Targa Graphics (.vst)

The VST file extension, associated with Truevision Advanced Raster Graphics Adapter (TARGA), is a raster graphics file format developed by Truevision Inc. (now part of Avid Technology) in 1984. It was designed for high-color display support on IBM-compatible PCs and is commonly used for digital photos and textures. The format supports various color depths and includes an alpha channel for transparency. It remains popular in the video and animation industry due to its ability to handle large, high-quality images with minimal quality loss.

Continuous Acquisition and Life-cycle Support Type 1 Image (.cals)

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
