Recently started using QGIS 2.18, for basic mapping. I am using Swedish GEO-agancy data shapefiles as bottom layers with my own shapefiles as toplayers (EPSG:3006 (SWEREF99 TM)), including a GPX file (EPSG:4326 (WGS84)) manipulated by GPXeditor.
When using the Print Composer to export the map as a GeoTIFF I can not choose a "Reference Map" under "Composition -> Export Settings".
So the exported TIF does not include any georeferencing when opening it in ex. Avenza on my phone. Also the map on my phone is already 2/3 zoomed in, I can't see an overview by zooming out. I can zoom in though.
Why can't I set a Reference Map ? Is it because all layers are EPSG3006 exept the GPX waypoints that are EPSG:4326?
Or is there some other reasone the map does not export a GeoTIFF.
