Mathematica Import/Export Format

TGA (.tga)

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 and Export fully support Version 2.0 of the TGA format.
  • Import["file.tga"] imports a TGA file, returning a graphics object.
  • Export["file.tga", expr] exports graphics or any other expression as an image to TGA.
  • Import["file.tga"] returns an expression of the form Graphics[Raster[data], opts], where data is an array of RGB color values.
  • Export["file.tga", expr] creates a TGA image with the same image size as the displayed form of expr.
  • Because TGA is a raster image format, all fonts are rasterized on export.
  • Import["file.tga", elem] imports the specified element from TGA.
  • Import["file.tga", {elem, suba, subb, ...}] imports a subelement.
  • Import["file.tga", {{elem1, elem2, ...}}] imports multiple elements.
  • The import format can be specified with Import["file", "TGA"] or Import["file", {"TGA", elem, ...}].
  • Export["file.tga", expr, elem] creates a TGA file by treating expr as specifying element elem.
  • Export["file.tga", {expr1, expr2, ...}, {{elem1, elem2, ...}}] treats each expri as specifying the corresponding elemi.
  • Export["file.tga", expr, opt1->val1, ...] exports expr with the specified option elements taken to have the specified values.
  • Export["file.tga", {elem1->expr1, elem2->expr2, ...}, "Rules"] uses rules to specify the elements to be exported.
  • See the reference pages for full general information on Import and Export.
"Elements" list of elements and options available in this file
"Rules"full list of rules for each element and option
"Options"list of rules for options, properties, and settings
  • Data representation elements:
"Data"array of color values
"Graphics"Graphics object representing an image
"GrayLevels"array of normalized gray-level values
"RGBColorArray"array of RGBColor objects
  • Import and Export by default use the "Graphics" element for TGA files.
"BitDepth"bits used to represent each color channel in the file
"ColorSpace"color encoding used in the file
"ImageSize"raster dimensions
  • General option:
ImageSizeAutomaticoverall image size
