Re: Scaling images
Add the height attribute to the external-graphic element. Now, I was expecting that height=100% would work in this case but it doesn't seem to be the case so either there is a bug in the code or in my understanding. But if you specify an absolute value, say height=150mm, then it works. On Mon, Feb 24, 2014 at 2:54 PM, markus.sticker.e...@zf.com wrote: But it fails also.

AW: Scaling images
Ok. But scaling has in our case to be dynamic. So I even can calulate the maximum availiable space. Will there be a bug created in the Jira? What I mean is, will it be fixed by the apache team or should I build a workaround? Von: Luis Bernardo [mailto:lmpmberna...@gmail.com] Gesendet: Dienstag, 25.

Re: AW: Scaling images
For you specifying an absolute height in the block-container or in the external-graphic should be the same (in terms of complexity). So I don't see the need for a workaround. But I will confirm whether the fact that content-height does not seem to take the height from the block-container is a bug, and then I will create a Jira ticket if needed.
