Inserting Diagrams 455
● Relationship These show convergent, divergent, overlapping, merging, or containing
elements—for example, how organizing your e-mail, calendar, and contacts can
converge to improve your productivity.
On a slide that includes a content placeholder, you can click the placeholder’s Insert
SmartArt Graphic button to start the process of creating a diagram. You can also click
the SmartArt button in the Illustrations Group on the Insert tab to add a diagram to any
slide. In either case, you then select the type of diagram you want to create and click a
specific layout to see a picture and description. When you find the diagram that best
conveys your information, you click OK to insert the diagram with placeholder text that
you can replace in an adjacent Text pane.Graphic Formats
You can use picture and clip art files in a variety of formats, including the following:
● BMP (bitmap) This format stores graphics as a series of dots, or pixels. There
are different qualities of BMP, reflecting the number of bits available per pixel
to store information about the graphic—the greater the number of bits, the
greater the number of possible colors.
● GIF (Graphics Interchange Format) This format is common for images that
appear on Web pages because they can be compressed with no loss of
information and groups of them can be animated. GIFs store at most 8 bits
per pixel, so they are limited to 256 colors.
● JPEG (Joint Photographic Experts Group) This compressed format works
well for complex graphics such as scanned photographs. Some information is
lost in the compression process, but often the loss is imperceptible to the human
eye. Color JPEG images store 24 bits per pixel, so they are capable of displaying
more than 16 million colors. Grayscale JPEG images store 8 bits per pixel.
● TIFF (Tag Image File Format) This format can store compressed images with
a flexible number of bits per pixel. Using tags, a single multipage TIFF file can
store several images, along with related information such as type of compression
and orientation.
● PNG (Portable Network Graphic) This format has the advantages of the
GIF format but can store colors with 8, 24, or 48 bits per pixel and grayscales
with 1, 2, 4, 8, or 16 bits per pixel. A PNG file can also specify whether each
pixel blends with its background color and can contain color correction
information so that images look accurate on a broad range of display devices.
Graphics saved in this format are smaller, so they display faster.
