[pstricks] new member, new question

[Marcos-Arenal, JL]

Hi everyone;
As a brand new newbee, mine is a probably basic question.
 
I have several images like the ones I attach that I would need to re-draw in order to improve the image quality.
 
Anyone in the forum has any suggestion to do this in the most time-efficient way?
Is PSTrick the way to go?
how do I get started?
 
[I told you:    in the eternal words of Sir David Bowie: I am an absolute beginner......]
thank you very much
 
JL
