Absolute path with IMG_RESOURCE

Question

I'm looking for a way to get an absolute path for an IMG_RESOURCE object in TypoScript. Since baseUrl is no real solution to me, simply add config.baseUrl = example.com isn't the thing I am accepting.

So, how could I solve something like this:

ogimage = FILES
ogimage{
    references {
        table = pages
        uid.data = page:uid
        fieldName = tx_csseo_og_image
    }
    renderObj = IMG_RESOURCE
    renderObj {
        file.import.data = file:current:publicUrl
        file.height < plugin.tx_csseo.social.openGraph.image.height
        file.width < plugin.tx_csseo.social.openGraph.image.width
        # this needs to be generated with an absolute URL
        stdWrap.dataWrap = <meta property="og:image" content="|" />
    }
}

I got a solution by myself. The point of the question was to not set the domain at any point at all. And have an absolute URL rendered from the FILES and IMG_RESOURCE objects, to be able to resize the image.

ogimage = FILES
ogimage{
    references {
        table = pages
        uid.data = page:uid
        fieldName = tx_csseo_og_image
    }
    renderObj = TEXT
    renderObj {
        typolink{
            parameter.stdWrap{
                cObject = IMG_RESOURCE
                cObject{
                    file.import.data = file:current:uid
                    file.treatIdAsReference = 1
                    file.height < plugin.tx_csseo.social.openGraph.image.height
                    file.width < plugin.tx_csseo.social.openGraph.image.width
                }
            }
            returnLast = url
            forceAbsoluteUrl = 1
        }
        wrap = <meta property="og:image" content="|" />
    }
}

This will generate a resized image via IMG_RESOURCE and then generate an absolute url to this generated image via typolink, that will be then wrapped inside a meta-tag.
