TYPO3 Core

please try {f:uri:image(image:image)}. That should take all settings from the reference into account.

{f:uri:image(image:image)}

testet:

 {f:uri:image(image:image)}
 {f:uri:image(image:{image})}
 {f:uri:image(image: '{image}')}
 <f:uri.image image="{image}"/>

all = nothing

The same for <f:image image="{image}" />"?

What kind of object is {image}?

I'm not sure how to determine the object type.

<f:debug>{image}</f:debug> gives the following:

The Object is made with Flux:

<flux:field.inline.fal name="image" required="true" showThumbs="true"/>

and the image-output:

{v:content.resources.fal(field: 'image') -> v:iterator.first() -> v:variable.set(name: 'image')}
<f:image class="imageoutput" treatIdAsReference="1" src="{image.id}" title="{image.title}" alt="{image.alternative}" crop="{image.crop}"/>

The "crop"-value is set with the backend image manipulation editor.

Looks like {f:uri.image(crop: image.crop, src: image.id)} should work for your use-case. treatIdAsReference:1, isn't needed as the id is the identifier of the file itself and not of the reference.

What exact version of TYPO3 are you using? Latest of the 7.6 branche?

{f:uri.image(crop: image.crop, src: image.id)} works!

I'm using the 7.6.14
For me the documentation seems not clear enough to solve this on my own :)

Thank you!
