FLASH CS3 485 User Guide • Use mp3, the smallest sound format, whenever possible. Optimize elements and lines • Group elements. • Use layers to separate elements that change during the animation from elements that do not. • Use Modify > Shape > Optimize to minimize the number of separate lines that are used to describe shapes. • Limit the number of special line types, such as dashed, dotted, ragged, and so on. Solid lines require less memory. Lines created with the Pencil tool require less memory than brush strokes. Optimize text and fonts • Limit the number of fonts and font styles. Use embedded fonts sparingly because they increase file size. • For Embed Fonts options, select only the characters needed instead of including the entire font. Optimize colors • Use the Color menu in the Symbol Property inspector to create many instances of a single symbol in different colors. • Use the Color panel (Window > Color) to match the color palette of the document to a browser-specific palette. • Use gradients sparingly. Filling an area with gradient color requires about 50 bytes more than filling it with solid color. • Use alpha transparency sparingly because it can slow playback. Speed up document display To speed up the document display, use commands in the View menu to turn off rendering-quality features that require extra computing and slow down document display. None of these commands have any effect on how Flash exports a document. To specify the display quality of Flash documents in a web browser, use the object and embed parameters. The Publish command can do this for you automatically. ❖ Select View > Preview Mode, and select from the following options: Outlines Displays only the outlines of the shapes in your scene and causes all lines to appear as thin lines. This makes it easier to reshape your graphic elements and to display complex scenes quickly. Fast Turns off anti-aliasing and displays all the colors and line styles of your drawing. Antialias Turns on anti-aliasing for lines, shapes, and bitmaps and displays shapes and lines so that their edges appear smoother on the screen. Draws more slowly than the Fast option. Anti-aliasing works best on video cards that provide thousands (16-bit) or millions (24-bit) of colors. In 16- or 256-color mode, black lines are smoothed, but colors might look better in Fast mode. Antialias Text Smooths the edges of any text. Works best with large font sizes and can be slow with large amounts of text. This is the most common mode in which to work. Full Renders all content on the Stage fully. Might slow down display. See also "Publishing overview" on page 418
