IMAQ image overlay export

[shuohuang]

Dear all:

I am having trouble with the IMAQ image overlay function. I have an image sequence with .tif format. I want to label a lot of tracking marks on the images. and the image overlay works beautifully. However, the original image is of .tif formate and it is I16 grey scale image. If I use merge overlay function and the whole picture will be horrible since it is converted to the RGB formate. 

So how can I save overlayed image as appeared in the window?

Thanks

Shuo

Use IMAQ Write Image And Vision Info File VI and store your 16 bit image to PNG with Vision Info instead of TIFF.

Note: the overlay stored inside of PNG in custom data - you will be able to open it only with IMAQ Read Image and Vision Info VI.

Thanks Andrey.

I just figured out an alternative way to do the job. I used some 3rd party software to convert my image to 32bit RGB, then perform the overlay and image output. The image now looks crystal clear and sharp. No issues anymore.

Thanks anyway Andrey.
