AUTOPAGE

AUTOPAGE is the image file used for the background of the full-screen automap. Heretic and Hexen both provide an AUTOPAGE lump in their respective IWADs to give the automap a parchment-like appearance; however, the lump can be used in any ZDoom-supported game. Any supported image format can be used at any scale. Images with larger/smaller dimensions than the user's screen resolution will be scaled up or down accordingly.

The MAPINFO map definition key MapBackground allows to specify a different AUTOPAGE lump name for a given map.

Displaying AUTOPAGE can be turned on or off with the "Draw map background" option, or with the am_drawmapback console variable.
