Subject: Re: [docbook-apps] Re: <graphic> scaling

Ah, then you need to add one more attribute:


This sets the image height to its natural size, but it is further
constrained by the other two attributes that set the viewport to the
available width, and scale it down to fit it.

In XEP and Antenna House, this will keep the image at its natural size
unless it is too big, in which case it will shrink it to fit.  It doesn't
work in FOP.

Yes, even though FOP doesn't support all the image properties, the DocBook
XSL stylesheets output the right properties.  So you may get warnings about
unsupported properties when using FOP.
