6 . 5 Integrating Text and Graphics
The integration of text and graphics is probably the single most problematic issue in electronic publishing. Document processing systems take many different approaches to the problems involved. Some systems import the graphics into the document. Others point to external files. Others convert the graphics into an internal format. Some allow graphics editing; others do not. Invariably, each document processing system has its own level of understanding of the graphics formats it can use. The formats themselves impose restrictions on the ultimate flexibility possible.
6 . 5 . 2 WYSIWYG Integration
Some document processing systems, usually the higherend systems, attempt to display the graphic on the screen with the text. The manipulation of these graphics varies widely, ranging from no manipulation to total control. One important characteristic is whether the graphics are treated as an unbreakable block or whether the system supports some amount of graphic editing. In addition, some systems have an internal set of graphics. For example, FrameMaker has, roughly put, the equivalent to MacDraw built in, but without bitmapped image manipulation capabilities.
The placement of graphics and how the graphics should flow, visually and logically, within the text is a major design issue for page layout and document processing systems. The classic page layout system typified by PageMaker allows a high degree of textual integration with the graphics. You simply drag the graphic into an area of text, and the system will visually flow the text around the graphic. The control of such run-arounds gives the document designer a great deal of freedom. (See Section 3 . 1 . 4 Page in Chapter 3 Points of View for an illustration of text flowing around a graphic.)
Some systems allow graphics to be anchored to text; as new text is inserted or deleted, the graphic remains attached to the correct place in the text. Another form of anchoring is to attach the graphic to a particular location on a page, such as the top of the page.
WYSIWYG publishing systems differ in many subtle ways. The ability of a system to incorporate graphics into an integrated document is an area in which these differences can make a real difference in your publishing job. Keep an eye out for the types of graphic manipulations allowed and how the system handles external file references.

6 . 5 . 3 Inline versus External on the Web
As we've just concluded our discussion of language versus WYSIWYG, it is appropriate to compare the two integration mechanisms available for Web browsing. In much the same way that document processing systems have evolved from languages to WYSIWYG, Web browsers are evolving from a collection of loosely integrated "helper" applications to tighter integrated inline systems.
Lost in all the technical whiz-bang demos and slick Web pages we see is the supremely important issue of the user interface. The most significant problem with the external helper application approach is the change in user interface that a user must endure. One second you're happily clicking on links and the next moment some foreign application pops up and you must figure out what to do. Of course, the use of external applications is a good way of distributing new types of data formats before going through the labor of integrating that data type with your browse
