To set GIF format options:
1
Select File > Export and select GIF from the Format menu.
2
Click Setup to view secondary options. For information about these options, see “Exporting
bitmap images” on page 352.
3
Click More.
4
Select the Interlaced option to create an image that is displayed in intermittent bands while the
full image is downloading.
5
Select an option from the Dither pop-up menu to simulate colors that are not in the current
palette. A higher dither setting simulates more colors but can increase file size.
6
Select an option from the Palette pop-up menu:
Exact Palette
creates a color palette for the exported GIF with only the colors used in the
selected object.
Note: The Exact and WebSnap Adaptive palettes do not support Transparency.
WebSafe 216
includes the standard, 216 Web-safe colors common to Windows and the
Macintosh and used by web browsers.
WebSnap Adaptive 256, 128, or 16
creates an adaptive palette of colors that are
converted (adapted) to the closest Web-safe color equivalent. WebSnap Adaptive 256 is
the default palette.
64 colors, 32 colors, or 16 colors
selects a preset color palette to quickly export smaller GIFs by
constraining the number of colors to a minimum. If the original colors differ from those in the
preset palettes, FreeHand approximates the colors and may produce inconsistent results.
3-3-2
uses the palette of the original FreeHand GIF Import Export Xtra.
Other
lets you use a Photoshop palette if you have installed one in your copy of FreeHand MX.
Navigate to the installed palette to select it.
Tip: To install a Photoshop palette file (with the extension .aco), place the file in the Palettes folder, which is in
the Macromedia/FreeHand/11/English/Settings folder inside your user-specific Application Data (Windows) or
Application Support (Macintosh) folder. Because the location of your user-specific Application Data or
Application Support folder varies depending on your operating system, refer to your operating system’s
documentation for information on how to locate it.
7
Select Optimized Palette to create the smallest file with the least number of colors, and remove
unused colors from the image’s palette.
8
Select Transparent Background to create transparency in a GIF based on objects’ outlines.
If you chose a palette other than Exact or WebSnap, the selected color for transparency is
highlighted in the palette, and its index number is displayed in the Index box. Boxes with
X’ s
indicate unused colors.
9
Define the transparency color by clicking a color swatch in the palette or entering its index
number.
10
Click OK.
11
If you selected Transparent Background in step 8, select Include Alpha Channel in the Bitmap
Export Defaults (Windows) or GIF Setup (Macintosh) dialog box.
12
Click OK, then click Save (Windows) or Export (Macintosh) to export the GIF image.
