can not use IMAQ ImageToArray and IMAQ Rotate on CVS

[Richard Zhu]

when using my image processing DLL, I have to use IMAQ ImageToArray and
ArrayToImage which call the NIVissvc.dll and NIVision.dll . these are very
common IMAQ fuctions, in Labview, all my vi works well, when this exe
running on the CVS, it says can not find (or load) the ImageToArray, we can
use many IMAQ functions like imageExtract, IMaqCreate, on CVS before, but
failed on this one and the IMAQ rotate as well, we checked the dll on CVS
RT/System dir, the NIVision.dll is 2MB, and the one on my PC win/system32 is
2.2MB, then we copy the 2.2MB DLL to CVS , then the CVS says canot find the
NIVision.dll, is the DLL on pc not for real time ? what the diff btw DLL on
CVS and on LV in PC ?

don't how to use some sim
ple IMAQ functions on CVS like IMAQ Rotate and
ImageToArray etc, or the DLL version on my CVS is not a full version ?

Richard,

I am not sure why you might be running into this problem. The Image to Array, Array to Image, and Rotate VIs should all work just fine on the Compact Vision System (CVS). In fact, as I am writing this post, there is a CVS on my desk that is using all of those functions.

If you are having trouble getting this to work, I would suggest that you verify that you have both NI-IMAQ for IEEE 1394 RT and IMAQ Vision RT installed on the CVS. You would need to have both of these installed to have this work properly.

As for the DLLs that you mentioned, I would not suggest copying the DLL from your PC to your CVS, as they have different operating systems, and any system specific functionality would not work. Finally, since you have already made modificati
ons to your CVS's software, you may want to delete all the software off the CVS and try a new installation of the software just to be sure that it is installed correctly.
