TGA (.tga)

Background & Context

    • Common MIME types: application/tga, image/tga, image/tga
    • Truevision TARGA format.
    • Raster image file format.
    • Widely used in animation and video applications.
    • Was native format of TARGA video cards.
    • Binary format.
    • Supports color-mapped and true-color raster images.
    • Can compress data using a run-length encoding method.
    • Supports alpha channels.
    • Introduced by Truevision in 1984, updated as Version 2.0 in 1989.

Import & Export

  • Import["file.tga"] imports a TGA file and returns an image.
  • Import["file.tga",elem] imports the specified element from TGA.
  • The import format can be specified with Import["file","TGA"] or Import["file",{"TGA",elem,…}].
  • Export["file.tga",expr] exports an image, graphics, or any other expression as a raster image to TGA.
  • When exporting Wolfram Language graphics or arbitrary expressions to TGA, the resulting image has the same raster size as its displayed form.
  • Image objects are by default exported at their raster size.
  • Because TGA is a raster image format, all fonts are rasterized on export.
  • See the following reference pages for full general information:
  • Import, Exportimport from or export to a file
    CloudImport, CloudExportimport from or export to a cloud object
    ImportString, ExportStringimport from or export to a string
    ImportByteArray, ExportByteArrayimport from or export to a byte array
