I took a screenshot of an image in a VM window. The image is very clear. I want to use it in Find Image.
I am able to bring the VM window to the front, and I even have a step to click inside the VM, but I always get “Image not found” no matter what fuzz setting I use.
I would expect it to work, but I have occasionally seen cases where the screencapture system does not actually capture the entire image (some areas are black).
You can turn on debugging to see what image Keyboard Maestro is capturing and comparing with.
I should also mention, if the image you are matching is small or grey or both, then that is often very difficult for Keyboard Maestro to find. Confining your search to a smaller area on the screen (less than a quarter of the desktop area) will cause Keyboard Maestro to use a slower but more accurate search which can do a better job in some cases.
