TGA (Truevision TGA) is a raster graphics file format that was one of the first to support truecolor (24-bit) images. Known for its simplicity and ease of implementation, TGA is still widely used in the video game and animation industries for storing texture maps and sprites. It supports alpha channels and simple RLE compression. Sample TGA files are used to test graphics engines and game development tools. Developers use them to verify the correct loading of textures and alpha transparency. They are also used to test legacy support in image viewers and to benchmark the performance of uncompressed image loading.
