Hi, I am using AVT camera Pike with Laview vision 2012
When I use Example code 'Grab and Attributes Setup.vi' (<NI supported Example),
I simply add the event case for overlay function (such as 'IMAQ Overlay Oval') with Image by Local Variables connection (image input - output).
Event case:
Image------[IMAQ Overlay Oval]--------Image
Rectangle Control ---|
IMAQ Overlay should keep the overlay on buffer memory if I input the rectangle value.
Problem is that the overlay disappeared if I use 8 bit image format?.
but at the 16bit image format, the image keep the overlay image (colored overlay).
It seems the overlay buffer is removed by acquiring new 8 bit image, but 16 bit format, the overlay is still alive.
Is it bug or what am I wrong?
