ADOBE FIREWORKS CS3 263 User Guide GIF Adaptive 256 is a color palette that contains only the actual colors used in the graphic. The color palette contains up to a maximum of 256 colors. JPEG - Better Quality sets quality to 80 and smoothing to 0, resulting in a high-quality but larger graphic. JPEG - Smaller File sets quality to 60 and smoothing to 2, resulting in a graphic less than half the size of a Better Quality JPEG but with reduced quality. Animated GIF Websnap 128 sets the file format to Animated GIF and converts non-websafe colors to their closest websafe color. The color palette contains up to 128 colors. For more information about file types, see "Choosing a file type" on page 265. To specify custom optimization settings: 1 In the Optimize panel, select an option from the Export File Format pop-up menu. 2 Set format-specific options, such as color depth, dither, and quality. 3 Select other optimization settings from the Optimize panel Options menu, as necessary. For more information about specific optimization controls, see the appropriate sections in "Optimizing in the workspace" on page 261. 4 You can name and save custom optimization settings. Names of saved settings are displayed in the preset optimization settings in the Settings pop-up menu in the Optimize panel and the Property inspector when slices, buttons, or the canvas are selected. For more information, see "Saving and reusing optimization settings" on page 275. To modify the color palette: ❖ If the Optimize panel isn't already open, select Window > Optimize to view and edit a document's color palette. For more information, see "Optimizing GIF, PNG, TIFF, BMP, and PICT files" on page 265. To optimize individual slices: 1 Click a slice to select it. Shift-click to select more than one slice. 2 Optimize the selected slices using the Optimize panel. Previewing and comparing optimization settings The document preview buttons display the graphic as it would appear in a web browser, based on optimization settings. You can preview rollover and navigation behaviors, as well as animation. The Original button and the document preview buttons The document preview buttons display a document's total size, estimated download time, and file format. The estimated download time is the average amount of time it would take to download all the document's slices and frames on a 56K modem. The 2-Up and 4-Up views display additional information that varies depending on the file type selected. You can use the Optimize panel to optimize a document while viewing a preview as if you were in Original view. You can optimize the entire document at once or only selected slices. The slice overlay helps you differentiate the slices currently being optimized from the rest of the document. The slice overlay displays areas not currently being optimized with a dimmed, transparent white tint. You can turn the slice overlay on or off.
