After changing the background correctly with the famous ctypes
import ctypes
ctypes.windll.user32.SystemParametersInfoW(SPI_SETDESKWALLPAPER, 0, fullpathofimage, 0)
the image was not fitting correctly in the screen, as Windows has 'Tile' as default wallpaper fit. Part of the image outgrew the screen.
¿Is there any way to change the wallpaper fit mode? (Center, Span, Fit, Stretch, etc) After changing the fit mode of the computer, each new change of wallpaper would respect the new fit mode. So it must be a system parameter, but i dont know where to edit.
In this answer, What are the Parameters for in: Python, ctypes.windll.user32.SystemParametersInfoA?, someone replyed with https://code.msdn.microsoft.com/windowsdesktop/cssetdesktopwallpaper-2107409c, but now its down and i can't find anything.
Thank you ind advance.
