Stitching images with overlays

[falkpl]

I am stitching one large imaq image from several smaller images using image to image copy.  The small images each have several overlays.  After the image to image copy the overlays from the small images are lost. How can this be avoided.  Or at least how can I get the overlay image information to manipulate it and reapply the data.

Is this possible, it seems that it should be.

The image overlay data is lost when performing the image to image copy because you lose the origin (0,0) of the small image, to which all overlays are relative.

You are going to need to user the IMAQ set overlay properties VI to configure the behaviors of the overlays before you copy them.

An easier method would be to merge the overlay with the picture before copy, but you would lose pixel data under the overlay, and the image would convert to RGB.

I was hoping I missed something,  I am supprised that there is no easy way to get overlay data back off of an image space.

I will

have to pass the locations of the overlays as metadata,
