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 and Export fully support the MGF format.

IMPORT AND EXPORT

Import["file.mgf"] imports an MGF file and returns an image.

Export["file.mgf", expr] exports an image, graphics or any other expression as an MGF raster image.

When exporting Mathematica graphics or arbitrary expressions to MGF, the resulting image has the same raster size as its displayed form.

Image objects are by default exported at their raster size.

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, sub_a, sub_b, ...}] 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 expr_i as specifying the corresponding elem_i.

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.

ImportString and ExportString support the MGF format.

ELEMENTS

General Import elements:

	"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:

	"Cell"	notebook Cell expression representing the image
	"Graphics"	raster image given as a Graphics object
	"Image"	image object

Import and Export by default use the "Image"element for MGF files.

OPTIONS
