A technique to capture large screenshots from http://gis.ktimanet.gr/

ktimatologio.js

/*
Instructions for Firefox:
	1. On Firefox, open http://gis.ktimanet.gr/wms/ktbasemap/default.aspx and zoom to your area of interest
	2. Hit Shift + F4 to open the Scratchpad and paste the code below, then click on “Run” (Ctrl + R).
	   You may close the Scratchpad. There’s no need to save anything.
	3. Input your desired image size on the prompt window (height equals width)
	4. Refine your position, eg: zoom with the scrollbar or pad by click and drag
	5. Capture a screenshot of the full page with Firefox’s built-in tools: https://screenshots.firefox.com/

Also works in Chrome but there’s no built-in way to capture the screenshot.
In Chrome, hit Ctrl + Shift + I and paste the code in the Console.
