Page Content And Information
Show Large Images
Displays large images. If your system is slow to display image-intensive pages, deselect this option.
Use Smooth Zooming (Windows only)
When deselected, turns off animation effects, which improves performance.
Show Art, Trim, & Bleed Boxes
Displays any art, trim, or bleed boxes defined for a document.
Show Transparency Grid
Displays the grid behind transparent objects.
Use Logical Page Numbers
Enables the Number Pages command for matching the position of the page in the PDF to
the number printed on the page. A page number, followed by the page position in parentheses, appears in the Page
Navigation toolbar and in the Go To Page and Print dialog boxes. For example, i (1 of 1) if the printed number of the
first page is i. If this option is not selected, pages are numbered with arabic numbers starting at 1. Selecting this option
helps prevent unexpected behavior when clicking Back or Go Back in your web browser.
Always Show Document Page Size
Displays the page measurements beside the horizontal scroll bar.
Use Overprint Preview
Specifies whether Overprint Preview mode is on only for PDF/X files, never on, always on, or
set automatically. When set to Automatic, if a document contains overprints, then Overprint Preview mode is
activated. The Overprint Preview mode lets you see (on-screen) the effects of ink aliasing in the printed output. For
example, a printer or service provider could create an ink alias if a document contains two similar spot colors and only
one is required.
Reference XObjects View Mode
Show Reference XObject Targets
Specifies the type of documents in which reference XObjects can be viewed.
Location Of Referenced Files
(Optional) Specifies a location for the referenced documents.
Playing multimedia
Play multimedia
PDFs can include many types of multimedia files, including (but not limited to) Flash®, QuickTime, mp3, MPEG, and
Windows® Media files. You can play these files on a page or activate them from a link, bookmark, form field, or page
action. Each multimedia file includes a play area from which the media can be activated. The play area typically appears
on the PDF page as an image or a rectangle, but can also be invisible.
Any computer that has Adobe Reader® can play these files.
•
Media files created in Flash (FLV format)
•
Media files that comply with the H.264 standard for video compression
Media files in other formats require the necessary hardware and software to play.
To help protect your computer from viruses, Acrobat asks you if you want to play multimedia files from unverified
sources. You can change this default behavior in the Multimedia Trust preferences.
❖
Using the Hand tool or the Select tool, click the play area of the video or sound file. When the pointer is positioned
over the play area, it changes to the play mode icon
.
