[comp.sys.mac.misc] giffer -> StartUpScreen?

gt4586c@prism.gatech.EDU (WILLETT,THOMAS CARTER) (08/11/90)

Since I obtained Giffer 1.06, I've been having great fun looking at 
nifty color pictures.  I noticed you can save the gif pictures into
the res id=0 pict format, i.e. a PICT resource which can then be
pasted into the StartupScreen's PICT resource, thus giving you your
favorite picture as a startupscreen.  However, when doing this I loose
a great deal of color resolution.  The original picture was done in
256 colors, but the PICT lookes like 16 colors.  Why have I lost    
resolution in this process?  Any ideas would be greatly appreciated.

Startupscreens use the system CLUT, so if the picture was originally done
in some other CLUT (for instance an earth tone or flesh tone or greyscale CLUT)
you will lose a lot of information.
