|These are not tutorials. Therefore, it is necessary to have a working knowledge of ImageMagick to reproduce the drawings. I do not even attempt to explain how or why. I do not teach how to use ImageMagick. (There are plenty of other resources for that.) I have simply recorded the parameters I used in producing these drawings.|
I sincerely do appreciate those of you who have asked my permission to use them, but it is not necessary. You do the drawing; it's yours. These are the coordinates I used; feel free to copy or alter them. Personal or commercial use? Collections? Go for it.
