I want to have color pictures as startup screens an desktop but I encountered some problems. My questions: How can I make a a startup screen from a res=0 pict converted gif? Do I always need a cdev like ScreenMaster? For the desktop picture I used !DeskPict. But in both cases the pictures were displayed with the standard color lookup table (not the one of the original gif). I think that it should have it's own clut, right? But how do you get a clut in a pict file which is a conversion of a gif with Giffer 1.06. Where is the color information in a pict file If anybody knows the answers to my questions, please let me know.

You shouldn't need ScreenMaster, just rename the "res=0 pict" file to StartUpScreen and the next time you reboot you should see the picture instead of the "Welcome to Macintosh" dialog. >For the desktop picture I used !DeskPict.

Where is the color information in a pict file No, !DeskPict doesn't scan the PICT before displaying it to get the clut. It lets ColorQuick draw do the color mapping to the system CLUT. If you want an init/cdev that does change the CLUT to match the picture, go out and buy Now Utilities. One of the utilities is DeskPicture, the commercial version of !DeskPict. DeskPicture allows you change the system CLUT to that of the picture, it can read standard PICT files, has a preview mode that allows you to adjust the scaling, and also adds the option to a "virtual memory" type trick so instead of using 300k of RAM to store the image (for a 13" 256 color monitor) it will instead use 300k of disk space. Hope this helps a little.
