LabVIEW 8 Save JPEG Error (blank/gray screen)

[rCassani]

I have the some problem as elkapitann, I'm using the method "Get image" on a XYGraph, the method is called every 120seconds, then the image  caught is saved as .jpg file. Some of the images saved are showed gray, that error is random. I think it´s problem of RAM, but I've 752MB.  I'm using Windows XP. When the application runs for more than 6 hours, the problem is more frecuently. I'm using LabVIEW 8.2.1.
Thanks

Hi Ray,

Have you followed Devin's suggestions from the earlier post?  This is a known issue for us, and R&D is still currently working on it.  He has provided a workaround for this issue that may be able to resolve the issue for the time being. 

Please let me know if you have additional questions.

Hello ,
I am trying to save images from a USB camera into a file using Labview. I can see the images on Labview but I can't save them. How do I proceed?

Hi Mike,

I am not exactly sure of what you are trying to do, but if you are have image data in the correct format in LabVIEW, you should be able to wire this into a Write JPEG File, Write PNG File or Write BMP File vi, which can be found if you right-click on the block diagram and go to Functions>>Programming>>Graphics & Sound>>Graphics Formats.

If this is not what you need, please provide more information on what data type you are working with, what file type you want to save the images as, and more details about what you are programming.

Also, in the future, it will be easier to track and answer your questions if you post your them as new issues instead of at the end of other separate posts.

Thanks,

Stephen S.
