Thanks philippe!
It does work great in extracting the points from the path as I wanted.one thing i would like to know however, will it only abstract the M points and not the rest? since most path drawn by maps would have multiple joints of path in a single drawn path. thanks again! i'm trying it as i type =) --- In svg-developers@yahoogroups.com, Philippe Lhoste <[EMAIL PROTECTED]> wrote: > e2mieluv wrote: > > i do hope you guys could help me with this.
