Modifying Content in the Package - Adobe Acrobat and PDF for Architecture, Engineering, and Construction - page 99

In all cases, tags are generated automatically. Bookmarks are converted to links and placed at the start
of the file. When exporting images, Acrobat creates a subfolder named “images” to store the exported
image files. Images exported from a PDF file in this manner are numbered and use a prefix if specified in
the Settings dialog box.
Exporting a PDF File as Images
Instead of exporting a PDF file as a combination of text and images, you can export it as a single image per
page, which you might choose to use the content in another project or to create thumbnails to use in other
applications, such as visual links. If you want to protect the content of the document, exporting it as an
image with an attached security policy prevents manipulation of the content of the file.
To save a PDF file as images, choose File > Save As and select an image export option from the Save
As drop-down list. Click Settings to open the Settings dialog box and choose the options according to your
intended use. Acrobat will convert each page to an image the same size as the document page.
Exporting Images from a PDF File
Sometimes you may not have the source files available, but have images in a PDF file that you'd like to
reuse in another application. You can export the images from a PDF file - without the text - and specify the
minimum size for image extraction. The extraction process supports JPEG, PNG, TIFF, and JPEG2000
image formats. JPEG and JPEG2000 images having a specified compression and resolution aren't affected
by the settings you choose in the Settings dialog box.
Follow these steps to extract images:
1. Choose Advanced > Export All Images to open the Export All Images As dialog box. Locate and
select the folder you want to use to store the images.
2. Choose an image format from the drop-down list at the bottom of the dialog.
3. Click Settings to open the Export All Images As dialog box (Figure 8.15). Specify export settings
for the images; click the Extraction drop-down arrow and choose an image size for exclusion. The
default size is 1.00 inch, meaning images equal to or less than 1 inch are not exported. Excluding
images based on size is very useful if you are extracting images from a file containing a repeating
small image, such as a company logo.
4. Click OK to close the Settings dialog box, and then click Save to export the images to the specified
folder. The images are saved using the file's name and an incremental number.
Attaching Source Files to a PDF File
Source and ancillary information files can be attached to a PDF document, and viewed in Acrobat 6 or 7, as
well as Adobe Reader. Attaching additional files is a useful way of compiling files for a project, as well as
storing content in a single, easy-to-access location.
The simplest method for attaching a source file to a PDF file is by modifying the PDFMaker settings
before converting the file to PDF. In a program using a PDFMaker, choose Adobe PDF > Change
Conversion Settings to open the Acrobat PDFMaker dialog box and click Attach source file to Adobe PDF
in the Application Settings area of the Settings tab. Click OK to close the dialog box, and proceed with the
conversion.
