Stardent AVS X-Image

Data type	Image
MIME type	image/x-avs
Primary use cases	Scientific visualization pipelines, raw/intermediate image interchange, streaming between applications

What is the AVS file format?

AVS is a legacy uncompressed raster image format (AVS X-Image) used mainly as an intermediate interchange in scientific visualization workflows.

AVS file characteristics

Data type	Image
MIME type	image/x-avs
Compression	Uncompressed
Color depth	8-bit per channel (32-bit ARGB/RGBA), supports alpha channel
Color space	RGBA (commonly treated as sRGB; no embedded profile)
Transparency support	Yes
Animation support	No
Resolution support	Width and height stored as 32-bit integers (practically limited by file size and tool support)
EXIF / Metadata support	No
Metadata	No standardized metadata
Typical file size	≈ 4 bytes/pixel + 8-byte header (e.g., 1024×768 ≈ 3.0 MB)

Advantages

The AVS file format offers several advantages that make it suitable for common use cases.

Very simple structure;
Fast read/write;
Supports alpha channel;
Convenient as an intermediate/streaming format

Limitations

The AVS file format has certain limitations that may affect its use in specific scenarios.

Uncompressed 32-bit pixels only;
No compression or animation;
Rare in modern workflows;
The same AVS X-Image may also appear with .x or .ximg extensions in some tools

Compatibility

AVS images are widely supported and can be viewed on most devices and platforms.

Supported platforms: Primarily desktop/workstation tools (e.g., Netpbm, Gnuplot, ImageMagick, XnView)
Supported devices: Computers/workstations
Browser support: No
Mobile support: No

Security considerations

As with any binary image format, malformed files can trigger decoder bugs; use trusted converters and keep them updated

AVS (Stardent AVS X-Image) is an extremely simple binary raster format: an 8-byte header stores image width and height (two 32-bit integers), followed by 32-bit pixels stored as alpha, red, green, blue bytes. It is mostly used for streaming or interchange between applications rather than for distribution.
