The Art of lossless image compression, 4th release

Here are the results of 10 (ten) tests performed
to compare lossless compression of True Color (24-bit) images
by some general purpose archivers:
ERI32 3.0d, UFA32 0.03b4, RKIVE 1.90b1, ESP 1.92, RAR 2.02, PKZIP 2.04g
                           (sorry, BOA, UHARC, HAP, SZIP and all
                           other archivers were not tested)
and results on same images of the famous PNG algorithm and format
created by Display 1.89a, CompuShow 2000! 2.04a, Image Alchemy 1.10.
See Archive Comparison Test by Jeff Gilchrist for more details:
      http://www.geocities.com/SiliconValley/Park/4264/act.html
If anybody wants to start or continue such tests,
or can suggest some other sets of images, or other compression programs,
     (not sources or algorithm descriptions ; programs for DOS or Windows only)
or knows we have missed something important,
     (some new fantastic technology, an algorithm or even a program capable
      of lossless compression of up to 1000:1 and lossy compression of
      up to 10000:1 , we hear about it from time to time since our XTs)
please let us know immediately: ratush@srsc-gw.sscc.ru   Thanks!

1,2,3,4,9 image sets were taken from ftp://ipl.rpi.edu/pub/image/ and /image2/ converted from Sun Raster format to Windows Bitmap, (this conversion changes image headers only, 32 bytes are replaced by 54 bytes, but image data is not modified) and some of them were slightly renamed. 6,7,8 image sets are from ftp://download1.intel.com/pressroom/images/ 10th set was taken from ftp://ftp.kodak.com/www/images/dental/ and converted from TIFF format to Windows Bitmap.

1) In this release,everything was retested on a Pentium-200mmx PC with 32M RAM.
   This amount turned out to be enough to test Rkive 1.90b1 with "-mtx" switch
   (maximum compression mode) but not enough to run UFA32 with "-m5 -mu32".
   Not 8 but 10 (ten) sets of images in this release!
   Some bad news also: ESP 1.92 (release) has some bugs and was unable to
   correctly uncompress some test images: they are (re)named in our tests as
   AYMAR,GELSNGER,NACHTSHM,OTELLINI,VADASZ,YU1,DP081897,L217C-34,PS091597.
   ESP doesn't even report something like "CRC fails"...As if everything is OK.
2) Yes, we are going to continue this tests, even after ERI is no longer taking
   lead in the Art of lossless image compression (on natural True Color images)
   We now have about 200 images downloadable from internet, totalling 400Mb+
   and some knowledge how to test programs (and format results)
   automatically via batch files (all but CompuShow - no command line mode).
3) If you want to add ERI format support to your software or hardware products-
   just let us know!  It won't cost you a cent,
   you'll receive an algorithm and sources with support - for free!
        You needn't even mention that you are using
        "ERI compression algorithm for True Color images (c)1991-98 RAO Inc.",
        "2d-eri-ppm" for short,
        in your product.
   Absolutely nothing except that you'll be listed as "2d-eri-ppm algo users".
   Don't forget that this "2d-eri-ppm" algorithm was successfully tested
   by thousands of people all over the world during last four months.
4) No, neither ARI nor ERI nor Bmp2Eri did never use any patented (arithmetic
   coding, LZW, etc.) nor public domain algorithms (deflate, freeze, png...)
   If you are tired of conflicting some patents from time to time, note that
   Bmp2Eri doesn't use nothing even close to that arith,lzw,deflate,png,etc.


[[5]] PLEASE read THIS before replying to this article!

(1) Millions of thanks for your suggestions and attension! Since the first release of this test we have received hundreds positive replies by E-mail. While the only three negative responses were posted to newsgroops! (If you don't remember, they were: from Harald Feldmann, author of HAP, to comp.compression from Andrey I. Savov, a compression theorist, to comp.compression from Horst Hackenbruch, a BBS sysop, to comp.compression.research You can still find them, at www.dejanews.com for example.)
That's why, if you want to tell us something like this:
> P.s. I filter anything coming from hotmail as unwanted spam.
> the original poster doesn't really know what he's doing anyway.
> direct know what is happend... - an total unusefull nonsens not more or less.
> you are unable to correct many reported simpel errors at this ARI "program"
> over a long time. As excample "FCBS".
please don't post such "news" to a newsgroop, send them to us by E-mail.
If you hate hotmail, or don't like hotmail users,
or simply don't like what doesn't bring you (or your groop)
money or pleasure (now or later), most probably without even
noticing that as usual (n0! of course that's n0t about you),
please don't give such thoughts a tongue. Try to process them inside.
(2) The second reason why we ask you not to post negative responses
    to newsgroop(s) is that we shall not answer ANY replies
    by other way than E-mail.
Unfortunately we don't have much time to read and/or reply articles:
some of us don't speak english, many others are free away from any
networking stuff, even now, when we receive so many e-mails every day.
So, whatever you say about our tests in a newsgroop, we shall nOt answer
there, only by E-mail.
(3) Please don't feel angry, ignored or offended if you won't receive
any reply from us to your E-mail. We are really sorry, but we don't
have enough time to carefully read and answer all incoming E-mails.
Currently only two men can reply you (never more than three),
but only one, Alexander, usually does.

Send your suggestions, comments to ratush@srsc-gw.sscc.ru
        (the old addresses Raoinc@hotmail.com and ras@okibox.iae.nsk.su
        are still valid but are checked not too often)
With best kind regards,
RAO Inc.
P.S.
Once again:
PLEASE!  if you are going to answer this article,
find the above mentioned replies and re-read them
to understand what we are writing about,
what "news" we ask you not to post.
