SYMPTOMS
When you view a PowerPoint slide show, text that is displayed in slides that contain animations may appear choppy with jagged edges. The jagged appearance is especially noticeable in letters such as O,W, and R, and in slides that use Arial fonts where the text is white and the background of the slide is black. Text in slides that do not contain any animations looks fine, and appears smooth with no jagged edges.



CAUSE
The jagged appearance of text is caused by aliasing. Aliasing occurs when diagonal and curved lines are displayed as a series of smaller zigzag horizontal and vertical lines.



WORKAROUND
To work around this problem, use a different color scheme for your presentation. Using dark colors for text and light colors for the slide background can reduce the effect of aliasing and improve the appearance of text in your slides.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
As of March 2003, GDIPlus text rendering has not been implemented in Office 2002. Anti-aliasing is the name that is used for techniques that are designed to reduce or rule out this effect. Anti-aliasing blurs jagged edges by shading the pixels that are along the borders of graphical elements. Anti-aliasing depends on screens that can display many colors. Color schemes must be able to handle a wide range of shades between any two arbitrary text and background colors.
