#20668- RGB to HSV Message #20994
From: Kevin Northover Forum unknown · C Programming March 1, 1992 3:53 PM
There is code to do this in Graphic Gems, vol 1. I don't have it handy at the moment but it shouldn't be too hard to locate. – kevin

#15593 AppShell Message #15617
From: Kevin Northover Amiga Tech Forum · Developers October 16, 1991 8:18 PM
Steve, I did mean the 1990 disks, I don't have the 1991 materials yet though I intend to get them when they're available to people who didn't get to devcon. I hadn't realised that it would be (i) licensed or (ii) so closely tied to Appbuilder. I figured that I…
AppShell Message #15574
From: Kevin Northover Amiga Tech Forum · Developers October 15, 1991 9:41 PM
Has anybody had any luck using the appshell.lib from the 1990 devcon disks with Aztec C 5.0d. The linker doesn't seem to recognise file as an amiga object file. Manx's adump utility reports: "Got funny code 3fa @ 0" A Type OPT H of the file has the first three…
#21223- #What's the latest Ver? Message #21481
From: Kevin Northover Amiga Vendor Forum · Avant-Garde February 11, 1991 10:31 PM
I've always thought that by constructing an amiga library and using the INLINE feature of M2Sprint it should be relatively easy to interface to other languages. You do need to know the offsets for the library jump table but if you build the library yourself that's no problem. So no…
#2774 Where's Manx??? Message #2838
From: Kevin Northover Amiga Tech Forum · C Programming October 30, 1990 9:06 PM
It is a 201 number, New Jersey not 203. I haven't checked their bulltin board for a week or so but they hadn't replied to a bug report last time I looked Kevin
#Image Compression Message #1300
From: Kevin Northover Amiga Tech Forum · Developers September 30, 1990 9:33 PM
Vic, Ariel Thanks for your replies. There is an interesting recent paper on fast compression algorithms with very fast (~1 sec) decompression in the Proceedings of the 1990 International Conference on Pattern Recognition. IEEE publish these. The paper is: "Hierarchical Visual Pattern Image Coding" Dapang Chen and Alan C. Bovik…
#1245 IFF Chunky Pixel Message #1295
From: Kevin Northover Amiga Tech Forum · Developers September 30, 1990 8:36 PM
I know of the chipset. For my application I can do compression much faster than JPEG with probably comparable image quality at the same compression. My client wants software, the incremental hardware cost hurts his marketing (he says). But I'm very specialised. The new NeXT machine graphics board includes the…
#1170 IFF Chunky Pixel Message #1294
From: Kevin Northover Amiga Tech Forum · Developers September 30, 1990 8:32 PM
I've read the general publications on Barnsleys methods. I'm not impressed. The encoding computation costs are horrendous (and fingerprint archives are huge, small systems are >300,000 images). Second he seems to require human intervention to encode. I can't accept that. As for JPEG the most recent suggestion I saw (in…
#IFF Chunky Pixel Message #1144
From: Kevin Northover Amiga Tech Forum · Developers September 26, 1990 10:00 PM
I recently registered as a developer with CATS. I use the Amiga to develop image processing and matching software, mainly for automatic fingerprint recognition. At the moment I have a very ad hoc collection of program harnesses used for developing compression algorithms. I want to rationalise these, at the moment…
M2Sprint and 2.0 Message #17880
From: Kevin Northover Amiga Vendor Forum · Softwood July 21, 1990 7:24 PM
A short note for anybody interested. M2Sprint works well under 2.0 on a 3000. Compiles, links, programs run (as one would hope). I haven't tried running from the F3 key yet as I never do that anyway. It is very fast. The only glitch that I have found so far…
#17342 More on (long)reals Message #17457
From: Kevin Northover Amiga Vendor Forum · Softwood June 22, 1990 9:41 PM
1 I totally agree with everything you say. It is exactly my own assessment of Leon's conduct in this forum over the past few months. Kevin
#17253- More on (long)reals Message #17456
From: Kevin Northover Amiga Vendor Forum · Softwood June 22, 1990 9:37 PM
Leon Your remark about those not interested in using M2Sprint coming out with fairy tales and whining on Compuserve is both offensive and untrue. We have admittedly crossed on CIS earlier this year. I am very interested in using this package, you currently have a specific bug report and a…
#107458- #Dynamic Arrays Message #107689
From: Kevin Northover AmigaTech Forum · C Programming June 4, 1990 9:22 PM
I've just uploaded dynamem.zoo to the library. You will need the DBUG macro package from the Fish disks to compile it, otherwise just do the obvious edits to remove the debugging macros, there are only a few lines affected. The package is very reliable, I have used it on Amigas,…
#105046 Avant-Garde & M2S Message #105197
From: Kevin Northover AmigaTech Forum · Other Languages May 17, 1990 6:55 PM
Harry, I think you have the latest version. The release was called 1.10, the editor shows 1.11 in its "About " panel. Apparently upgrades were called 1.11 and New Sale packages 1.12 for some administrative reason. An improved (and faster) debugger called 1.12 was later uploaded to the library in…
#16778 M2S and 2.0 Message #16829
From: Kevin Northover Amiga Vendor Forum · Softwood May 17, 1990 6:50 PM
Robert, Please advise Martin NOT to use ARP again. It broke partially between 1.2 and 1.3 (some of the commands) and now again, seriously, between 1.3 and 2.0. However nice it was there is no excuse for that, CA have always made the rules clear. I only use it for…
#16751 M2S and 2.0 Message #16769
From: Kevin Northover Amiga Vendor Forum · Softwood May 14, 1990 9:21 PM
Thanks for the reassurance. I knew the editor didn't use the ARP file requestor, I just had a nagging memory of something about the regular expression code used on start. One can say m2a xxx#?.mod and so on.
#103453 SAS Rumor Message #104093
On the plus side for SAS. It is a big complex package. It is also enormously powerful. One of my staff has just done a massive and very sophisticated R&D job with it. It cut months of our development time (on Sun-3s and Sun-4s). If you need something like SAS…
M2S and 2.0 Message #16690
From: Kevin Northover Amiga Vendor Forum · Softwood May 11, 1990 9:23 PM
Sylvain, you mentioned the ARP stuff breaks in 2.0. I never use it but the M2S editor does. Do you know if that will break. It matters, my 3000 is on order! Kevin
#102119 #Dubuggers? Why? Message #102171
From: Kevin Northover AmigaTech Forum · C Programming May 3, 1990 8:19 PM
I'm really trying to stop this languages debate, not fan it. The following (1960) quote from S. Gill, one of the early pioneers of automatic programming really summarizes my views on the whole subject. "If computers had existed in the Middle Ages, programmers would have been burned at the stake…
#101844- Dubuggers? Why? Message #102169
From: Kevin Northover AmigaTech Forum · C Programming May 3, 1990 8:14 PM
I agree, I like strongly typed languages, that is why I prefer to develop in M2. I think the compiler should do the checking for me. I might move to rexx for prototyping, as I do for small tools, because it is also quite stringent in its checking.
#16569 M2S Support Message #16573
From: Kevin Northover Amiga Vendor Forum · Softwood May 3, 1990 8:09 PM
Leon, Thank you for that reply to Wayne, he obviously expressed himself more clearly than I did. That information, including the contact address, is really all I needed at this point.
#101606- Dubuggers? Why? Message #101613
From: Kevin Northover AmigaTech Forum · C Programming May 1, 1990 9:15 PM
personally I prefer interpretative debuggers. Ever used Saber-C on a Sun? With the new generation machines I'm likely to prototype in Rexx then port for production for this reason. Right now I do prototyping and algorithm development in Modula-2 and port my release code, which has to go to a…
#'030 vs '040 Message #99949
From: Kevin Northover AmigaTech Forum · Hot News and Rumors April 25, 1990 7:55 PM
About the '030 vs 040. Note that the first generation 040 chips are 25Mhz. These should just drop into a 25 MHz system. The dead products are the >> 25 Mhz '030 systems, why do all that EXPENSIVE extra engineering when the next CPU doesn't need it. For my money…

#8768 M2S wish list Message #8809
From: Kevin Northover Amiga Vendor Forum · Softwood May 28, 1989 9:00 PM
I thought of that, I load M2E in my startup sequence. After that the only time I even need the M2Sprint_Tools disk is to load Compiler/Linker (first time used) or if I'm in the throes of debugging. I specifically don't want to keep reloading the environment. Kevin
#8757 M2S wish list Message #8808
From: Kevin Northover Amiga Vendor Forum · Softwood May 28, 1989 8:58 PM
Thanks, I'd only tried the implementation as stand-alone once, late at night so I may have overlooked something, I'll try again. On further thought about default tools I decided that I could live with I could live with M2Sprint: by pulling some more trickery with PathMan.
#8606 #M2S wish list Message #8754
From: Kevin Northover Amiga Vendor Forum · Softwood May 25, 1989 9:30 PM
I would prefer the default tool for editor files to be C:M2A. The whole point in the HOT mode is to get the editor loaded and then keep the small activator where you can get at it fast. In my case I keep M2A in RAD:C which is my C:.…
#Targa to Amiga? Message #12300
From: Kevin Northover Amiga Arts Forum · Videophile February 20, 1989 9:26 PM
I need a conversion program for Truevision TARGA images ( ICB and VDA ) formats either to ILBM or a straight display utility. I have some of these as test input data for some software of my own but currently have no code to reduce them from 32768/256 color respectively…

Thank you, it is obviously fixed now and is much faster tonight. Kevin
#slow response Message #1139
From: Kevin Northover AmigaTech Forum · Forum Business/Help July 18, 1988 10:05 PM
Why is the new forum structure so slow, I'm getting messages like files busy, or no response at all for a minute or more when I just try to move through the menus, it takes 30secs odd to respond to a go AmigaTech. I heven't attempted the other forums, I…
#133746- #TID compiler Message #133760
From: Kevin Northover The Amiga Forum · Modula-2 July 8, 1988 9:44 PM
Just to add my own comment, as I've posted a couple of times recently I too have been able to do what I want with the TDI compiler. Now that I have enough ram to keep the M2 modules in memory I am also impressed with the speed. It isn't…
#133411 porting to C Message #133431
From: Kevin Northover Forum unknown · Modula-2 July 5, 1988 8:34 PM
thanks for the note, I'd missed some of that stuff. However raw (integer in this case) CPU is not the only is, there are display issues too and a UK Government spec that runs to 100+ pages. The Amiga isn't really in that market yet at a credible, supportable level,…

From: Kevin Northover Adobe Forum · Programming February 21, 1988 9:33 PM
A question, has anyone found an elegant (and fast) method for converting the Amiga's bitplane format to a nice pixel per byte form for quantitative processing? My own shift and OR code is moderately fast for C and 68000 but I keep wondering about the PixMate "Hyper-Slice" technology …
source version control Message #110236
From: Kevin Northover Adobe Forum · Programming February 21, 1988 9:32 PM
Does anyone know of a source code version control package for the amiga? I'm not looking for SCCS or RCS but I would find something that kept track of a simple sequence of version numbers (1, 2, 3, …), dates, and comments very useful. Most of the bits are around,…
