TYPO3 Core

1. Prerequisites:
The attached custom ImageViewHelper must be implemented.

2. Steps to reproduce:
The custom ImageViewHelper must be called in a Fluid-Template like this:

<myExt:image image="{image}" alt="Foo" title="Bar" height="200" gifBuilderEffect="grey | gamma=2.0" 
    gifBuilderText="{align: 'right', offset: '-10,30', text: 'Hello World', fontsize: '35'}" fileExtension="png"  />

Where {image} must be a type of File or FileReference.

3. Actual Result:
- A Img tag is rendered
- The path in the src attribute points to an image in "/typo3temp/assets/images/"
- But the size of the rendered image in the assets folder is just 1px x 1px. So in fact no image is shown.

4. Expected result:
- A properly rendered image with GifBuilder Effects and GifBuilder Text.

5. Additional notes:
In TYPO3 12.4 the ImageViewHelper works.
The only difference in the TYPO3 12.4 version of the ImageViewHelper is the line 136 where the imageUri is assigned:

$imageUri = $gifBuilder->gifBuild();
