ADOBE ACROBAT 3D VERSION 8

User Guide

Page Description Includes general information about objects on a PDF page, such as the type of object (for example,

whether it is an image, a piece of text, or a smooth shade) or whether it is inside or outside the viewable area of the

page, or how far it is from the trim box.

OPI Includes properties for analyzing all existing OPI links (comments), whether from OPI version 1.3 or 2.0. The

possible OPI entries in a PDF are the same as in PostScript files.

Embedded PostScript Refers to thePostScriptcodethatcanbeembeddedintothe PDF.Thereare threeproperties:

one for a PostScript operator used directly in a page description; one for PostScript code embedded in a PostScript

XObject; and one for an early form of a PostScript XObject, a PostScript Form XObject.

Object Metadata Includes information embedded with the object, such as its creator, resolution, color space,

document, and the document is converted to PDF, this information can be retrieved and checked by properties in

this group.

Annotations Includes most characteristics of comments and drawing markups, traps, and printer marks.

Form Fields Includes properties for form fields.

Layers Checks for optional content, which may affect the appearance of a page.

Pages Includes page numbers and page sizes that represent the various document boxes supported by Adobe PDF

1.3 and later technology (media box, bleed box, trim box, and art box). This group also includes plate names for PDF

pages that belong to a preseparated PDF.

Document Includes all the pieces of information that apply to the PDF as a whole, such as whether the document is

encrypted, contains form fields, or contains bookmarks.

Document Info ListsallthestandardentriesthatcanalsobeaccessedbytheDocumentInfodialogboxin Acrobat,

and information that has been standardized by the ISO 15930 standard (PDF/X).

Document Metadata Includesinformationembeddedwithinthe document,suchasitstitle, author,copyright,and

keywords applied to it. This information is also available in the Document Metadata section of the Document

Properties dialog box in Acrobat. (Choose File > Properties, click the Description tab, and then click Additional

Metadata.)

Structured PDF Includes several basic properties for the tagging structure in a tagged PDF, for which the PDF/A

standard defines constraints.

Output Intents For PDF/X Or PDF/A Defines which output process the PDF has been prepared for. A PDF intended

for high-resolution printed output typically contains an output intent with an embedded ICC profile, for use by a

proofing device or a device’s RIP (raster image processor).

Output Intent For PDF/X Or PDF/A (ICC Profile Properties) Includes properties for accessing information from an

ICC profile embedded in the output intent. This group includes the same properties as ICC profiles for objects, such

as profilenameand type.The ICCprofile describesthe output conditionofthe device wherethedocument willbe

imaged.

Efficiency Of PDF Content Stream Helps determine how efficiently page descriptions are encoded. For example, it is

possible to include the text Hello as a text operator for the whole word, or as several text operators for each character

in the word. The latter is less efficient and reduces the speed of page rendering. The efficiency checks return

percentages for several types of operators. A smaller value in most cases is better than a higher value.

Errors In PDF Syntax Returns information about specific errors in a PDF’s syntax. For example, if certain keys

requiredbythePDF specificationare notincluded, Acrobatmaystillbeabletorenderthefile.ForpredictablePDF

rendering, however, it is preferable to encode all PDFs in strict compliance with the PDF specification.
