Situation / Problem
Lets say, I want to create a document with workout or other sports instructions. There might be video-tutorials but I do not want to use stills nor photographs. Rather, the guide should contain sketches with detailed human body postures. Obivously only the position has to be recognizable; in best case: depictions of front, side. Publications and books - that I know of - usually don't contain such figures but only photographs.
Clarification / Example
By sketch I mean something in the style of these: 1, 2, 3, 4; not necessarly (would be nice to have though) as highly detailed as this. I do not refer to some symbols like here or there.
Question
How do I best create and insert such body posture sketches into my document ?
A solution should allow arbitrary postures and optimally yield vector-graphics.
Is there a way to do this with TikZ ? Or can you recommend a way to generate such vector graphics from pictures ?
