I run a mind numbing series of init's to get this to work for me. I currently use: ScreenMaster: This will load a copy of a graphic into memory and adjust the clut. Also provided is an init to reset the clut after the picture is desposed from the screen. (I leave this init out because I want the new clut to be remembered). DeskPicture: This will load the graphic again, but will retain it as the desk top picture. If you have DeskPicture load in the same graphic that was previously loaded in by ScreenMaster, then the clut is already loaded (something that DeskPicture will not do) ScreenMaster is ShareWare, and may do desktop pics sometime in the future. DeskPicture, I believe is in the Public Domain. I make the process more complex by having two minitors (one mono the other colour) and wanted to have backdrops on both monitors. Yes, this is possible. The init to do so, called ColorDesk, by Paul Mercer, is a comercial application and is available as part of the Screen Gems package. ColorDesk alows you to pick which monitor you want your desktop pic to reside on (a choice that other cdev/init's do not give you.. now if only it would do multiple monitors.. then I could throw away all my other inits.. yeh!!.. hows about it Paul?) | Thanks... Hope this helps. Stu. BTW, if I get inundated with requests to send ScreenMaster of DeskPicture to people, I'll post it to the comp.binaries.mac. __Paths to my door:______________________ stuartb@microsof.beaver.cs.washington.edu stuartb%microsof@uw-beaver.arpa stuartb@microsof.uucp _________________________________________ Usual disclaimer, that all the above is pure fantasy and Microsoft only gave me the Mountain Dew to dream it all in a caffeine haze :-{) :-{) _______________________________________________________________________
