RIX's files with the extension  .sci and .scf are just a RAW file with a 256 color palette. The first 10 bytes is a kind of header, with the name RIX among 7bytes unknown stuff.

No.  That's *not* what I was complaining about, nor did I intend to suggest that DEC was any better than SGI (let me tell you about the Lynx some day, but be prepared with a large sedative if you do...).  My comment regarding DEC was to indicate that I might be open to other vendors that supported OpenGL, rather than deal further with SGI.  What I *am* annoyed about is the fact that we were led to believe that we *would* be able to upgrade to a multiprocessor version of the Crimson without the assistance of a fork lift truck.  I'm also annoyed about being sold *several* Personal IRISes at a previous site on the understanding *that* architecture would be around for a while, rather than being flushed.  Now I understand that SGI is responsible to its investors and has to keep showing a positive quarterly bottom line (odd that I found myself pressured on at least two occasions to get the business on the books just before the end of the quarter), but I'm just a little tired of getting boned in the process.  Maybe it's because my lab buys SGIs in onesies and twosies, so we aren't entitled to a "peek under the covers" as the Big Kids (NASA, for instance) are.  This lab, and I suspect that a lot of other labs and organizations, doesn't have a load of money to spend on computers every year, so we can't be out buying new systems on a regular basis. The boxes that we buy now will have to last us pretty much through the entire grant period of five years and, in some case, beyond.  That means that I need to buy the best piece of equipment that I can when I have the money, not some product that was built, to paraphrase one previous poster's words, 'to fill a niche' to compete with some other vendor.  I'm going to be looking at this box for the next five years. And every time I look at it, I'm going to think about SGI and how I could have better spent my money (actually *your* money, since we're supported almost entirely by Federal tax dollars).  Now you'll have to pardon me while I go off and hiss and fume in a corner somewhere and think dark, libelous thoughts.  							spl

Our shop uses a package called CADCore - very good - to scan and subsequently vectorize original maps into digital maps. The problem is that once the raster file is loaded into the CADCore package, a header is added to the .HRF file which makes it unreadable by the supplied converter. We would like to be able to ship some of the already-altered raster images for further use on our workstations. So, here are my questions:   (1) What is the Hitachi format? - I need this format so I can recognize precisely what to strip out. I strongly suspect that it's a compressed format - if so, then t might not be possible for me to strip out the offending header.   (2) Are there any UNIX packages that read and recognize HRF? It would be really nice to find some sort of "hrftopbm" converter out there. ;)

Hi all, I am looking into methods I can use to turn my Linux based BBS into a full color Graphical BBS that supports PC, Mac, Linux, and Amiga callers.  Originally I was inspired by the NAPLPS graphics standard (a summary of  which hit this group about 2 weeks ago).  Following up on software availability of NAPLPS supporting software I find that most terminal programs are commercial the only resonable shareware one being PP3 which runs soley on MSDOS machines leaving Mac and Amiga users to buy full commercial software if they want to try out the BBS (I know I wouldn't)  Next most interesting possibility is to port MGR to PC, Mac, Amiga. I know there is an old version of a Mac port on bellcore.com that doesn't work under System 7 But I can't seem to find the source anywhere to see if I can patch it.  Is there a color version of MGR for Linux?  I know there was an alpha version of the libs out last year but I misplaced it.  Does anyone on this group know if MGR as been ported to PC or Amiga ? I can't seem to send a message to the MGR channel without it bouncing.  Does anyone have any other suggestions for a Linux based GUI BBS ?

The gl2p1.lzh stuff under gfx/show on the Aminet sites includes a     utility called pic2hl, that is a filter for HamLab that can handle     the most commonly used kinds of .PIC and .CLP files.      The biggest problem is that the .CLP files don't usually contain a     palette, so you need to convert a .PIC with the right palette     first (which creates a "ram:picpal" file), and then convert the     .CLP files.  > Jacques Oberto  <oberto@genes.icgeb.trieste.it>

How can one dump to the printer, the content of a VGA screen. If it were a text screen, we can execute a shift printscr. but with graphics, we have to do a pixed by pixel print.

We want to be able to support DOS, UNIX, MAC, WINDOWS, NT, OS/2 platforms.  It is our hope that individuals, developers, corporations, Universities, R & D labs would join in in supporting such an endeavor.  This would be a NOT_FOR_PROFIT group with bylaws and charter.

Yeah, and it's also true most long complicated sequences of events, calculations, or big computer programs in general.  I don't argue that you can get similar and maybe useful results from fractals, I just question whether you >should<.  The fractal fiends seem to be saying that any part of a system that we can't model should be replaced with a random number generator.  That has been useful, for instance, in making data more palatable to human perception or for torture testing the rest of the system, but I don't think it has much to do with fractals, and I certainly would rather that the model be improved in a more explicable manner.  I guess I just haven't seen all these earth-shaking fractal models that explain and correlate to the universe as it actually exists.  I really hope I do, but I'm not holding my self-similar breath.  > There is one other thing that fractals are good for:  fractal > image compression.  Uh huh.  I'll believe it when I see it.  I've been chasing fractal compression for a few years, and I still don't believe in it.  If it's so great, how come we don't see it competing with JPEG?  'Cause it can't, I'll wager.  Actually, I have wagered, I quit trying to make fractal compression work- and I was trying- because I don't think it's a reasonable alternative to other techniques.  It is neat, though. :-)  I'll reiterate my disbelief that everything is fractal.  That's why I don't think fractal compression as it is widely explained is practical.  I know Barnsley and Sloan have some tricks up their sleeves that make their demos work, but I don't see anyone using it in a real product.  It's been six years since Iterated Systems was formed, right?  	"There are always going to be questions until there's a product 	out there," Sloan replies.  The company plans to ship its first 	encoding devices in the summer, he says.  In March, Iterated 	Systems will have the other half of the system: the decoders.  		- Scientific American, March 1990, page 77

Hi:  I am digitizing a NTSC signal and displaying on a PC video monitor. It is known that the display response of tubes is non-linear and is sometimes said to follow Gamma-Law. I am not certain if these non-linearities are "Gamma-corrected" before encoding NTSC signals or if the TV display is supposed to correct this.   Also, if  256 grey levels, for example, are coded in a C program do these intensity levels appear with linear brightness on a PC monitor? In other words does PC monitor display circuitry correct for "gamma errrors"?   Your response is much appreciated.   Amjad.
