Image export in the LabView Ring File

[parrot]

I am trying to modify this LL Ring Labview Example to acquire images for my LineScan cameras. I tried to export and save the images from buffer. I noticed that all the images were written to the computer hard disk when I stopped the LabView programm. I want to know if they were indeed live acquisition of the images, instead of repetition of last image. Is there any way to export images live when the specimen is running, instead of once when the programm is stopped.

Attached is the modified Ring example.

Thanks,

Helena

Hi parrot,

Thank you for using National Instruments forum.  I looked at your modified version of the LL Ring.vi.  Your current setup has you writing to the hard disk every time you run each loop iteration.  That means you are already doing exactly what it is you are asking for, writing to the disk every time you aquire an image.

Let me know if this is what you are asking for.

Thanks!

Thanks for your help, Justin.

I thought that the programm is doing that. But why the images are saved to the directory all at once. I was looking at the direcotry, the images are not saved until the program is stopped. Why is that?

Hi Helena,

The images are being written the whole time the program is running, but they might not show up in the directory until the program is finished.  One thing you could do to test this is to try to read some of the files after they have been writen.  You will be able to read from those files right after they have been writen, even if they aren't showing up in your directory.  I hope this helps.
