Implement format options for images in labels

[strech345]

I dont find any documentation about the format expression for the text-field.
It is possible to change parameters for text. But is it also possible to edit image parameters like scale or color?
for example:
"text-field": ["format", ["image", "/station.png"], { "image-scale": 1.2 }]

@strech345 Thanks for reaching out. As of now, it is not possible to format images and edit the image parameters.
This sounds like a good addition. Do you want to take a first stab at it? If you are a first-time contributor, you can get started with our Contributing guidelines.

@sgolbabaei thanks for your response.
but whats about this feature? I thought someone is working on it or it was also merged into master?
#8604

Hi @strech345 as of now, the only options available to the format expression are font-scale, text-font and font-color.

As noted in #8904, we may add an image-scale option in the future. The font-scale option won't affect images in labels. As for changing image colors, that would probably require SDF images which are not currently supported by the the images in labels feature. These features are not on our roadmap so we have no timeline to implement them and it's not certain we even will. There's discussion in #8904 and #8604 about some of the difficulties around implementing these features.

That said, I think it's reasonable to re-open this ticket and use it as a feature request for image formatting options.

Is it settled now?
