The wbimport distribution README file

Wed Aug  4 02:52:58 PDT 1993

This is a quick hack to help with giving seminars via wb.  It also lets
you stuff scanned images or X window dumps into wb.  There should be 4
files here:

  - 'wbimport' is the program that coordinates the scanning & pokes
    wb to give it the resulting file.

  - 'doWbScan' is a shell script invoked by wbimport to actually do
    the scan.  It should produce postscript & send its output to
    stdout.

  - 'doWbXwd' is a shell script invoked by wbimport to do an X window
    dump of some window on the current screen & convert it to postscript.

  - lzps is a program to convert random postscript files into LZ compressed
    level-2 postscript (which gs & some new printers can deal with).  This
    is used by the doWbScan & doWbXwd to compress the ps files & save net
    bandwidth.

(the "start" program from the previous wbimport release is no longer
needed -- wbimport searches for a "wb" window when it comes up and,
if there's more than one, asks which you want.)

Wbimport can also be used if you have a set of postscript files that
you would like to import into wb in some sequence (eg., for a prepared
presentation).  If you put the postscript file names in a file where
each line has the format:

	 

(if  is omitted,  is used as the label) then start
wbimport giving the name of that file, a 'listbox' showing each label
will be displayed.  If you click on a label, the associated postscript
file will be imported into wb.  Once a file has been imported once,
its wb page number will be placed after the label & whenever you again
click on the label, wb will simply switch to that page (the file will
only be imported once).  For example, say you're giving a talk on
domestic animals and want to use postscript animal pictures you have
laying around.  Create a file called "animals" containing:

	dog  rover.ps
	cat  ~/images/tabby.ps
	tiger  /usr/local/lib/ghostscript/examples/tiger.ps

Then start wbimport like "wbimport animals" and you should see a
small window containing the names "dog", "cat" and "tiger".  Click
on one of the names & the associated file should be rendered in wb.
If the page has already been rendered, wb will flip to that page
NOTE that the page change command is sent to the net so *all* wb's
will flip to that page, not just the local wb.  DON'T use wbimport
to browse through the pages of a conference or you will make the
other members very angry with you.
