One of the convenient and unique features of the Mac OS is that you can apply your own custom icons to individual documents, folders, and volumes (disks). You can copy an icon from one item to another, create your own icons from picture files, or remove custom icons from items to return them to their generic appearance.

1.

Locate the Source Image

An icon can come from either of two places: a picture file copied to the Clipboard, or an existing icon copied from another document or folder. Decide where the icon is going to come from; open a Finder window and navigate to where that source item is.

2.

Copy the Source Image to Clipboard

To create an icon from a picture file, first open the picture in Preview (or any other picture-viewing application that allows you to copy image data to the Clipboard). Copy the picture to the Clipboard by choosing Edit, Copy or pressing .

TIP

You can view the contents of the Clipboard by switching to the Finder and then choosing Edit, Show Clipboard . If the picture has been successfully copied to the Clipboard, it will appear in the Clipboard window that opens.

17. Change an Icon


To copy an existing icon from another item, select that item and then choose File, Get Info (or press ). Use the mouse to select the icon in the top-left corner of the General pane of the Info window, and choose Edit, Copy or press to copy the icon to the Clipboard.

3.

Get Info on Item to Be Changed

Select the document or folder whose icon you want to change. Choose File, Get Info or press . Click the icon in the top-left corner of the General pane of the Info window.

4.

Paste Image into Icon

Press to paste the Clipboard's contents onto the item as its new icon.

NOTE

In Mac OS X, icons can contain 32-bit picture datared, green, blue, and alpha (transparency) channels, with 8 bits each. If a part of the icon image is transparent (the alpha channel is at maximum), that part of the icon will not be clickableclicking on that region will not select the icon. This means that if you apply a custom icon that's got a weird shape and not much non-transparent image data, it will be difficult to click the icon in the Finder.

For icons in the Dock, the whole square region of an icon responds to a click, whether it's transparent or not.

Icons in Mac OS X can be arbitrarily scaled to any size up to 128x128 pixels, so technically you only need a single image for an icon; however, icons often look best at 32x32, where some icons switch to a "lower-resolution" version for better readability at smaller sizes. Use an application like Iconographer (http://www.mscape.com) to create these multi- sized icons.

14 Create a Smart Folder That Contains Certain Types of Items


In Mac OS X, you can assign different colored "labels" to documents and folders. The meanings of these labels are up to you to definea blue label might mean "Incomplete projects" or "Items I haven't looked at yet," and red labels might signify "Documents from the Thompson account." Labels appear in the highlight color of an item's name , in an oval around the text. You can sort items in the Finder based on the label color, allowing you to group items conceptually without having to fiddle with their names or put them into folders. You can also use the color label as a search criterion in a Spotlight search or Smart Folder.

18. Set a Color Label


1.

Select the Item

In a Finder window, select the item you want to label.

TIP

You can label multiple items at once. Select as many items as you want, using the Shift or Command key in conjunction with mouse clicks, and then set the label color.

2.

Set the Label Color

From the File menu or the Action button menu, choose the Color Label you want to use. Seven colors are available to choose from; click the appropriate colored dot. You can also set the label by right-clicking (or Control +clicking) the item and selecting the label color from the contextual menu.

3.

Sort by Label in Icon View

In the Finder's Icon view, you can sort items by label color. After you have set different colored labels for several items within a folder, select View, View Options . In the View Options panel that opens, select the Keep arranged by check box and select Label from the drop-down menu to group items by their assigned label colors.

TIP

In Icon view, choose View, Arrange and then choose by Label to arrange the contents of a folder immediately into a well-organized grid sorted by the files' labels.

4.

Sort by Label in List View

You can also sort items by label colors in the Finder's list view. First make sure that the Label column is shown by opening the View Options panel (choose View, View Options ) and selecting the Label check box. Then, in the Finder window, scroll to the far right of the window and click the Label column heading to sort the list based on the assigned colors.

TIP

You can also make use of color labels when finding files. While building a Spotlight search in the Finder or creating a Smart Folder, create a criterion based on the Label ; you can then specify which color labels you want to look for, or which ones you want to avoid (using the is not clause). Create as many of these criteria as necessary to match the correct files.

5.

View Sorted Results

Although these examples are shown in black and white, the names of the label colors in the Finder's list view show how easily you can sort items in a folder based on label colors.

6.

Remove the Label

To clear a label you don't need anymore, select the item with the colored label you want to remove. From the File menu or the Action button menu, click the X under the Color Label option to remove the color. You can also access the Color Label options by right-clicking (or Control +clicking) to open the contextual menu.

You can assign special meanings to the various color labels. In the Finder Preferences , click the Labels tab; then, next to each color, type a new name for each label. For instance, you might make red signify "Overdue," and yellow signify "In-progress," to help you keep track of documents that you're working on over a long period of time. Without color labels, writing the chapters of this book would have been much more difficult!
