FIREWORKS CURRICULUM
Canvas color
The canvas is the bottom layer of your document, under the Background layer. Transparent areas of the
background layer appear as the canvas color. You can choose a white canvas, a transparent canvas, or a
color canvas in the New Document dialog box (Figure 1-18).
Fireworks will anti-alias to your canvas color, so for most pleasing results set your canvas color to the
background color of your Web page.
Figure 1-18
Be sure to set the resolution properly in the New Document dialog box. Once your
document’s resolution has been set, it cannot be changed.
Number of undo steps
Choose Edit > Undo to reverse an action. Enter a value of up to 100 in the File > Preferences >
General > “Undo Steps” field.
Note that RAM requirements increase as the number of undo steps increases. The recommended
setting for the Undo preferences is 8.
Changes to the Undo preference do not take effect until Fireworks is restarted.
Often when working with a custom page color and file format that support
transparency (such as GIF), it is advisable to create Web graphics with a
transparent canvas. However, it can be visually difficult to create graphics
against the checkerboard pattern that indicates transparency. Instead try
creating your graphics with a white canvas and changing the canvas later
by choosing Modify > Document > Canvas Color.
