I'm familiar with a method of exporting everything within a selected feature within Global Mapper using - Export > Export Raster/Image Format.
This takes everything within that feature and exports to a single image even though the project contains a collection of tiled rasters (sat images)
However I really want to learn how to do the same operation within QGIS - but I'm struggling as the only feature I can see that comes close is - Raster > Extraction > Clipper
But the 'Input file' selection makes you pick a specific raster - rather than everything? I would prefer not to have to merge the tiled rasters as I've noticed some degradation of quality, and due to the total size of rasters - memory becomes an issue with the processing of merging.
Is there anything I'm missing re exporting entire raster contents within a selected feature?
