What you mean? What source and what properties of this image? Is that true, that each tile uses only one palette?

Why you asking? You know all about this pic, it even was made in your program.
Of course it 1-layer, each tile use only it's row.

[r57shell]

I just thought that it's some image better than output of my program. Because, I tried to see output with 60 colors = 4 rows, and output was different.

Oh, sorry. You're right. I looked at it again and did not see this. The images are quite different (worse, I'd say) with this bug corrected. I'll do some tests to see what to do (to transform the bug into a feature or to correct it and change other things).

(Maybe we should talk about my script in the topic dedicated to ImageMagick in order not to hijack sega16's thread too much)

I have a slightly better image with additional layer to this pic. (color count same, just for remove artifacts)

scolorq lab 15 genesis colors. I think, it's impossible by hands :S

scolorq lab 15 genesis colors. I think, it's impossible by hands :S

Now I see, it's look much good, than RetroGfx output. ([s]retro loses green color of grass[/s]).
2) it can't make 4 rows for this pics (makes only 3), and increase of color count will not add green.

I will try your and Frederic utilities.

oh. It was only in old version. New version actually no lose green.
RetroGFX 16 colors with dither

[r57shell]

scolorq does not support tiles depended palettes. I mean, any tile can use any color.

I tried to convert the image using my method:

4 palettes, 40 colors, R3G3B3

[r57shell]

Good result. What is your method? I see ordered dithering.

[Orion_]

I use Ximagic plugin to convert the colors to 9bits (RGB333)
http://www.ximagic.com/cd_index.html
There are plenty of configuration to change the dithering pattern.
Then I use a professional tool to generate the 4 palettes and tile repartition. (can't post this one sorry)

[r57shell]

Interesting way. I will try ordered dithering.

Even name?

I have just added support for scolorq and now am using ciede2000 for some nearest color calculations (slows down dithering but increase quality by abit)
The image on the left is the dithered image that scolorq outputs. The image on the right uses the same palette but is dithered with the standard floyd stienberg algorithm.

I also updated the windows binary and the source code as usual the links are the same.

For what reason you can't post this? Don't want?
Image looks very good!
Can you make this image with palettes to see how colors are sorted, or make a test ROM?

[r57shell]

I tried to convert the image using my method:

First of all, palette not MD.
Ok, now same way but with ImageMagick
From left to right: original, Orion_ version, Orion_ version in MD pal, ImageMagick two versions made by me.
