Transparency

Using Fireworks, create web graphics with fine-tuned
transparencies. Transparency is supported in two
graphic formats: GIF and PNG.

GIF transparency

Transparency is defined in GIF files by designating one
or more colors to be transparent. The designated color is
transparent when the GIF is viewed in a browser.
Use the Export Preview to set or adjust the transparent
area in a GIF. Use the Transparency Eyedropper tools to
add or remove colors from the transparent area.

PNG alpha transparency

Exported PNG files can contain alpha transparency
settings. Alpha transparency is different from GIF
transparency in that gradient levels of transparency can
be specified. This means that pixels may be set to blend
with the web browser's background color or
background image.
However, alpha transparency is not supported fully by
current browsers. Netscape Navigator 4.04 supports
PNG, but not alpha channels. Microsoft Internet
Explorer 4 partially supports PNG alpha channels, but
sometimes displays inconsistently when complex
gradient transparency is defined.
