How to save acquired images

[navman74]

Hello,

It still isn't working this time 'Error 1 occurred at Check Data Size.vi'. Can you take a look at the attached VI?

Thanks

Sometimes it "helps" to read the Help messages.  Create File with Incrementing Suffix is designed for creating "normal" LabVIEW Files -- it actually opens the file for reading or writing as a member of the File I/O functions.  The Image functions play by different rules -- the IMAQ Write combines File Opening with File Writing, and doesn't use the File Reference.

So you have to be clever.  [Note -- I haven't actually tested this, but I'm willing to bet a dime, or a beer during NI Week's Block Diagram Party, that this will work ...].

Take the File Name that you want to use, pass it through Create File with Incrementing Suffix, and immediately close the File Reference.  Now take the "Actual Path" (the second output) from Create File with Incrementing Suffix, which is a Path, and should have an "incrementing suffix", and use that as the input to Write PNG File.
