Background

A background is a two-dimensional image
resource. It is one of two visual resources offered in Game
Maker, the other being
sprites. The main differences are that it can't
have animation, it can't be assigned to objects, but it can be used as a
tileset.

Specification

ENIGMA stores backgrounds as RGBA bitmaps. They can be stored in the
executable itself or be loaded externally on runtime.
LateralGM can load any Java-recognized image
format, such as bmp, jp[e]g, png, tif[f], and gif, as well as any
additional SPI-registered format such as wbmp and ico. In the end, the
format of the loaded file does not matter, as the storage mechanism is
the same. This may change as the project shifts to allow external
storage.

Uses

Backgrounds are usually used as scenery in the room.
Room can be populated with backgrounds via the room editor. Background
can also be split up into a tileset. They are small images that
correspond to a part of the background. Then they can be placed
individually in the room to form scenery. In a top down game these parts
could form a road for example.

They can also be drawn from an object's draw event.
