Tips for Working with Graphics

This section provides some tips for how to use graphics in Microsoft Word and Microsoft PowerPoint and contains several links to more information.

Choosing Your Graphic

There are two types of graphics to use, vector and bitmap. Generally, you should use vector graphics because they are easier to manipulate and because they are smaller in size, which creates a much smaller PDF file after conversion. Here's a quick guide to graphics:

bulletVector: These files are created with drawing packages that define objects as a series of lines and fills. Vector images resize very well, so they are the best types of images to put into PowerPoint. These are just a few of the common formats of vector graphics:
bulletWindows Metafile (WMF): This file format is used mainly to transfer graphical data between Microsoft Windows applications.
bulletComputer Graphics Metafile (CGM): A data format, developed in 1986 by ANSI and ISO, that can contain vector graphics, raster graphics, and text.
bulletEncapsulated PostScript (EPS): Usually a single-page description of a graphic in the PostScript language program. This file occasionally stores a bitmap preview that can be viewed on a Mac (in a PICT format), a PC (in TIF format), or a platform-independent machine (in EPSI format).

 

bulletBitmap: These are defined as a collection, or "map," of individual dots or pixels. Photographs and other scanned pictures are always rendered this way. To create, edit, or modify bitmaps, you need to use a photo-editing package, not Word or PowerPoint. Sizing is the number one problem with bitmaps because they look good at one size only. Once they have been resized, they tend to degrade in quality. Here are a few of the most common formats of bitmap graphics:
bulletWindows Bitmap (BMP): This is a device-independent rendering of a bitmap that can use up to 256 colors. Note that the files are generally not compressed.
bulletGraphics Interchange Format (GIF): Because this format can only display a maximum of 256 colors, it is best used for black-and-white line drawings, color clip art, and pictures with large blocks of solid colors.
bulletJoint Photographic Experts Group (JPEG): It is not limited to 256 colors, so you can use it to display high-quality photographs, or pictures containing millions of colors. Because it is designed as an image storage format, it can efficiently compress large, high-quality photos into very compact files, so it is very useful when you want to send a large image via e-mail. However, the more you reduce your image's file size (or modify and re-save the image), the more image information is discarded - and quality is decreased.
bulletTagged Image File Format (TIF): This is a very complex graphics file format, but it does allow for file compression.

Tips for Making Better Presentations

The following information was culled from several resources (listed below) to help you prepare your presentation.

Some tips for good visuals:

bulletVisible: Type should be at least 18 point. Three to 4 words per line is optimal.
bulletClear: Focus on one idea per transparency.
bulletSimple: Better to put in only keywords, not sentences.

Keep in mind that transparencies are summaries and visual aids to your talk - they do not need to contain every word you speak, but rather should be used to summarize difficult concepts.

If you're not sure how to present your data, try these styles of graphs:

bulletPie charts for percentages
bulletBar graphs (horizontal) or column charts (vertical) for comparisons and rankings.
bulletColumn or line charts for changes over time and frequency.
bulletBar graphs and dot charts for correlation.

Listeners often only pay attention to about 10% of your talk. To help them retain the number of facts and data you present, it is always a good idea to summarize your points, either periodically throughout the talk or at the end.

Tips for Converting Your Presentation to PDF

To create a PDF from both Microsoft Word 2000 and Microsoft PowerPoint 2000, click Acrobat > Convert to Adobe PDF.  If you do not have this toolbar item available, print your document to a single PostScript file (*.ps) and use Adobe Distiller to covert the PostScript file to PDF.

Tips for Scanning Nonelectronic Presentations

If you do not have a scanner to scan directly into PDF using an OCR scanner, it is best to scan your individual slides into a Tagged Image File Format (TIF) or similar kind of graphics file. Then print the image to a PostScript file and convert it to a PDF file by using Adobe Acrobat Distiller. This method allows for maximum image quality with minimum file size. All of your presentation slides can be concatenated into one PDF file by using the Add Pages function of Adobe Acrobat Exchange. (Distiller and Exchange are part of the Adobe Acrobat suite.)
