webcam snapshot python

Hi, 

This was working the other day, but now it is not which makes me suspicious of the code. 

I am using firefly's webcam as an input and python to create a .bmp snapshot. 

I am only doing this because Firefly does not offer a way to send a boolean value to their 'snapshot' component to create an automated snapshot. Thus I send a boolean from python to the 'snapshot' component and it should work...

here is the code and attached definition. Thank you in advance. 

if Capture == True:
#extract an image
image = bmp.CopyPixelsTo(image)

#output image
snapshot = image

    Hi johnnyUtah05,

    maybe you could use a "Data Dam" (it's a special param), that way nothing will flow downstream and the FireFly component will not run until necessary?

      Hi Erik,
      you could use the Firefly SnapshotSequense component by setting the number of snapshots to record (input N) to 1. (Note: this will leave a "_0" suffix on the filenames).

      Only thing is that you'll have to come up with a way to name the files sequentially.
