>256 colors with Indivision for A1200?

[Piru]

The notion of a 15 bit RTG display running at 1024x768 on AGA makes me smile.

It wouldn't be that high resolution.

[Karlos]

It wouldn't be that high resolution.

Well, no, it wouldn't. It would be 6 or 8 bitplane HAM 1024x768 on AGA. The 15/16-bit BitMap would only actually exist in FastRAM, in theory.

DPaint 4.5 AGA with Indivision rocks!

"24 Bit colour resolution in all screenmodes" doesn't mean that it supports 24bit modes. It means it supports 8bits per gun (R, G and B).

Misleading? Perhaps.

The only way to get more than 256 colours with this setup is to use HAM6 or HAM8 screenmodes.

I guess I misinterperted that. I can get resonable color depth on my A2000 with Flicker Fixer, Picasso II, And Picasso96.

I take it Picasso96 doesn't work with the Indivision?

I was playing with ImageStudio last night. I didn't see any HAM options in the screen modes.

The attached pic is a screen dump from ImageStudio on my A2000.

It won't work. Indivision AGA isn't a graphics card.

I still think the marketing should be more clear about this. I am not so sure if you're the only one fooled by that "24 bit" clause.

Perhaps. I think the reason they state this is to distinguish their product from competitor's devices, some of which have had poor gun precision. In particular, I have seen some very strange arrangements as R8 G4 B4, which although fine for OCS/ECS are pretty poor on AGA. Thus their claim to support 24-bit colour is fine but they should be clearer about what they mean by that.

Scandoublers that don't support 24 bits produce incorrect colors in ALL AGA modes.

Even if you have a 16 color workbench on your A1200, the 24-bit precision is constantly being used to show the correct 16 colors all the time.

TN LCDs can make AGA look pretty nasty, too. Very noticeable with a good AGA slideshow.

Up unitl the Indivision: There was the commodore FF and others. The flicker fixer from Commodore but limited you to a palatte of 4096 colors, no 24bit

Then 16 Bit support was common after commodores demise with 3rd parts solutions.

The Invidision uses a 24 bit color chip to support a 24 bit pallete. There's no way for this thing to behave as a graphics card, where you get extra colors  in a 256 screnmode and nigher resolutions. It just promotes every native AGA screen to VGA scanrates and removes the annoying flicker.

I uses it with NTSC modes  as they run quicker. The AMiga is only generating 15lkhz signal. The Inidivusion promotes this to 31klhz. Using a DBLNTSC wit the Indivision is slow.

A really great product!

and nigher resolutions

Indivision is the only scandoubler which supports the HighGfx monitor driver which allows to use resolutions of 1024x768. So effectively the Indivision *does* allow to use higher resolutions.

Using a DBLNTSC wit the Indivision is slow.

For DblNTSC you don't need the Indivision. This mode can be displayed on a PC monitor without a scandoubler. And it is always slow, with or without the Indivision.

So would I need something like a Mediator and PCI graphics card to get 24 bit color on the A1200?

What advantages do AGA offer?

For what you are trying to do, paint and desktop publish in 16 million colors then the answer is yes.  That is how I do it btw.

What advantages do AGA offer?

You already have AGA so its main advantage is that it is free.

If you add a mediator + PCI gfx card then you still have your AGA gfx modes.  But in addition you have PC gfx modes.

@Karlos

2 great paint programs already do that, TrueBrilliance and DPaintV. Never tried the later but the 1st can use an internal 24bit buffer. TrueBrilliance works like this: If you draw for example a white line over a 24bit image it gets drawn with normal HAM8 and so is displayed with artifacts. This is while you're drawing and keep the mouse buttom pressed. As soon as you release the mouse button the program seems to analise what you've just drawn and the HAM8 artifacts (or HAM6) gradually (and pretty fast but you can see it) disappear. It seems to be be either calculating a new pallete to cover the HAM artifacts or, even better, using the copper to change it on the fly. Many years ago I also wanted to know if it used the copper or not (probably would need to disassemble the copper instructions for a modified and a premodified image and compare them) but never bothered...

This is starting to seem like the old discussions I used to see here back in the old times:)

I've always found that an interlaced screen at the same res and colors is faster than a native dblscan or productivity.  I'm assuming then using the de-interlacing function of the indivision will in practice therefore give you faster display at the same res and color depth and refresh rate

I have the Indivision for my A1200 and I don't see any options for more than 256 colors... I only want more than 256 colors for paint and image applications, not Workbench.... I have a accelerated A1200, with Apollo 1240 and 32 meg RAM.

How do I get screen modes with more than 256 colors?

You installs Indivision Screen Modes in Devs:Monitors?

[Piru]

No.

Lets try again:

1. Indivision AGA isn't a graphics card
2. Indivision AGA doesn't give you any more colours
3. Indivision AGA does not give you 15, 16 or 24-bit modes
