[SPAM] Re: [xep-support] [SPAM] Image scaling to fit available height

[David Cramer]

  Hi Jan,
In fact, the xsl-fo 1.1 spec provides a mechanism to handle just your 
situation. You can set content-width="scale-down-to-fit" and the fo 
renderer will know to scale your image down proportionally only if 
there's not enough room for it. Sadly, however, xep does not yet support 
scale-down-to-fit, though I believe Antenna House and FOP do.

There's a thread discussing the issue that starts here:
http://services.renderx.com/lists/xep-support/6210.html

And concludes here, with Kevin providing a hack to workaround this 
limitation in xep:
http://services.renderx.com/lists/xep-support/6225.html

I'm glad to see you bringing up the situation. I had some trouble 
convincing Kevin that it is a legitimate use case. I would still very 
much prefer for xep to support scale-down-to-fit than to resort to the 
post-processing they suggest.

Good luck,
David

I've tried to switch corresponding attribute values, but if the image is taller, I am getting [error] no space for an element, trying to recover - and this image is missing in the output.
