Re: c++ from labview?

Labview is slower. Additionally, c/c++ already is being used within the image acquisition process to decode the jpeg image received.

Do you know how much overhead is incurred when passing the image into the dll and back into labview?

I have had experience with c/c++; we're using labview because we think it's easier and development is faster. It looks like if the entire image acquisition process was handled by c++ code, fewer resources would be used since the image would be handed off only once. It would also be easier to use the mjpg method already implemented in c++, rather than rewriting that in labview (and finding/compiling a lib that has support for progressive jpg - unless I'm mistaken, the images in the mjpg stream are progressive and cannot be handled by the library function called by labview).

thx,
