<p>Hi Andreas,</p>
<p>can you send us the warning literally (German or English)?</p>
<p>I remember an issue report (or gis.se question) about an
artificial limit that was formulated like a warning but was indeed
preventing from doing an export. Sounds pretty much like what you
are experiencing.</p>

<p>Hi,</p>
<p>I would like to export a large format QGIS print composer to a
GeoTIFF file.</p>
<p>Page format is 2.4 x 1.9 m and I would like to export at 300
dpi. It is for sending to a copy shop to print out for a trade
fair in our province.</p>
<p>I can successfully export at 270 dpi, but if I go beyond, QGIS
tells me that I may experience a "memory overflow".</p>
<p>My machine is 64bit (Win 7) and has 16GB of memory.</p>
<p>Is this an arbitrary artificial threshold value where QGIS
refuses to export? Would it potentially work, if the barrier
wouldn't exist? Could I somehow bypass this barrier?</p>
<p>Thanks if you have any idea.</p>
<p>Andreas</p>
