I wanted to know what functions are working behind imaq? Are they visa functions? How can I view them on labview? Can visa be used as an alternate to imaq functions?
secondly how do i create dll files on labview 8.5?
IMAQ implements the latest image analysis algorithms. It's implemented by various methods. You won't be able to use VISA as an alternative.
In regards to creating a dll, this Community page will be helpful. https://decibel.ni.com/content/docs/DOC-15556
