Aleph One is an open-source game engine that runs Marathon 2: Durandal and related Marathon content. An IMGA file contains image data used by the engine while the game is running.
The file is part of the game's resource data and is loaded by Aleph One together with other files required by the game or scenario. It is not normally opened or edited separately.
The Aleph One engine is available for Microsoft Windows and other platforms. The IMGA format remains relevant to Aleph One game data, but it is a specialized resource format rather than a general-purpose image format.
Open an IMGA file with the Microsoft Windows version of Aleph One. Place the file in the appropriate game or scenario data folder so that the engine can load it.
Do not expect an image editor to display it directly; the file is intended to be read as part of Aleph One game data.
IMGA files are specialized Aleph One game resources and do not have a practical general-purpose image conversion workflow. Aleph One uses the file in its native form.
