Application Visualization System X Image (.x)

The X file extension is linked to the Application Visualization System (AVS), a high-end format designed for storing true-color images with transparency. This format stands out for its alpha channel capability, which was a unique feature at its inception, allowing for transparent image representation. AVS X Image files are binary and hold raster graphics, allocating 8 bits per channel for red, green, and blue, with alpha summing up to 32 bits per pixel. This depth supports over 16.7 million colors with transparency, offering a powerful solution for superior imaging requirements.

Initially developed for UNIX systems, the AVS X Image format is widely adopted in sectors needing intricate and accurate imaging, such as scientific visualization. Its alpha channel is essential for constructing layered composite visuals with variable transparency levels. Despite newer formats, AVS X Image's uncompressed format remains significant, preserving image integrity without compression-related degradation.
