[ALLY] Amiga setup tip

 [1/12] from: steve:shireman:maxonusa at: 7-Aug-2000 11:36


I searched the list to see if anyone had mentioned this, but I had hit some trouble getting my A3000 to run Rebol/View. (EGS chipset) At first I thought it needed more memory. However, the problem I had was that my screen was too low of a resolution for the demo window size. So there are two work arounds at least: Make a user.r which has demo: off or What I did was make a big virtual screen of my same resolution, and that gave enough pixels for the demo to run, which was then bigger than my monitor. Just call me a lores guy. (Or maybe I just want my RebTV!) So has anyone got a way to show ILBM or picture datatypes? jpegs had a nice fast decode... Steve Shireman

Ah, ha! Most of the programs I run are mine, on a 4000. I had not attempted to run the demo on the A3K because I was told that the minimum colours were 256. Although I can see reasonable colours with my default 8, 16 colours is nicer. I won't be running the demo very often, but now I know better what it takes to get some colours working.

I am using the A3K's VGA port, so my res is not too low.

To start, I doubled the width & height, but I use PAL, so all I really needed to do was make the screen taller.

Use what you have... it seems to work. -- ---===///||| Donald Dalley |||\\\===--- The World of AmiBroker Support http://webhome.idirect.com/~ddalley UIN/ICQ#: 65203020

Yes, the console locked up when hitting the close gadget, which I had submitted as a bug report this last weekend. That was 0.9.9 or whatever that Beta version was. This morning before work, I just installed the Developer version which is later, but I haven't gone back to see if that problem is already fixed or not. As far as ILBM's, I do think they would provide lots of existing content for all platforms, to have that reader there, and give Rebol a great big edge over Java, for the graphics that could be used. (It takes time to develop new artwork! And I have tons of great GUI artwork in ILBM form) Of course, a converter could be written in Rebol, although I think the .jpeg decoder is written in asm for speed if I remember info from the past correctly. (have you ever tried to look at an ILBM with netscape? the poor thing gets cornfused with such standardized IFF graphics...) I suspect since most ILBM's (ANIMs would be nice too!) are inherently compressed but do not require a fat processor to use efficiently, that they could give excellent speed results. Anyway, thats my $.02 from the soapbox. Steve Shireman Every picture tells a story, don't it? Rod Stewart [carl--cybercraft--co--nz] wrote:

Yeah, I noticed that is done automatically by the system when you hit the demo on/off button. I thought it was a mistake, so I changed mine on the Weinie95 Machine to demo: off and that seemed to actually work. Of course, my registry Monkey has run amuck, so I have to sort out which directory is actually running. I have Rebol installed in about 4-5 different places, so I better verify before I report anything. Steve Shireman My real computer is an Amiga. [ddalley--idirect--com] wrote:

I hit they same problem when I tested View on a default Workbench settup. The Demo's Welcome window requires a screen of about 680x540 (just checked) while some of the View examples in the REBOL library may require anything up to 1024x768. When you try to open a REBOL window that's too large for your screen, does your Amiga lock-up when you try to quit the console? That's what I get on my Workbench3.0 A1200.

You're on your own with that I think, as support for system-specific features such as Amiga datatypes isn't really the REBOL way. You'll need to convert your ILBMs to GIFs (or perhaps JPGs if they're greater than 256 colours) before you can have View display them. Carl Read.

Nazdarek [steve--shireman--maxonusa--com] After reading messages regarding Amiga sutup tip I've diced to write some comments: 1. ILBM - I DO NOT WANT ILBM - old and limited formad but I wonder why /VIEW does NOT support PNG? There are some licence problems with GIF - so PNG was introduced with NO legal restrictions - this looks more like what I think of like 'REBOL philosophy' . 2. AMIGA SETUP TIP - put in your %user.r this lines: system/view/screen-face/options: [ exclusive-colors: true ; REBOL on own screen dither: true ; turns on dithering monochrome: true ; REBOL in b/w ] RT think that REBOL checks for true/false value but it checks only if word exists so put in your %user.r only the words you want to set (e.g.: do not put monochrome: true (or monochrome: false) in your %user.r if you do not want to see REBOL only in shades of grey.

Surely the more file formats that can be read the better? Some kind of universal loader like the one Wolf Faust wrote for PageStream would be ideal. This would be too big to include in the View executable, though. Although ILBM is limited, there's no reason why IFF can't support all the features of PNG. It is an open-ended format, well designed for parsing. It is more or less a binary equivalent of XML, as the chunks can be nested. Regards -- Don Cox [doncox--enterprise--net]

Well, good (sortof) to hear it's not just my Amiga that does it. (I'd reported this bug a while back as well.)

It wasn't fixed in the Amiga Experimental View release 0.10.18.1.1 released, hmm, three or so weeks ago now. Might've been updated since then...

Why can't you just convert your ILBMs to GIFs if you want to use them with REBOL? JPGs and GIFs are the two most common image formats on the Web by a /long/ margin. Adding native support for other image formats, (and there's plenty of others besides ILBM), will just increase the size of View to no great purpose. (Though there's a good case for adding PNG support so REBOL has loss-less 24bit support.) That said, scripts written to load and save different file formats are a different matter and do make sense. I've not absorbed what REBOL-modules are yet, but perhaps they'd be the ideal way to add such support?

They're fast compared to JPGs and GIFs, but then they aren't compressed as much, which is important on the Net. (Those with decent computers just ignore this discussion about image speeds, okay?:) Then REBOL has its own native format, hasn't it? Anyone care to comment on how it compares, compression-wise? (Assuming I'm right that it exists, of course.:)

(Assuming I'm right that it exists, of c> course.:) It isn't compressed, but you can compress it with COMPRESS; it uses the same compression algorithm used in PNG (AFAIK), so... But REBOL supports 24 bits only. Anyway, REBOL is able to load 24 bit BMPs, so there's at least one lossless 24 bit format available; nevertheless, I agree that PNG should be supported.

PNG is not as general as IFF (which was created to contain ANY kind of file), but is quite good as image format (surely better than ILBM, that was created with the Amiga chipset in mind).

Thank you Boleslav for posting this! I wanted View on its own screen from the start but didn't know there was support for it. Much appreciated. My screen and window bars are black in 16bit though, and I can't see the window close gadget. (Different coloured bars on different screen depths, but still no visable close gadget.) Anyone else getting this with Amiga screens? Carl Read.
