The Art of lossless image compression, 3rd release. Here are the results of 8 (eight) tests performed to compare lossless compression of True Color (24-bit) images by some general purpose archivers: ERI32 3.0c4, 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. If anybody wants to start or continue such tests, 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!

Files for last three tests are from ftp://download1.intel.com/pressroom/images/ and converted from TIFF format to Windows Bitmap. The "+" symbol shows absolutely best result; "." indicates relatively best result; "`" means you see here not "RAR -m5-mm" but better "RAR -m5-mmF" result.

Since the first release of this test we have received many positive replies by E-mail. While the only two negative responses were posted to newsgroops! (If you don't remember, they were: from Harald Feldmann, author of HAP, 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. or like this: > 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 (nO! of course that's nOt 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
