Re: [docbook-apps] Fitting tall images in PDF

[Mark Craig <mark.craig@gmail.com>]

Thanks David,

Hmm, it does seem to work… but, as Bob suggested, only if I set the height attribute to something specific.

In other words, height="100%" leaves the image spilling into the bottom margin.
height="7in" seems to work for my page size as long as the image is alone with no text.
