I am trying to crop a TIFF file in QGIS 3.2. What I am currently doing is going to Raster -> Extraction -> Clip Raster by Extent... . Then I type in my min and max x,y values. The new raster layer is the cropped image but all of my layers from the original TIFF image are gone. Attached is a screenshot of the before (noncrop.jpg) and after (crop.jpg) images. Note in the photos the layers are different for the Cresults raster vs. the Clipped (extent). How do I clip the Cresults TIFF image without losing its classes?
