[chimerax-users] Export silhouettes as SVG?

[Aaron Lewis]

As a workaround, you might try saving a bitmap image of the edges detected
by Chimera (e.g. set bgColor white; color #1 white; lighting flat
ambientIntensity 2; save ~/lines.png), then convert that to a vector
graphic by thresholding or Canny detection in a program like Inkscape. This
seems to give sensible paths, even for complicated outlines.
