- Subject: [*]startupscreens and deskpicts FAQ
-
- Bill, My previous FAQ is a little out of date now -- could you please replace
- it with the following.
- ------------------------------
-
- Over the last year or so I've posted quite a few startupscreens to
- info-mac. One consequence of this is to get a flood of email asking
- questions about how to use the screens, how to create them and so on.
- The following is a list of answers to the most common questions.
-
- Frequently asked questions about startupscreens and desktop pictures.
-
- 1) I have a startupscreen, how do I get it to work?
-
- A-- Rename the file to "startupscreen" (no quotes) and put in in your
- system folder. The next time you reboot it will be displayed.
-
- 2) I tried that and the startupscreen looked terrible on my SE/30. All
- black and horrible.
-
- A-- You probably downloaded and tried to use a *colour* startupscreen.
- These look pretty poor on B&W screens. There are some decent B&W
- startupscreens around, why don't you try one of those? Or you could
- always make your own.
-
- 3) Great, so how do I make my own startupscreen?
-
- A-- A startupscreen is just a PICT file with ID=0 so to make your own
- you can take any PICT file and use ResEdit to change the ID to zero
- (open the PICT resource, get info, change the ID number to zero). The
- easy way is to use one of the painting/drawing applications that are able
- to save files as startupscreens. PixelPaint, SuperPaint, and GifConverter
- are a few examples of the many applications that can do this. However,
- ALL painting applications (and most GIF viewers) can save as PICT (the
- macintosh standard) so you can then use method 1 to get your startupscreen.
-
- 4) I tried using GifConverter to save as a startupscreen and all I got was an
- ugly black and white screen. Why?
-
- A-- When you save a colour GIF using GifConverter you must first go to
- Options... under the Special menu and set the startupscreen to Mac II
- (color) or it will default to B&W. BTW, don't forget that GifConverter
- is shareware.
-
- 5) I have this terrific GIF of Ronald Reagan bungee jumping naked (please
- don't email me asking for this, I just made it up) but when I made it
- into a startupscreen it looked terrible. Why?
-
- A-- Ronald never looks as good on the small screen, even fully dressed
- :-) No, the real reason involves the way colours are displayed on the
- screen. Colour monitors can actually display millions of colours but if
- you have a computer limited to 256 colours you can only display 256
- different colours *at the same time*. GIF programs select the 256 colours
- to best represent the GIF being viewed, which means for a picture of
- someones face the 256 colours might be mainly various shades of skin
- tones. Some GIFs look as clear as photographs because of this.
-
- Startupscreens use the 256 predetermined colours of the system palette.
- Thus, any GIF that has many shades of the same colour will usually make
- a poor startupscreen. For example, a person's face using 100 different
- shades of brown will be converted to the dozen shades of brown in the
- system palette with the loss of resolution.
-
- I have found that generally the best pictures for startupscreens are
- those with limited numbers of colours (eg. cartoons).
-
- 6) I have a bunch of cool startupscreens, can I use them as desktops as well?
-
- A-- Yes. Several utilities can do this. Deskpict (in the Sumex archive
- info-mac/ex/deskpict-11.hqx) and Backdrop (info-mac/ex/backdrop.hqx)
- are two examples in the shareware archives. A commercial version of
- Deskpict (a control panel called Deskpicture) comes bundled with several
- other very useful utilities in the Now Utilities package. There are other
- commercial extensions that do this also; shop around for the package that
- suits you best. Each of the above comes with instructions on how to get
- the deskpicture displayed. Beware, both Deskpict and Backdrop are quite
- old now and may not run well with system 7 and some extensions.
-
- 7) I've downloaded deskpict-11 from Sumex and now have a great desktop but
- my hard disk icon keeps disappearing, what gives?
-
- A-- You get what you pay for :-) Seriously, this is a known problem with
- Deskpict-11 and it has been solved with the commercial version (Now's
- Deskpicture) but is unlikely to be fixed with the old shareware version.
- Solutions? Put up with the missing/chopped-up icon or shell out for Now
- Utilities.
-
- 8) I have dozens of great startupscreens/deskpictures -- can I get a random
- one on each startup?
-
- A-- Yes you can. Now's Deskpicture is a control panel that allows random
- deskpictures on multiple screens. Or if you want to save a few bucks get
- Randomizer (info-mac/ex/randomizer-12.hqx) and follow these simple
- instructions. Create a folder in your system folder called Screens and
- put all your startupscreens in there (they can be named anything). Next,
- you need to put a screen in the system folder (called startupscreen).
- Then when you restart the startupscreen will be displayed and randomizer
- will select a random file from the Screens folder and rename it to
- "startupscreen" and overwrite your original screen ready for the next
- restart.
-
- For those who like to play with ResEdit, you can open up Randomizer,
- open the STR# resource, then open the STR# resource 2001 (Files then
- Folders). You will be presented with a list of strings with first the
- filename then the folder name (eg. for startupscreens the first string
- is startupscreen and the second is :Screens). You can add to these such
- things as Deskpicture and :deskpicts (to randomly choose a deskpicture
- from a folder called deskpicts), and sound and :soundfiles (to randomly
- choose a sound from a folder called soundfiles), and so on.
-
- While you have Randomizer open you can open the LAYO resource and set
- the "Pick files randomly" bit to either 1 (random) or 0 (sequential)
- depending on your taste.
-
- 9) OK, I braved ResEdit and did all that but now I'm not getting either a
- startupscreen or a deskpicture -- what happened?
-
- A-- You forgot to put an initial startupscreen and deskpicture in your
- system folder. Randomizer will only *overwrite* a file that's there, it
- will not create one from scratch.
-
- 10) My startupscreen is coming out black and white and looks gross, what
- gives?
-
- A-- I don't know why the technical reasons why this happens (and who
- cares anyway:-) but this is how you fix it. Go into the monitors control
- panel and set your monitor to black and white and then back to 256
- colours. Next time you reboot all should be well.
-
- 11) Now my mac looks awesome and my pee-cee friends are green with envy. How
- can I share my joy with the rest of the mac world.
-
- A-- If you find or create an especially nice startupscreen why not post
- it to info-mac and share it with everybody.
-
- 12) Well I decided to post a great GIF I found but when I stuffed/compacted
- the GIF it came out larger! What did I do wrong?
-
- A-- GIFs are already a compressed format (this is too complex to go into
- here) so trying to stuff them is like trying to stuff a compact pro
- archive -- it gets you nowhere. Post the binhexed GIF directly or, if
- you prefer, create the startupscreen and stuff/compact that and post it.
-
- 12) Where can I find a good supply of GIFs?
-
- A-- This is getting off the topic a little but wuarchive.wustl.edu
- stores several hundred GIFs (in binary format) if you want to look
- through them. Have fun.
