The Targa format, which stands for Truevision Advanced Raster Graphics Adapter, was designed by Truevision (now Avid Technology) in 1984 for use with its first video software programs. The original format consisted of 2 areas:

TGA File Header
Image/Color Map Data

While these two sections were included in the original 1984 specification of the Targa format, "Developer Area," "Extension Area," and "TGA File Footer" sections were added in 1989. This specification is known as the "New TGA Format" and consists of the following 5 areas:

TGA File Header
Image/ColorMap Data
Developer Area
Extension Area
TGA File Footer

Besides the three new sections of the image format, Truevision also introduced several new extensions to the Targa format in 1989 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)
