Saving one frame at a time?

Question

Cheers!
I am using Low-level Grab Raw Data.vi example from NI-IMAQ. I want to save one frame at a time and then set the file position to end (and maybe add some mark that I recognize where the next frame begins). I know that it copies the raw data of the specified frame into Image Data Array. But does it write (in this example) data of one frame to disk and then set file position to end? If not, how to modify it?
How does changing number of buffer affect? I mean if I increase it >1 does it affect to number of frames to write per one iteration time of while loop?
I have Pixelink PL-B741F-BL camera. http://www.pixelink.com/products_info.asp?productc​ode=PL-B741F-BL&f-category=CMOS%20Imaging%20Module​...
Kudos for good help!

LH,
You may (you can see Groups in the Layers palette with the layer expanded):
1) Ctrl/Cmd+A to select everything and Ctrl/Cmd+Shift+G to Ungroup ;
2) ShiftClick the circle to deselect it; if it is still a Group (all of its own), Ungroup again;
3) With the Centre Reference Point ticked in the Transform palette multiply the W or H value by 1.1 (just add *1.1 in the box) and Ctrl/CmdEnter to keep proportions (this is to make sure that they are long enough);
4) Ctrl/Cmd+A to select everything again and Pathfinder>Divide (this will make pie pieces);
5) Drag over the centre with the Direct Selection Tool and press Delete (this will rid you of the inner parts of the pie pieces so you just have the outer rim in pieces).
This should give you the 30 independent curved lines forming the circle, two of them with an extra (original) Anchor Point.
