Compressing graphics
A picture, so they say, is worth a thousand words. Whether it’s worth
a thousand words or merely 950 is debatable. What is certain is
that visuals help people remember things. A carefully chosen image in a
PowerPoint presentation, Word document, or Excel worksheet helps others
understand you better. The image reinforces the ideas or information that
you’re trying to put across.
This chapter explains how you can make pictures — photographs, graphics,
and clip art — part of your Word documents, PowerPoint presentations, and
Excel worksheets. It looks into graphic file formats and other issues
pertaining to graphics as well as how to touch up graphics in an Office application.
All about Picture File Formats
Graphics and photographs come in many different file formats, and as far as
Office 2013 is concerned, some are better than others. These pages explain
what you need to know about graphic files to use them wisely in Office files.
Here, you find out what bitmap and vector graphics are, what resolution
and color depth are, and how graphic files are compressed.
Bitmap and vector graphics
All graphic images fall into either the bitmap or vector category:
A bitmap graphic is composed of thousands upon thousands of tiny dots
called pixels that, taken together, form an image (the term “pixel” comes
from “picture element”). A photograph is a bitmap graphic.
A vector graphic is drawn with the aid of computer instructions that
describe the shape and dimension of each line, curve, circle, and so on.
A clip-art image is a vector graphic.
