A python utility for screen capture from certain tiny devices.
The default device type is extracted from the executed script name. For example if you make a copy of the script and call it capture_tinysaultra.py, it will run with a default device type of tinysaultra.
The default device type can be overridden with the -d option.
It is convenient to have a copy of the script for each of the devices in use as one can just run the script (eg double click) without any switches.
For example: copy capture_.py capture_nanovnah4.py copy capture_.py capture_tinysaultra.py
Images are scaled, depending on the device type.
Two images are emitted, a 'normal' image and one with inverted colours which is more suited to printing (uses less toner, ink etc).
