    Hello Marc,

    M> Thank for answer,

    M> I'll try to be more explicit.
    M> I have a graphic who is 30cm width, and my page is only 20cm.
    M> But this graphic is an XML file and sometimes it is only 10cm width.
    M> When it is 30cm, I want to reduce it to 20cm, but when it is 10cm I

    M> In the XML file I don't know the size of the graphic.

    Try this code:
      <fo:external-graphic content-width="scale-to-fit"
                           width="20cm"
                           content-height="100%"
                           scaling="uniform"
                           src="url(./Ann7CnvTriP51.gif)"/>

    It should scale down everything that is wider than 20cm, but leave all
    other images intact.

    M> I try this, but it's the same I have an overflow:
    M> <fo:external-graphic content-width="scale-to-fit" scaling="uniform"
    M> src="url(./Ann7CnvTriP50.gif)"/>

    Yes, since you haven't set explicit width as I recommended in my
    previous post you still have an overflow.
