Well, that was very interesting! Doing as you suggested does not solve the problem. If you use a sensible sized pen (fairly small), nothing visible happens, and the 'halo' looks just as before, though there is a suggestion of it disappearing at the points where the drawn circle overlaps the edges of the original image (the top, bottom, and two sides). If you use a thicker pen, it is more obvious that the 'halo' is gone at the overlapped edges, but it is just pushed out to the edge of the drawn circle over the rest of the rendered image - it still always appears where a 'transparent' pixel was adjacent to one of another color, whether that pixel was part of the original bitmap or subsequently drawn on the Graphic. Presumably, therefore, it is an artefact of the [Bitmap].MakeTransparent() Function, but I have no idea why it has not (as far as I can tell) been described before
Parenthetically, I now see that that function forces the Bitmap on which it is invoked to 32bppRgb mode, since that format has the alpha channel which it needs, so any attempt to use a different format would be pointless.
