Sun - Java Look and Feel Design Guidelines, 2nd Edition made by dotneter@teamfly Don’t mix two- and three-dimensional styles in the same icon family. Use the flush 3D style so that your icons suit the Java look and feel. For more on the flush 3D style, see Producing the Flush 3D Effect. Because icons must appear on various backgrounds across platforms, the borders of graphics must maintain consistent color. Changing the appearance of an object’s border to look smoother at screen resolution in relationship to a specific color is called anti-aliasing. In most application development cases, anti-aliasing is not desirable because you are unlikely to be sure what background color the object will appear against. However, within an icon, anti-aliasing can provide smoother interior lines. For satisfactory display on a wide range of background colors and textures, use a clear, dark exterior border and ensure that there is no anti-aliasing or other detail around the perimeter of the graphic. Drawing Icons The following section uses a simple folder as an example of how to draw an icon. Before you start, decide on a general design for the object. In this example, a hanging file folder is used to represent a directory. 1. Draw a basic outline shape first. Icons can use as much of the available space as possible because they are displayed without borders. Icons should usually be centered horizontally in the available space. For vertical spacing, consider aligning to the lower edge of other icons in the set, or aligning with the baseline of text, as shown in the figure. If multiple sizes of an icon are required, work on them at the same time rather than trying to scale down a large icon later; all sizes then can evolve into designs that are
