USING ACROBAT 9 STANDARD 126 Saving and exporting PDFs Use Mapping Table Default uses the default character encoding defined in mapping tables, which appear in the Plugins/SaveAsXML/MappingTables folder. These mapping tables specify many characteristics of how the data is output, including the following default character encodings: UTF-8 (Save as XML or HTML 4.0.1) and HTML/ASCII (Save as HTML 3.2). Generate Bookmarks Generates bookmark links to content for HTML or XML documents. Links are placed at the beginning of the resulting HTML or XML document. Generate Tags For Untagged Files Generates tags for files that are not already tagged, such as PDFs created using Acrobat 4.0 or earlier. If this option is not selected, untagged files are not converted. Note: Tags are applied only as part of the conversion process and are discarded after the conversion. This is not a method for creating tagged PDFs from legacy files. Generate Images Controls how images are converted. Converted image files are referenced from within XML and HTML documents. Use Sub-Folder Specifies the folder in which to store generated images. The default is Images. Use Prefix Specifies the prefix added to the image file names if you have several versions of the same image file. File names assigned to images have the format filename_img_#. Output Format Specifies the final format. The default is JPG. Downsample To Downsamples image files to the specified resolution. If you do not select this option, image files have the same resolution as in the source file. Image files are never upsampled. JPEG and JPEG 2000 options If your PDF contains a collection of images, you can export them individually as JPEG, PNG, or TIFF files by choosing Advanced > Document Processing > Export All Images. Note that the options available depend on whether you are exporting a document to JPEG or JPEG 2000. Grayscale/Color Specifies a compression setting that balances file size with image quality. The smaller the file, the lesser the image quality. Tile Size Divides the image being compressed into tiles of the given size. (If the image height or width is not an even multiple of the tile size, partial tiles are used on the edges.) Image data for each tile is individually compressed and can be individually decompressed. The default value of 256 is recommended. This option is available only for JPEG 2000 format. Format Determines how the file is displayed. Available only for JPEG format. • Baseline (Standard) Displays the image when it has fully downloaded. This JPEG format is recognizable to most web browsers. • Baseline (Optimized) Optimizes color quality of the image and produces smaller file sizes but is not supported by all web browsers. • Progressive (3 scans-5 scans) Downloads the image first as a low-resolution image, with incremental quality improvements as downloading continues. RGB/CMYK/Grayscale Specifies the type of color management to be applied to the output file and whether to embed an ICC profile. Note: If you use the Save As or Export All Images command on a PDF that contains JPEG and JPEG 2000 images, and export the content to JPEG or JPEG 2000 format, the resulting image may look different when opened in Acrobat. This can happen if the images have a color profile included at the page level but not inside the image data. In this case, Acrobat cannot bring the page-level color profile into the resulting saved image. Last updated 9/30/2011
