→If your application includes a sidebar (or source list), you need to design icons to display in it. For example, the Mail mailbox list contains several icons that represent the user’s mailboxes, feeds, and reminders.

→Designing Sidebar Icons

→Although you use the straight-on perspective for the icon buttons you design, if you use a recognizable icon from elsewhere in the interface in your toolbar, you should not change its appearance or perspective. That is, don’t redesign a toolbar version of a well-known interface element.

→● Create an icon that measures 32 x 32 pixels

→● Use the PDF format

→● Use color judiciously to add meaning

→● Use anti-aliasing

→● Make the outline sharp and clear

→● Use a straight-on perspective

→Note: Mac OS X does not provide programming interfaces that support adding a custom cover flow experience to your app.

→The Mail icon includes a cancellation mark that extends past the bottom edge of the stamp image (you can see this icon in the figure below). Because this area of the icon has high alpha levels, the Finder uses an opaque pixel at the bottom left corner of the stamp image to align the icon, clipping some of the cancellation mark, as shown below.

→In Cover Flow view, the Finder positions icons so that they appear to be on the same plane. To do this, the Finder begins examining an icon at the bottom edge, looking for pixels that are opaque enough to use for alignment. If there is significant transparency in the lower area of your icon, the Finder ignores the transparent pixels in favor of the first opaque pixel it finds. The Finder uses the opaque pixel to determine the icon’s alignment with respect to the plane and may clip the transparent pixels below it.
