I have a project on QGIS 2.18 which includes several raster and vectorial layers and need to export the full project as a high resolution Geotiff.
QGIS allows to export project as an image on print composer but it exports a low resolution image.
I am also able to export layer by layer but I need to export the full project as a single file.
Is there any plugin or approach that allows me to achieve that?
