16bit to 8bit image conversion vb

[tres0422]

I am trying to save an image as a jpeg.  To do this I need to make the image 8bit.  This is one line in the sub to convert the image.  I get a "Runtime error 5.   Invalid Index"  How can I overcome this.  Is there a better way to do it?

CWIMAQVision1.Subtract Image, HistogramReport.Item(0).PixelRange.Min, Image

Although not Visual Basic (although there are references to it), I posted a similar question earlier. See the thread on "C and LUT", http://forums.ni.com/ni/board/message?board.id=200&message.id=8720

Whoops, sorry, dunno how to delete that above msg. Ignore it - it's not really relevant...

tres0422,

Was this problem fixed by the solution in your other thread?

Ryan,

   Yes sir and thanks for following up on this thread.  Should I post the code for future users?  I will admit I am an amature so my code is not the  most efficient but it got the job done this time.  Thanks again for your help.

Thanks,

     Thomas

No problem.  The code is probably unnecessary in this thread.  For my edification however,  I would be interested if you would post the final working code in the other thread.

Thanks,

Ryan F.
