<p>Hi Matthias,</p>
<p>Here is more info:</p>
<p>First, I receive a warning saying: "To create image 28346x22440 requires about 1908 MB of memory. Proceed?" with an OK / Cancel button.</p>
<p>Then I press "OK"</p>
<p>A dialog appears where I can choose where to store the raster file.</p>
<p>Then a dialog titled "Image export options" appears, where I could do various settings, like - again selecting the dpi, width and height and I could "Crop to content".</p>
<p>I leave all settings as they are by default and press "Save".</p>
<p>Then the final and blocking error message dialog is:</p>
<p>"Trying to create image #1 (28346x22440 @ 300dpi) may result in a memory overflow. Please try a lower resolution or a smaller papersize".</p>
<p>Then I can only press "OK" and the image isn't exported.</p>
<p>Thanks for having a look at this,</p>
<p>Andreas</p>

<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>
