[PD] Re: PD-list Digest, Vol 19, Issue 84

[Ramirez Hugo Francisco]

Dear PDpers.
Do you think is possible to connect or use a C programm as a external with
our beloved Pure Data??
Meaning is it possible to use for instance a [pix_video] or something else] and
then use my own C program to make image processing??
Good Vibes
Hugo
