Hi,
You can do this 2 way. When you are doing the georeferencing, you can select
"use 0 for transparency when needed." This can sometimes give good results but
can leave some transparent pixels in the map depending on the image.
Another way is to right click on the layer in the layer
I'll pass this to them to give a try. Thanks!

What about setting the "black areas" to Nodata? (or even converting
the black to real nodata values)
Properties -> Transparency -> No data value : Insert the black value here ..
Or use the rastercalculator to get rid of the black

Hello, QGIS gurus and friends.
Some of my students are georeferencing historical maps in QGIS, and want to
remove the black edge areas that appear after the raster arrays are warped, or
at least make these and only these black areas completely transparent. Seems a
simple task? Thanks- Scott
