Can the program proposed by Alexei Boulbitch at the post of Custom arrow shaft be adapted to retouch an image in setting a mask arround the part one desires to disapear? This is only a suggestion, there may be a more straightforward way to do it.
In the famous following picture
Nicolas Yehzov has been edited out. The original picture was the following
I was wondering if It could be done in Mathematica, in the same way one can extract a part of an image. The reason for which I refer to the Custom arrow shaft post is that I think the mechanism must be similar.

Sorry not to have been enough precise. Here is how i can operate under LaTeX + PsTricks
I can construct a mask by hand, point to point --- which is particularly borying --- and erase one of the mass killers. It's there that I was thinking of Alexei's Code. After that either I can mask the part under the clipping path or I can add negatively for the rest of the image. The whith the help of the various graphic commands I can reconstruct the missing part. For instance it should not been too difficult to rebuild the wall and the water.
Perhaps with today technology can we do a better job than the one of the past where you see the effect of pencil drawing. Of course, here is not my intension but I give always to my students some pictures to anchor them in reality.
In all the case I am particularly gratefull to all your answer even if the questions are not always clear. I am particularly impress by your skills and by this incredible tool I have had for nearly 30 years without realizing how it could be such a great tool.
