For X bitmap format stuff, use "xsetroot -bitmap foo.bitmap".  If the
bitmap is large enough for a full-screen background, however, you'll
run into bitmap size limitations in XReadBitmapFile().  I fixed it
with the following simple tweak in XReadBitmapF.c:

diff XReadBitmapF.c ../Xlib/XReadBitmapF.c
30c30
<     while ((status = fscanf (file, "#define %80s %d\n", variable, &value))==2)
---
>     while ((status = fscanf (file, "#define %80s %2d\n", variable, &value))==2
)

Apparently the author expected bitmaps to be no larger than 99x99,
which makes for a pretty small full-screen background.

If you want to use Sun rasterfiles, get a translator called "suntox",
which was posted by clyde@ut-ngp.UUCP on 3 Mar 87.  Another way would
be to bother Ed Neiters at Purdue for his "xbgsun" which takes a Sun
rasterfile and translates it on the fly to an X bitmap, as it's being
sent to the server.
