240 Chapter 12: Optimizing and Exporting
To force a color to its closest websafe equivalent:
1 Select a color in the Optimize panel color table.
2 Click the Snap to Web Safe button.
If you save a Fireworks PNG, changing colors to websafe in the Optimize panel affects only the
exported version of the image, not the actual image.
Saving palettes
You can save custom palettes as external palette files. You can use saved palettes with other
Fireworks documents or in other applications that support external palette files, such as
Macromedia FreeHand, Macromedia Flash, and Adobe Photoshop. Saved palette files have the
.act extension.
To save a custom color palette:
1 Choose Save Palette from the Optimize panel Options menu.
2 Type a name for the palette and choose a destination folder.
3 Click Save.
You can load the saved palette file into the Swatches panel or Optimize panel for use when
exporting other documents.
Adjusting compression
You can compress GIF files to make them even smaller than usual by changing their loss setting.
Higher loss settings can yield smaller files but lower image quality. A loss setting between 5 and
15 typically yields the best results.
Original GIF; loss value of 30; loss value of 100
To change a GIF’s compression:
• Enter a Loss setting in the Optimize panel.
