Gidday,
We have a client with a Quantal Harriet/Paintbox & would like
to read floppies written on this system using a PC to enable us
to use the pictures as bitmaps. Currently we have to record to
BetaSP then frame grab.
The floppies are 3 & 1/2 inch High Density floppies. 
I have tried reading some floppies on the PC without success (not suprising).
Thanks

This is UNIX refer format.  The "addbib" man page lists these tokens:

          %A   Author's name
          %B   Book containing article referenced
          %C   City (place of publication)
          %D   Date of publication

          %F   Footnote number or label (supplied by refer)
          %G   Government order number
          %H   Header commentary, printed before reference
          %I   Issuer (publisher)
          %J   Journal containing article
          %K   Keywords to use in locating reference
          %L   Label field used by -k option of refer
          %M   Bell Labs Memorandum (undefined)
          %N   Number within volume
          %O   Other commentary, printed at end of reference
          %P   Page number(s)
          %Q   Corporate or Foreign Author (unreversed)
          %R   Report, paper, or thesis (unpublished)
          %S   Series title
          %T   Title of article or book
          %V   Volume number
          %X   Abstract - used by roffbib, not by refer
          %Y,Z ignored by refer

Refer is a (somewhat) primitive set of tools for editing, sorting, and
printing bibliographies that use these tokens.  It comes free with most UNIX
systems.  Type "man refer" on a UNIX system for more info.

I'm posting this for a friend of mine. Please don't reply to the above

=============================================================================

I need a library that will allow applications I am developing to read and
write TIFF files.   I am using IBM PCs running MS-DOS, with the Microsoft and
WATCOM/386 compilers.  I am aware of one commercial product that handles TIFF,
but it cannot cope with the very large images I am working with (27,000 by
16,000 bilevel TIFF).  I am also investigating Sam Leffler's public domain
TIFF package, but I won't know whether that will work until I finish porting
it to MS-DOS.  Does anyone know of any other TIFF libraries, either commercial
or public domain, for my platform?

I'm all for splitting SIGGRAPH off from ACM -- that way ACM could form
a new organization that would concentrate on the academic and research
aspects of computer graphics, as opposed to the show biz.

To convert grey scale:

	<new pixel value> = <white pixel value> - <old pixel value>

To convert colour images:

	<new red pixel value> = <max red pixel value> - <old red pixel value>
	<new blue pixel value> = <max blue pixel value> - <old blue pixel value>
	<new green pixel value> = <max green pixel value> - <old green pixel value>

The colour version seems to lose contrast and have an unwanted tinge. 
We are currently trying to overcome this.

conversion process I lost all of the resolution.  
Does anyone know of a tool that might help preserve resolution while

I'm looking for software that will allow an arbitrary application to
extract data from a digitized document.

For example, given the digitized image of a completed paper form with
check-boxes, hand-written numbers, and free-form text, I want to enter
the data represented on that form into my database (FoxPro, Oracle, etc).

So basically, this software would need to be able to identify a check mark

Can somebody help me?

We did this in our stereo X Windows implementation. If done properly,
the flicker is not very bad. We felt that there was no contest in
deciding between slightly more flicker and regaining the full frame 
resolution. Although, since we were able to get a patent on the
technique, maybe we did it differently than it has been done before.
We use our stereo X Windows for the display of stereo satellite images 
and digitized airphotos, with stereo digital map information overlayed.
You can digitize and manipulate the overlayed map information using
a stereo cursor, so you're looking at the monitor fairly intently, and
the flicker doesn't seem too bad. Perhaps it might get tiring after
several hours of intensive work.

	(3) Models produced should consist of actual POLYGONS and not
            simply vertex drawing lists.

        (4) Should support digitizer tablet input.



    I am also looking for a paint package that will allow me to scan in
  photographs and perform hand retouching of the photos.  I would really
  appreciate any recommendations on possible packages for these purposes.
