})$/", $existingFile, $matches);
$contentType = ltrim($matches[0], ".");

Now it works great!
