Adobe Pro – Steps Involved in This Project

Steps Involved in This Project

Susan can work entirely from within Acrobat’s Picture Tasks plug-in to create the presentation as well as different print versions of her images. She can also e-mail the presentation right from Acrobat.

First, she plans to import the images into Acrobat in a binder, or combined PDF document. After using the Picture Tasks’ features, she’ll have a slideshow complete with a title, slide transitions, and music.

To create her slideshow, Susan needs to

  1. Import the group of images into Acrobat, where they are converted to PDF
  2. Open the Picture Tasks’ Export to Slideshow dialog and configure the slide-show’s contents, adding a title, transitions, and music
  3. E-mail the slideshow PDF to her client

You can work with a range of image formats in Acrobat. Susan is working with JPEG images, so we’ll focus our discussion on that format.

Working With Other Image Formats

If the images are not in JPEG format, or if Susan wants to use more transition options, include additional text, or control the compression of the images in the slideshow manually, she can create the slideshow in Acrobat without the benefit of the Picture Tasks plug-in. This is what she needs to do:

  • Add transitions to create a slideshow in Acrobat. For more on transitions, see Chapter 2.
  • Add captions using the TouchUp Text tool. For more on the TouchUp Text tool, see Chapter 9 and Bonus Chapter 4.
  • Add music using the Attach Sound tool. Read how to use the Attach Sound tool in Acrobat’s Help files.
  • Set the document to open in Full Screen view (see Chapter 2).
  • Downsize the images in the finished presentation, producing a smaller file. This technique is discussed in Chapter 4.
  • E-mail the presentation to her client. This is covered later in this chapter.

Working With JPEG Images

JPEG (Joint Photographic Experts Group) is a file format often used with grayscale or color images, including photographs. It is a type of compression, which means the file size is reduced by combining the pixel content in different ways.

JPEG compression is called lossy compression because it removes image information from the file to make the file smaller in size. The compression process increases the size of pixels and applies a mathematical formula to approximate the color in each larger pixel. As a result, the quality of the image can be reduced. It’s important to strike a balance between the file size and the quality of the image.

Acrobat uses five levels of JPEG compression. Image quality and file size are inversely proportional. That is, the higher the quality of the image, the larger the file size; the lower the quality, the smaller the size.

Both high and maximum compression levels produce very clear, crisp images. On the other hand, Minimum and Low levels can be distorted and display a boxy appearance. Sometimes the distortion is so great it’s difficult to determine
