Surfer can import and export AVS X-Image .X and .XIMG files.
The AVS X-Image format originated on UNIX workstations and is typically used to store true-color images containing an alpha channel, a feature that most other image file formats lacked at the time this file format was developed. An AVS X-Image file is a binary file containing a raster image with 8-bits each for the red, green, blue, and alpha channels (32 bits total per pixel).
