Common card · No. 413234

Truevision TGA, often referred to as TARGA, is a raster graphics file format created by Truevision (now part of Avid Technology). It was the native format of TARGA and VISTA boards, which were the first graphic cards for IBM PC compatibles to support high color or true color display. This family of graphic cards was intended for professional computer image synthesis; the usual resolutions of TGA image files match those of the NTSC and PAL video formats.
