The TGA (Truevision Graphics Adapter) image format, also known as TARGA, is a raster graphics file format commonly used for storing images, especially in the early days of computer graphics. TGA files support a variety of color depths, including 8-bit, 16-bit, 24-bit, and 32-bit, as well as alpha channels for transparency. TGA is well-suited for applications in the gaming and video industry due to its ability to handle complex images with high color fidelity. The format is recognized by the .tga or .targa file extension and remains relevant for certain niche applications, although it has become less common with the advent of more modern image formats.
