What is a TGA file?
A TGA file is a file saved in the raster graphic format designed by Truevision. It supports 8, 16, 24, or 32 bits per pixel at a maximum of 24 bits for RGB colors and and 8-bit alpha channel. TGA files are often used to store texture files referenced by 3D video games.
In 1989, Truevision introduced new extensions to the Targa format to meet the needs of graphics professionals. Examples of the extra extensions include:
- Date and time the file was created
- Author name and comments
- Alpha channel type
- Pixel aspect ratio
- Gamma value
- A scaled-down postage stamp copy of the image (a "thumbnail" image)
