Attribute Functions
Use attribute functions to examine and change NI-IMAQ and camera attributes.
You can change some attributes while an acquisition is in progress. However, most attributes require that you call imgSessionConfigure to reconfigure the driver.
NI-IMAQ does not let you make any attribute changes that would have a detrimental effect on any acquisition in progress. If NI-IMAQ lets you change an attribute during a live acquisition, the effects are immediate. If NI-IMAQ does not let you change an attribute during a live acquisition, stop the acquisition, change the attribute, and restart the acquisition.
