I really like these "AOC 3.6" sprites! How do I get them? I downloaded the latest version but only have command line and I don't see how I can get them? It's not a aic setting I think? This is because you certainly get v1.2.. AIC settings comes with the future >> v1.3 << version (beware this is is ...

This is because 1) it is fairly new 2) it is on another branch 3) it takes a very long time to generate.

I'd love to have the .TAP files for all of these images, so I can dig into the bytes in a debugger and see for myself how the bits are set, one by on.

You can get them by clicking on the pictures there.

Oh, I just want to avoid writing misleading infos in the README. You say "Using colors that are the same when inverted", which I interpret as c1+c2!=7. This might look restrictive since this doesn't lead to repeating consecutive lines. The first line allows colors (paper,ink) = (0,c1) and (7,c2) whi...

Am I right to say that as long as you just modify the ink on the first column, and only use the invert bit on other columns, this is AIC ? Then for the color tuple to use is another matter that doesn't really matter the "AIC" label. Colors 7,7 and 7,3 are as valid pairs as is 6,3 (here I mean ink1,i...

Paper is always black for AIC in my conversions (see above). When I write AIC=n,n I don't mean paper=inc=color #n, but odd line ink is color #n and even lines ink is color #n as well. So my question reduces to: can we tell that monochrome pictures are actually proper AIC ? Or should I stick to diffe...

I mean: does the word "alternating" imply that the colors in the pair MUST be different. Asking differently, is the pair 1,1 a valid AIC mode? Alternating between red and red seem strange to me. (This is just a vocabulary/philosophy issue indeed.)

Hmm I'm facing a philosophical issue. Is AIC=n,n a legit AIC mode ? I mean this is technically possible, but do Oric-users consider it as a legitimate couple of colors, or is this abusing the AIC definition ? BTW: couple 3,6 is very great. One does hardly produce bad AIC pictures with it from my tes...

Although I'm usally not a huge fan of AIC or dithering (nice on small screen captures, sometimes painful on larger screens), I have to say all this work is really amazing. You guys are really talented in finding all the possible best combinations of colours, and doing this so fast! I think AIC can ...

:shock: This looks really very good... So what exactly did you do here? If I can guess: he made a palette mixing 2 colors for the oric: 1+2, 1+3, 1+4, 1+5, 1+6, 1+7; 2+3, 2+4, 2+5, 2+6, 2+7; 3+4, 3+5, 3+6, 3+7; 4+5, 4+6, 4+7; 5+6, 5+7; 6+7 = 21 entries. He then map the original image to this palett...

I actually quite like the one called "maybe". What settings did you use to generate that one? It is generated by the next version in the pipe. That version will contain some nice enhancements An algorithm to generate "Ordered" dithered image on the ORIC (NEW!). This works with AIC and non AIC. A se...

I'm about to think that ordered dither might be better for AIC but ordered dithering with Oric constraints is something different.

Well...

There are more details, but the dither makes the whole thing looks a lot more "noisier". Sure! Error diffusion is just that: add noise to simulate missing color. I'm about to think that ordered dither might be better for AIC but ordered dithering with Oric constraints is something different. Anyway...

Am I right ?

Exactly!!! And additionally, is it possible to optionally specify those two colors (rather than let the software choose)?

If you chose the 2 colors, then the algorithm reduces to a plain dither.

I'll see what I can do on that topic. Stay tuned.

That's not actually a bad idea: Basically have the algorithm select the best combinations of ink, paper, invert, with a fixed set of color attributes on the left side of the screen. Try to press the "RUN" button on the GrafX2 launch dialog while pressing the "a" key on the keyboard with the latest ...
