[comp.sys.mac] Startup Screens

rond@zaphod.UUCP (Ronald James Domes) (05/12/87)

I have heard rumor that, at one point in time, someone posted information
	on how to make startup screens. Could someone please send this to me.

  The last time I edited a startup screen, I used Superpaint. It works
wonderfully, but there is one other, Pixelpaint, that will be released soon
that works in COLOR...

A couple of questions regarding StartupScreens....

(1) After looking through some startup screens it looks like
they are just a bit image 342x512.  Is this true?

(2) Is it possible to use larger startup screens on the
MacII.  Also, on the MacII, is it possible to display a pixel
image rather than a bit image?

                                     Thanks heaps,

                                     Kevin Housen

    On all machines except Mac II's, yes, this is true.

    The Mac II ROM knows how to display a MacPlus-type
StartupScreen properly centered on the screen.  But you didn't
pay $5000 for that!  Much better, it will use any file with a
'PICT' resource of ID = 0 in its resource fork as a
StartupScreen.  The PICT can be any size and will be centered
on the screen.  It can be an old fashioned "Mac I" PICT or a
Mac II "PICT2" PICT, complete with color graphics.
    You can create one of these by selecting some graphics in
your favorite graphics program, copying it to the clipboard,
running ResEdit and pasting it into a resource of type 'PICT'.
Use GetInfo to set the ID to 0.
    You can also use Mac II specific programs that are
floating around now to create hundreds of gray scale and color
StartupScreens.  Such programs include Giffer, Pixel Paint,
Supervision (I believe), and my program, GrayView.

Yes, this was the original format for startup screens.  Not too bright,
as it requires them to use a fixed 22K of disk space.

On the Mac II (and the SE?  I don't know.), a startup screen can
alternatively consist of a file with a PICT resource number 0.  The PICT
is displayed centered on the screen.  Use of this method allows color or
gray-scale startup screens.

Excuse me for being ignorant, BUT.... :-)

	Exactly how do I create a startup screen using giffer??  I have tried
saving the picture and then renaming it StartUpScreen in my system folder, but
all I get when I start up is a box of black & white graphics/mess.
	Also, I would appreciate some info on how to convert graphic pictures
(especially color ones) so that I can use then as a desk background.  I have
DeskPict and it works great, but the only background picture I can get is the
one that comes up in the DeskPict init screen.  It seems to need a picture
with a PICT resource, and all the pictures that I am able to access only
have a data fork with no resource fork.
	I have LOTS of experience with computer systems, but I am just starting
to work with some of the MAC II resource stuff (That explains the ignorance!).
Any hints anybody could give me would be greatly appreciated.

Thanks

If deskpict is public domain, could someone please mail it to me.
