TGA, also known as the Truevision Graphics Adapter format, is a raster graphics file format created by Truevision Inc. in 1984. It is primarily used in the video game industry and computer animation for storing texture maps and sprites due to its support for alpha channels. While largely considered a legacy format superseded by PNG, it remains relevant in specialized 3D modeling workflows and is inherently safe as it lacks script support.
