- Introduction
-
-
-
- Fade to Black is a Desk Accessory designed to save your Macintosh screen.
- It's possible for the image on a computer's screen to get "stuck" when it is
- displayed for a long time, and remain visible, even when something else is on
- the screen. This is more of a problem on a Mac than other computers, because
- much of the Macintosh's screen is white. But the problem is also easier to
- solve on a Mac than other computers, because of the flexibility of the Mac's
- operating system. This is what Fade to Black does.
-
-
-
- Fade to Black works by waiting quietly until you haven't used your Macintosh
- for a while, and then causes the screen to slowly fade to black, so the image
- that was being displayed won't become permanent. To let you know that your
- Mac's still alive, a copy of the current application's icon floats around the
- screen. When you want to use the Mac again, simply click the mouse button or
- press a key, and the screen will be restored.
-
-
-
- Using Fade to Black
-
-
-
- Fade to Black is simple to use. First, install it on any system disks you
- have. Because some software may not work with Fade to Black, you should
- always install Fade to Black on a copy of the disk, not the original. To
- install it, use the Font/DA Mover to copy Fade to Black to the system file
- on your disks.
-
-
-
- The first time you select Fade to Black from the menu, a small routine
- (known as an INIT resource) will be copied from the desk accessory to the
- system file. This routine allows Fade to Black to run automatically
- whenever you boot from the disk with Fade to Black on it.
-
-
-
- If your Macintosh beeps when you open Fade to Black, the INIT resource
- couldn't be placed in your system file. One possible cause of this is that
- you already have too many INIT resources (only 32 are allowed). For most
- people, this won't occur (most system files normally have five to ten INIT
- resources). The most common cause is simply that the disk containing the
- system file is write protected. In this case, the routine has been placed in
- memory, but not on disk, so it will remain only until you reboot.
-
-
-
- When you have selected Fade to Black, and the INIT resource has been written
- to disk if necessary, a dialog box will be displayed which allows you to set
- the time delay to wait before fading, whether or not to make Fade to Black
- permanent, and a button which allows you to Fade... immediately. The
- permanent item allows you to specify whether or not Fade to Black should
- fade the screen automatically. If it isn't checked, you will have to manually
- fade the screen by clicking in the Fade box. If the permanent item is
- checked, Fade to Black will wait until you haven't typed a key, or pressed
- the mouse button, for the delay time specified.
-
-
-
- When you have set the delay time and the permanent status, you can save the
- values to disk by clicking in the OK box. If the disk containing the system
- file is write protected, the values will only be saved in memory, and will be
- lost when you reboot.
-
-
-
- If you change the values of the delay time or the permanent status, and don't
- wish to save the changes, you can click in the Cancel box.
-
-
-
- To cause the screen to fade immediately, you can click in the Fade box. Any
- changes you have made to the delay time or permanent status will not be saved.
-
-
-
- Once the screen is cleared, you can restore the screen's contents by typing a
- key, or clicking the mouse button. The key or the mouse click will not be
- seen by whatever application is running. If you are in MacWrite for instance,
- the key you type will not be entered in your text.
-
-
-
- Shortcuts
-
-
-
- When the Fade to Black dialog box is being displayed, you can use two
- shortcuts. First, you can press the Return key. This is the same as clicking
- in the OK box. You can change either the delay time, or the permanent status,
- and then press Return, and it will be saved to disk as if you clicked in the
- OK box.
-
-
-
- Second, pressing Enter is the same as clicking in the Fade box. To quickly
- fade the screen, you can select Fade to Black from the menu, and press
- enter to fade the screen.
-
-
-
- When the screen has faded, and the application's icon is being displayed,
- holding down the Option key will cause the screen to be restored. When you
- release the Option key, the screen will quickly be cleared. While the Option
- key is held down, the application that is running will be active. You can
- then work with the application, and even quit or transfer to another
- application. When the Option key is released, the screen will be cleared and
- the current application's icon will be displayed.
-
-
-
- Removing Fade to Black
-
-
-
- If you should ever want to remove Fade to Black, you can simply remove it
- using the Font/DA Mover. The next time you boot from the disk that used to
- contain the desk accessory, the INIT resource will recognize that you removed
- Fade to Black, and will remove itself.
-
-
-
- Compatibility
-
-
-
- Fade to Black has been tested with a number of applications, such as the
- MiniFinder, MacTerminal, and Switcher, although it is impossible to test it
- with every application. In general, if an application provides an menu and
- allows desk accessories to be selected, it should work with Fade to Black.
- If the application doesn't allow desk accessories, Fade to Black may still
- clear the screen automatically, but of course you won't be able to select
- Fade to Black and change the delay value or the permanent status. Such is
- the case with the MiniFinder.
-
-
-
- Fade to Black takes approximately 1300 bytes on the application heap, when
- it has been selected from the menu, and 900 bytes on the system heap, so
- some applications which allocate all of the memory they can get will not work
- with Fade to Black.
-
-
-
- Passing on Fade to Black
-
-
-
- Everyone is encouraged to pass on Fade to Black, as long as you pass on this
- documentation as well as the desk accessory, and my name, the version number,
- and the copyright date remain intact in the dialog box. You may not sell
- Fade to Black, or use it as an inducement to purchase another product.

- but even if you don't send any money, feel free to use it. You're under no
- obligation to send me anything (although it would be appreciated). My address
- is:
