Plugin configured to use Imgix, still spins up jobs "Optimizing image id XXXX"

[fgd007]

Describe the bug

I have ImageOptimize installed, and moved the configuration to Imgix recently. However, when touching the images (via an import or whatever) I see loads of "Optimizing image id XXXX" jobs being fired. They all fail. The whole image optimization step should be done by Imgix?

Seems like a bug? I saw this issue which seemed like a similar issue, but that one should be fixed and merged already.

This is the content of one of those failed jobs:

Edit: most jobs don't fail. They run without issues. But are they necessary?

To reproduce

• Configure Imgix to use Craft GD/Imagemagick
• Change it to Imgix
• Add of edit assets

Expected behaviour

I would expect that the image optimizing step is done by Imgix and that no additional job is necessary.

Screenshots

Versions

• Plugin version: 4.0.5
• Craft version: 4.5.10

[fgd007]

On a further update: Some of these jobs fail. For instance when a image is very big (7000px x 4000px). I don't get it why this should be problem? Imgix should deal with that? A thumbnail version of the image in the Asset library loads an Imgix version successfully...

The failing asset shows: "This is not an image that can be manipulated"

Can you please check your logs, or the details from the Queue utility, and give me the actual errors that are being logged?

[khalwat]

Also did you update your version of nystudio107/craft-imageoptimize-imgix to the latest version?

[fgd007]

Running ImageOptimize 4.0.5. I bumped version of craft-imageoptimize-imgix to 4.0.3 manually. It didn't change anything.

When I run ddev craft image-optimize/optimize/create-asset on certain images I get this:

2023-11-22 14:45:38 [queue.INFO] [craft\queue\QueueLogBehavior::beforeExec]  [45622] Optimizing image id 254570 (attempt: 1, pid: 7710) - Started {"memory":5934592}

When I run ddev craft image-optimize/optimize/create-asset on other images, it is logging these steps:

[khalwat]

The placeholder images are generated via PHP regardless of your transform method, and it looks like your PHP install is running out of memory attempting to create the placeholder images for this very large image.

If you're not using the placeholder images, you can disable their generation via the config file:

https://github.com/nystudio107/craft-imageoptimize/blob/develop-v4/src/config.php#L58

[fgd007]

When I disable all settings, it still tries to transform images locally. I don't understand why Imagemagick / local transforms are needed when all transforms can be done by Imgix. Can you clarify @khalwat?

My bad -- it looks like that setting may only be exposed in the config file:

https://github.com/nystudio107/craft-imageoptimize/blob/develop-v4/src/config.php#L59

Ah, I was too quick and thought it was the setting Create Placeholder Silhouettes.

Verified this custom config setting, and it works now!

But to conclude with replying to my initial question: Yes, even when using Imgix as provider, it will spin up jobs in the queue.

[fgd007]

Disabling the placeholders kills the color palette feature (see also issue #175).

Imgix is also able to generate a color palette for an asset, but I don't see this endpoint being used by craft-imageoptimize-imgix. Would be a nice feature though.

[khalwat]

Right because it's pre-generating the URLs so that it doesn't have to ping Imgix each time to generate them. Arguably that could be optimized.
