Thanks for the hint! I remember playing with BoxTop's ProJPEG years ago, but missed out on ImageVice.
  • FYI: The settings for ImageVice are saved in IVPrefs.DAT which is created in the current working directory. Usually, that's the folder where the EXE of the host application resides.

I've checked the code, and previous 'adaptive' is now 'adaptive + floyd'

Thanks - but I don't see that option in the gui.

In the reduction to binary there is a "Binary (Floyd Steinberg)", and in the Image - "Convert to colours..." "Dithering - Floyd Steindberg" (which also seems to be spelt incorrectly).
These don't help in reducing file sizes because random dithering makes for very incompressible graphics.
Perhaps the Map - Posterize... is the option to try.

Some programs have separate options for color palette and dithering method. I think that's the way to go.

In xnview it's in image->map. It's a per-channel color reduction, but it's very coarse and unconfigurable. No dithering at all, no adaptive palettes. 18-bit is 6-bits per channel, which is labeled 64 in xnview.
