Mathematica Import/Export Format

PXR (.pxr)

Pixar image format.
Raster image format.
Legacy format used in computer animation production systems and in medical imaging.
PXR is an acronym derived from Pixar.
Stores images as RGB or grayscale bitmaps at a resolution of 8 bits per channel.
Binary format.
Does not use compression.
Developed in 1986 by Pixar for the Pixar Image Computer workstation.

Import and Export fully support the PXR format.

IMPORT AND EXPORT

Import["file.pxr"] imports a PXR file, returning a graphics object.

Export["file.pxr", expr] exports graphics or any other expression as an image to a PXR file.

Import["file.pxr"] returns an expression of the form Graphics[Raster[data], opts], where data is an array of RGB color values.

Export["file.pxr", expr] creates a PXR image with the same image size as the displayed form of .

Because PXR is a raster image format, all fonts are rasterized on export.

Import["file.pxr", elem] imports the specified element from a PXR file.

Import["file.pxr", {elem, sub_a, sub_b, ...}] imports a subelement.

Import["file.pxr", {{elem₁, elem₂, ...}}] imports multiple elements.

The import format can be specified with Import["file", "PXR"] or Import["file", {"PXR", elem, ...}].

Export["file.pxr", expr, elem] creates a PXR file by treating expr as specifying element elem.

Export["file.pxr", {expr₁, expr₂, ...}, {{elem₁, elem₂, ...}}] treats each expr_i as specifying the corresponding elem_i.

Export["file.pxr", expr, opt₁->val₁, ...] exports expr with the specified option elements taken to have the specified values.

Export["file.pxr", {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 PXR 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
