Délimiter image avec spline

[nicolas2]

Bonjour à tous, j'utilise ces routines pour présenter des plans de maisons (en vue de déposer des permis de construire. Ces LISP ne sont pas de moi).

 

[surligneur] Je fais une Spline en vue du détourage de mon image puis j'utilse cette routine.[/surligneur]
