I just discovered that gocr works a lot better than tesseract at recognizing text in a Virtualbox screen capture. If you're running a Virtualbox virtual machine, there's a command to take a screen cap. That generates a png file. You can run gocr on that to see what the screen on the virtual machine says. Something like this in linux: vboxmanage controlvm $VMNAME screenshotpng /tmp/screencap.png gocr /tmp/screencap.png -- John G. Heim; jheim@math.wisc.edu; 608-263-4189
