Hello All;
I am designing an application that is currently using IMAQ Image Display control to view large images (5K x 3K and larger). My problem is that these images take 10-20 seconds to load and display, whereas if I use IMAQ WindDraw to display my image in a separate window, it only takes a couple of seconds. My application is designed such that I am making use of the Subpanels in LabVIEW 8.0, and to make it pleasant for the user, the interface is such that my line profile, histograph and image viewer displays are contained within the same GUI (panel).
I read the National Instruments application note regarding displaying of large images, and it did not seem to make a difference. For example, I switched the 'modern' IMAQ Image Display control with the classic Image Display control, since the 'classic' does not contain any of the 3D rendering tools which might slow the process down.
Why is there such a huge difference in loading times if I am trying to do exactly the same thing with both methods? How can I bring the IMAQ Image Display control up to the same speed as the IMAQ WindDraw tool?
I am currently using LabVIEW 8.0 with the latest IMAQ/NI Vision package from NI (IMAQ v7.1?). Thanks.
DJH
