Hello, Is there any way to use a color rasterfile as the root in X11R3? (I'm on a sparcstation with an 8bit color monitor). I have these nice color scanned images I would like to use as root, but xsetroot only seems to know about b/w bitmaps. +----------------+----------------------------------------------------------+ | Joel Spolsky | bitnet: spolsky@yalecs.bitnet uucp: ...!yale!spolsky | | | internet: spolsky@cs.yale.edu voicenet: 203-436-1538 | +----------------+----------------------------------------------------------+ #include <disclaimer.h>

It was posted to comp.sources.x not so long ago and works very well. Does a nice job of dithering a greyscale image on a monochrome screen as well. It accepts images in a range of different formats including Sun rasterfiles.

Yes, it's called xgifroot, which, as you might surmise, requires gif format files. Use pbm(plus) to convert your tiff files to gif.

The "Img" package includes a program named "setback" that does this. BTW, the latest copy of this software is now on expo.lcs.mit.edu's contrib directory as "img.tar.Z". It's bloated to ~1.4 MB. because it includes one sample image for each of four sorts of images (24-bit RGB, color mapped, grayscale, & monochrome). Since the images stay in compressed form, the tar file grows by about 100K when it's uncompressed. ---------------- Paul Raveling Raveling@isi.edu

If you're putting color images on the root window with xloadimage, watch for patch 03 which should be out Real Soon Now. I modified the color allocation scheme to avoid private colors for many cases, which really helps when loading images onto the root. I recognized the private colormap cell allocation as a deficiency but was working on an intelligent way to do shareable color allocations without loosing the flexibility that I got from the private colors. The new patch will also fix a good many bugs (I sucked the source through Saber C and was disgusted with myself) and will work on a wider range of displays than it did under patchlevel 02. Watch for a real announcement here in a few days. Until then, thanks for the support that everyone has given me. jim frost saber software jimf@saber.com
