<p>it this limited implemented for all platforms? I remember that while Windows had always problems in exporting large maps objects/layouts Linux had always performed well.</p> QGIS Application - Feature request #10822: Print composer - allow tiled raster image exports for large resolution exportshttps://issues.qgis.org/issues/10822?journal_id=628422015-07-09T08:31:18ZArthur Bogardarthur@digitaliseducation.com

<p>I have Ubuntu 15.04 with QGIS 2.4 and also receive this error when attempting to export a file of dimensions: 213390 x 106696</p>
<p>My workaround is to export 32 separate tiles and then combine the tiles using GDAL. Would be much easier if I could just export this from QGIS directly.</p> QGIS Application - Feature request #10822: Print composer - allow tiled raster image exports for large resolution exportshttps://issues.qgis.org/issues/10822?journal_id=766442017-04-30T22:47:47ZGiovanni Manghigiovanni.manghi@gmail.com
