Export Raster and Clip

[EM0]

I'm looking for some help with the export raster/clip option with my map. You can see in the photo below there is a raster image I tried to export using a clip poly - but the clip doesn't seem to stick to the polygon edges, even though I have checked off the 'Use input features for clipping geometry'. I also tried to change the NoData value to 255, but this also removes the yellow background of the scanned image.

Could someone tell me what I am missing to clip/export the raster with a polygon correctly?

a raster will be rectangular in shape, always

Let's assume you are usin a polygon as the clipping feature.  The raster cells that don't fall within the bounds of the polygon will be filled with nodata values.

Ditto if the polygon is used to clip, but you are keeping the outside

Got it, but how do I remove the black cells in the raster image after the clip occurs? The one option I have tried was entering 255 in the NoData value - however this removes the yellow background of the scanned map completely. Do you have an idea on how to fix this? Thanks

when this happens to me, i would set the "NoData Value" option to "0" with a single click of the up arrow next to it

black is 0, 0, 0 in rgb
