For Example this part will get downsized to a fraction of its original size:
<text left="1091" top="621" width="37" height="167" angle="
270" offset-x="37" offset-y="0" font-face="Arial" font-size="8">Example Text</text>
I guess it´s because of the rotation... Preview in composer is correct!
Any ideas ? My guess is a bug in size calculation combined with rotation.
