yeah I saw it but, I'm not gonna lie, I think it took a beating, it's one of those that probably can't be converted properly (maybe)

Yes, some colors got dropped.

 

It might be down to analyzing the 35 color interlaced palette generated from the color settings used here.  A better render might be possible.

 

All this is, is a blending of two G2Fs, one Antic 4, one GTIA 10, which share the same BAK and PF0-PF3 color settings.  It is by no means optimal, sadly.

You're not making any sense... all the pics labelled as multicolor are 16 colors. You can download the prg for most of them and run it on a real machine.

 

Screenshots were taken on emulators and may have some effects applied to them which would bump up the number of colors

 

Your conclusion doesn't make sense ;)

1. The images don't show the real thing.

2. You need to buy a C64 to see the real stuff

3. If you don't have the real thing , you'd have to believe what the computer shows to you.

4. Wow: C64 had 28 colors and 16 different lumas.

 

 Conclusion: C64 was better than written in the books. If the real thing doesn't exist, you cannot check the facts and have to believe your available sources.  They are everywhere, so they might be correct ;)

 

Luckily there are sources, showing the real images, banishing a lot of those flying unicorns.   

It helps to analyze the image , and to think of solutions ...

Looks good.

 

Do you have enough resources available to mask the sides with black P/M's? Then you can just make the top and bottom strip black with playfield and it'd all look more polished.

A bit of progress...

Not sure how you built this exactly. 

But the dli colored border destroys the image. 

The picture is rather low on colors per scanline. It's 5 to 7. So a unicolor border (dark grey ?) really should be possible.

What Program is saving 8 bit per pixel pngs? 

The Gimp can do it, too. Image->Mode->Indexed and then export as PNG. If your source has <=256 colours, it's lossless.

How about Yoda in blue or even some more realistic  saffron?

Thanks, regarding masking with PM, it may be possible for this picture but most of the time it's too big a compromise...

Well you know the limitations... I'll probably have it as an option though.

 

(I prefer it looking untidy on the border rather than inside)

Rasta Juice, without PMG, only bitmap mode and raster split

 

I don't know what Yoda's been up to but he's got green goo in his hair.

Rasta Juice is a tool to convert images to G2F without much time consumption. 

On the other hand it points 100% to the limits of raster programming in mode e.

Threads like this one also point to some "not so unrelevant" part of the graphics department. 

The color mixing, pixrl dither, or even transition painting, needs to be different on the Atari. It is possible to adopt images from the C64 palette to the Atari palette, but the pixels on the C64 were more to create spare part colors. 

Removing the "spare part color pixels" solves some color usage problem, as the Atari could bring the more correct color. 

Only when pixels were used to show details, they need to be adopted 1:1 . 

Not so easy to find a software based filter for that, I guess.

sure dithering creates extra colors on the C64 but it also gives extra details and fuziness so removing it isn't always the solution.

 A bit more progress...

 

@superrune's famous Bruce Lee pic, one of my favourites which made me get in touch with him for PoP

 

This one is complicated and took a me a good few hours... it's mostly a success but the yellow bars are a problem 😕

Many glitches but at least Bruce is mostly good.

I did a hand recoloring to have less errors in the picture...

In the coloring of the lower hand, you see that Mode 4 is stronlgy recommended for that, to have clean images.

...pretty popular picture it seems!

On March 2019 I tried with Rastaconverter.

Unfortunately the result wasn't perfect.

yeah it just zapped 2 out of 5 body colors... pretty decent result nonetheless

nice... the changes are subtle... My purpose wasn't to get this specific picture on the A8 at any cost though but rather push that tool to see what I can get while staying as close as possible to the original.

I know. 

But have a look from that point. 

Changing the colors , to have the picture looking better with the atari's pallette , made it better for Rastaconverter to adopt the image. 

Sounds weird, but the color pre-processing allowed to have a closer result to the original.

Yes, even when the original is used:

 

Gotta say I much prefer Superrune's version...

 

 

Anyway, here's a bit of an update... still trying to do some color reduction without altering the quality too much.
