I restarted designer again and now it is showing up. Thanks.

Not sure what model of camera you’re using, but since Firmware Version 5.6.0 Cognex has included web HMI functionality. I have started using this to show the operators why a vision inspection fails with the web browser module.

Ya, we have a mix of in-sight cameras and dataman readers. I’ve incorporated the web HMI to allow a live view and help with setup. However, I don’t believe live mode is available when the camera is online which is why I’m using Ignition to show a feed.

Application note for future visitors:

Cognex re-uses the image file name within the monitoring SVG file, which causes the Batik SVG canvas component to cache the image. This results in image/overlay mismatch. The solution is to use the component’s .flushImageCache() method each time you load the URI of the camera’s overlay SVG file.
