MATHEMATICA IMPORT/EXPORT 格式

PDF (.pdf)

MIME type: application/pdf
Adobe Acrobat format.
Standard format for exchanging and archiving multi-page documents.
PDF is an acronym for Portable Document Format.
Binary file format.
Stores text, fonts, images, and 2D vector graphics in a device- and resolution-independent way.
Can also store embedded raster images.
Supports multiple lossy and lossless compression methods.

Import and Export support PDF Version 1.5 and earlier.

IMPORT 与 EXPORT

Import imports a PDF file, returning all pages as a list of graphics.

Export exports any expression to PDF.

Import["file.pdf"] converts the pages of a PDF file to Mathematica vector graphics.

Import["file.pdf", "Plaintext"] gives a plain text version of a PDF file.

Export["file.pdf", expr] creates a PDF file from an arbitrary expression, cell or notebook object.

Mathematica does not rasterize fonts or 2D vector graphics when exporting to PDF.

Import imports the specified element from a PDF file.

Import imports a subelement.

Import imports multiple elements.

The import format can be specified with Import or Import.

Export creates a PDF file by treating expr as specifying element elem.

Export treats each as specifying the corresponding .

Export exports expr with the specified option elements taken to have the specified values.

Export 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 PDF.

NOTEBOOK INTERFACE

In the notebook front end, Insert ► Picture and the Open menu allow import of a PDF file into a cell.

Save As exports the active notebook as a PDF file.

Save Selection As exports the selected part of a notebook to PDF.

参数

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:

	"Pages"	list of vector graphics, each representing a page of the PDF file
	"Plaintext"	textual content of the document, given as a string
	"Attachments"	list of attachments, imported as a Mathematica expression if possible
	"RawAttachments"	attachments given as a list of raw strings

Import by default uses the element.

On Export, attachments are given as a list of file path specifications or rules of the form "filename"-> expr, where is the name of the file attached to the PDF document, and expr is an arbitrary Mathematica expression. Objects that can be attached to PDF include Mathematica notebooks, cell expressions, text, image and graphics objects.

Importing individual pages:

	"Pages",n	vector graphics, representing the n page
	"Plaintext",n	textual content of the n page

Meta-information elements:

	"Author"	name of person who created this document
	"CreationDate"	creation date of the document, given as a DateList specification
	"Creator"	program that created this file
	"PageCount"	number of pages
	"Title"	document title

选项

Import options:

	"Password"	None	document password given as a string
	"TextOutlines"	True	whether to import characters as outlines

General Export options:

	ImageSize	Automatic	overall image size
	ImageResolution	72	image resolution for rasterization in dpi

Advanced Export option:

"AllowRasterization"

Automatic

whether to rasterize a graphic that requires advanced versions of PDF

Possible settings for :

	Automatic	automatically choose the most suitable rendering method
	True	rasterize a graphic that requires advanced versions of PDF
	False	use vector graphics
