How to crop a TIFF image

Question

Hopefully a simple question - I'm using ArcGIS Pro 2.2.0, and I've imported a TIFF map image over a base map. I'm wanting to crop the image, ideally using a polygon, but when I can't seem to do it. I've been trying to create a polygon through the edit menu, but with no luck. tiff ##crop image

If your "clipping" is only for visual purposes within the map, and you don't actually need a clipped tiff for some downstream analysis, you can use the following to achieve a sort of "virtual clip":

Create a very large polygon that covers the entire area covered by your map and then some.  Edit the polygon to remove the area in which you want to see the TIFF.  Think of this polygon as a "donut", with a hole in the middle.  Once you've got this polygon, you can use the Raster layer, Appearance, Masking tool to block out the areas covered by the polygon.  Select the TIFF in the Contents pane, then the Masking tool, and put a check in the donut polygon layer.

You'll now see that the tiff is masked.

ahhh! then it is somewhat confusing... since they should move the "clipping_geometry" up underneath the "rectangle" parameter since they are tied in

I guess I should  clip more

you will have to live with a rectangular extent

Au contraire, mon ami. The Clip Raster (Clip_management) tool has an option (clip_geometry) to clip to the polygon. Of course all rasters are rectangular, so what this does is set pixels outside of the polygon to a system-designated NoData value.
