[QGIS-Developer] Exporting large GeoTIFF files from print composer

[Matthias Kuhn]

Hi Andreas,

can you send us the warning literally (German or English)?

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.
