This document discusses various types of digital media and graphics technologies. It describes how image processing programs like Photoshop and iPhoto allow users to manipulate and combine photos. It also discusses object-oriented graphics formats like PDF, and how computer-aided design and manufacturing (CAD/CAM) technologies enable turning digital designs into physical products. The document also summarizes presentation graphics software for creating slideshows, data compression techniques, and hypertext and hypermedia technologies for linking multimedia content on the internet.

Image Processing: Photographic Editing
by Computer
 Image processing: users manipulate photographs
with tools such as Adobe Photoshop and Apple’s
iPhoto. Textbook pp. 193-194
 Can distort and combine photos
 Can create fabricated images that show no evidence
of tampering

Drawing: Object-Oriented Graphics
 KNOW YOUR GRAPHICS FORMATS!!
Textbook Page 196
 PDF (portable document format): file format
developed by Adobe; enables digital documents to
be exchanged between programs independent of
application software, hardware, or operating system
• Can contain text, fonts, images, and vector graphics
• Can be displayed by Web browsers using Adobe’s Acrobat
Reader

CAD/CAM: Turning Pictures into Products
 (CAD) computer-aided design: allows engineers,
designers, and architects create designs on screen
products ranging from computer chips to public
buildings
 Can test product prototypes
 Cheaper, faster, and more accurate than traditional
design-by-hand techniques

CAD/CAM: Turning Pictures into Products
 CAM (computer-aided
manufacturing): process by
which data related to the
product design are fed into a
program that controls the
manufacturing of parts
 CIM (computer-integrated
manufacturing): combination
of CAD/CAM

Presentation Graphics:
Bringing Lectures to Life
 Presentation graphics: automates creation of visual
aids for lectures, training sessions, sales
demonstrations, and other presentations
 Creates slideshows directly on computer monitors or
LCD projectors, including still images, animation, and
video clips
 Review textbook pages 202-203 on how to make
POWERFUL presentations. Details on next slide.

• Be smart with art
• Keep it simple
• Do test run before
making presentation
• Don’t read slides
• Pause when revealing
new slide or bullet

Data Compression
Saves storage space
i.e. “zipped” files
Textbook page 208
Windows can zip a file for you.
Just right click and choose the
option called “send to”

Hypertext and Hypermedia
 Hypertext: information linked in nonsequential ways
HTML (Hypertext Markup Language) See Handout
Programs like Microsoft FRONTPAGE
 Hypermedia: combines text, numbers, graphics,
animation, sound effects, music, and other media in
hyperlinked documents
• Enables the user to jump between documents
all over the Internet
Multimedia: combination of text, graphics, animation,
video, music, voice, and sound effects allows the user to
take an active part in the experience
