Aleph One Image File – file format by Bungie Studios

IMGA (Aleph One Image File) is a Bungie Studios proprietary format for storing images in the game Marathon 2: Durandal. It is a simple container format that stores a single 2D image, with optional metadata.

Aleph One Image File Format

An IMGA file is an image file format used by Bungie Studios’ games, including the Halo series, Destiny, and Marathon. The format stores 2D images in a compressed format, using a proprietary algorithm. IMGA files are typically used for storing textures, sprites, and other game assets.

The IMGA format is a lossy compression format, meaning that some data is lost when the image is compressed. However, the compression algorithm is designed to minimize the loss of detail, and the resulting images are typically of high quality. IMGA files are also relatively small in size, making them easy to store and transmit.

Using Halo

Halo, a first-person shooter game, commonly utilizes IMGA files. To open an IMGA file in Halo, follow these steps:

  1. Locate the IMGA file: Navigate to the folder where the IMGA file is saved on your computer.
  2. Start Halo: Launch the Halo game application.
  3. Open File Mapping: Within Halo, locate and click on the “File” menu option. Select “Open” from the drop-down menu.
  4. Select File Type: In the “Open” dialogue box, ensure that the “File Type” is set to “All Files (.)”.
  5. Find IMGA File: Locate the IMGA file from the file explorer window and select it.
  6. Open IMGA: Click on the “Open” button to import the IMGA file into Halo.

Using Other Software

IMGA files can also be opened using certain graphics editors or file viewers. Here are some options:

  1. GIMP: GIMP is a free and open-source image editor that supports IMGA files. Open GIMP and use the “Open” command from the “File” menu to select and open the IMGA file.
  2. Paint.NET: Paint.NET is another free and user-friendly image editing software that can handle IMGA files. Load the IMGA file into Paint.NET using the “Open” option from the “File” menu.
  3. Hex Editor: IMGA files can be opened and viewed in a hex editor as they are binary files. Use a hex editor such as HxD or 010 Editor to open and examine the internal structure of the IMGA file.

What is an IMGA File?

An IMGA file is a proprietary image format developed by Bungie Studios, primarily used in the first-person shooter game Marathon. IMGA files store bitmap images, typically game textures, such as character models, environmental textures, and weapon models. They contain compressed image data, employing a lossless run-length encoding (RLE) algorithm for efficient storage. IMGA files are typically large in size due to the high resolution and detail of the textures they contain.

Uses of IMGA Files

IMGA files are essential for the visual representation of Marathon. They provide the textures and graphics that make up the game’s environment, characters, and objects. By utilizing the lossless RLE compression, IMGA files retain the original image quality without sacrificing storage efficiency. This ensures that the textures remain visually appealing and maintain the intended aesthetic of the game. IMGA files are also used in other Bungie games, such as Halo: Combat Evolved, where they serve a similar purpose in defining the game’s visual appearance.
