Optimize; Interlacing; File Panel; Animation Panel - MACROMEDIA FIREWORKS 2-USING FIREWORKS Use Manual

One solution is to set the Fireworks canvas color to be
the same as the background color of the web page.
Another solution is to use the Matte color in the Export
Preview to change the canvas color during export to
match the background color of the web page. This way, a
commonly reused image can quickly be re-exported to
match a variety of web page background colors.
To set the matte color, select a color from the Matte pop-
up in the Export Preview. The matte color replaces the
canvas color in the exported image.

Optimize

Check Optimize to create the smallest file with the least
number of colors. Uncheck Optimize to include all
colors in the palette, whether or not they are used in the
exported image.

Interlacing

Check to make the exported GIF or PNG interlaced.
When viewed in a web browser, interlaced images
quickly appear at a low resolution and then transition to
full resolution as they continue to download.

File panel

Use the File panel to set the scale or exported area of the
exported document.
Scale
The Scale settings increase or decrease the size of the
image when exporting. Use either of two scaling
methods:
Enter a percentage or choose from the pop-up slider
to increase or decrease the exported image size by a
percentage. The W (width) and H (height) pixel
dimensions update automatically.
Enter numbers in the W and H fields to scale the
graphic to a specific pixel width and height.
Check Constrain to keep width and height proportional
when scaling.

Animation panel

Use the Animation panel when exporting an animated
GIF.
For more information about the Animation panel, see
