    Hello Arjan,

    scale-to-fit scales the size of the image to the size of the viewport.
    Vieport's size is either set explicitely by attributes width and height
    or is determined from image's size (i.e. pixels times resolution).

    That is what the Recommendation says.

    What you probably need is

                    <fo:external-graphic src="url(img/large-image.gif)"
                                         content-width="scale-to-fit"
                                         width="100%"
                                         scaling="uniform"/>

    I.e. make the image as wide as the block is and scale its height proportionally.

    David
