Saving a frame img to file

Is there any “simple” way to save an img frame (tipically from video or webcam source)?
I have to save A LOT of different frame from different video, to create a collection of img to use later (probably).

tnx :slight_smile:

Seems that i’ve found what I was looking for just in the of package :stuck_out_tongue:

ofImage im;;  

Tnx anyway.
