Hello , maybe this can be useful ..I use the PrintKey2000 programm to take pics in room..It s very easy to handle and it s perfect to select small parts or define exacty what you need.
You just need to download it...it runs in stand alone...define a hotkey ( i choose f9 ) and then select what you want to get saved
It saves it directly on your computer..don t need to upload it in paint or gimp..etc..
Here is a link to download it from a german platform which i trust..( the app is in english ) but i m sure you can find it searching in google even on other platforms

Have fun
