USING ACROBAT X PRO 325 Editing PDFs Clean Up panel The options in the Clean Up panel of the PDF Optimizer remove useless items from the document. These items include elements that are obsolete or unnecessary for your intended use of the document. Removing certain elements can seriously affect the functionality of the PDF. By default, only elements that do not affect functionality are selected. If you are unsure of the implications of removing other options, use the default selections. Object Compression Options Specifies how to apply Flate compression in the file. Use Flate To Encode Streams That Are Not Encoded Applies Flate compression to all streams that aren't encoded. In Streams That Use LZW Encoding, Use Flate Instead Applies Flate compression to all content streams and images that use LZW encoding. Discard Invalid Bookmarks Removes bookmarks that point to pages in the document that have been deleted. Discard Invalid Links Removes links that jump to invalid destinations. Discard Unreferenced Named Destinations Removes named destinations that are not being referenced internally from within the PDF document. Because this option does not check for links from other PDF files or websites, it does not fit in some workflows. Optimize Page Content Converts all end-of-line characters to space characters, which improves Flate compression. Optimize The PDF For Fast Web View Restructures a PDF document for page-at-a-time downloading (byte-serving) from web servers. Text and objects Choosing a tool A common misconception about PDF documents is that they should behave like any other document that contains images and text, letting you freely move or edit items on a page. A PDF is like a snapshot of your original document. You can perform minor touch-ups, but if your PDF requires substantial revision, it's easier to make changes to the source document and regenerate the PDF. For editing text and objects, choose from the tools in the Tools task pane. To insert editing marks in a PDF to indicate your changes to the original document, see "Mark up text with edits" on page 155. The Edit Document Text tool lets you add to and replace existing text if the fonts used are available on the system. If the fonts aren't available, you can change only the appearance of existing text. However, you can add new blocks of text using the Edit Document Text tool. To wrap text on a line during editing, select Enable Text Word Wrapping in the Touchup Preferences. Add or Edit Text Box command also lets you create new text, but provides fewer options to modify new text than the Edit Document Text tool. See video The Basics of Editing a PDF Document for a quick overview. Note: Using Edit Document Text may affect how the document reflows, which can make the document less accessible to the visually impaired. The Select Object tool provides basic editing capabilities for most objects. You can modify the size, page location, and properties of images, links, fields, and multimedia objects. You can make these same changes with the tool used to create the object. To scale, rotate, flip, or clip an image or object (including text blocks), use the Edit Object tool. The Edit Object tool can also place images and change an object's color space. If you need to edit the source file for an embedded image or object, the Edit Object tool can start an image-editing or object-editing application. Last updated 10/11/2011
