Mathematica Import/Export Format

MGF (.mgf)

Wolfram Mathematica MGF bitmap format.
Used by the Mathematica user interface for storing raster images.
MGF is an acronym for Mathematica Graphics Format.
Binary format.
Stores a single image as an RGB raster at a resolution of 8 bits per color channel.
  • Import["file.mgf"] imports an MGF file, returning a graphics object.
  • Export["file.mgf", expr] exports graphics or any other expression as an MGF raster image.
  • Import["file.mgf"] returns an expression of the form Graphics[Raster[data], opts], where data is an array of color values.
  • Export["file.mgf", expr] creates an MGF image with the same image size as the displayed form of expr.
  • Because MGF is a raster image format, all fonts are rasterized on export.
  • Import["file.mgf", elem] imports the specified element from an MGF file.
  • Import["file.mgf", {elem, suba, subb, ...}] imports a subelement.
  • Import["file.mgf", {{elem1, elem2, ...}}] imports multiple elements.
  • The import format can be specified with Import["file", "MGF"] or Import["file", {"MGF", elem, ...}].
  • Export["file.mgf", expr, elem] creates an MGF file by treating expr as specifying element elem.
  • Export["file.mgf", {expr1, expr2, ...}, {{elem1, elem2, ...}}] treats each expri as specifying the corresponding elemi.
  • Export["file.mgf", expr, opt1->val1, ...] exports expr with the specified option elements taken to have the specified values.
  • Export["file.mgf", {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.

  • Data representation elements:
"Cell"notebook Cell expression representing the image
"Graphics"raster image given as a Graphics object
  • Import and Export by default use the "Graphics"element for MGF files.
