I converted the same PNG input files to GIF using various tools. Which 
version do you think looks the best? Also note the file size.

Haven't visited Photobucket in months. There is some serious spammy 
advertisement there now. One ad played loud audio that said I had 
spyware installed and wanted me to download a program.

There is a file size limit in effect on the newsgroup.

I'm trying to determine which tool produces the nicest looking output.

Sorry about the Photobucket links earlier. Here are the same images, but

No dithering? Are you sure?

Maybe a matter of personal taste...

So *this* is the non-dithered version!

I'm developing a command line-based image processor (yip - Yadgar's 
Image Processor), with color reduction and Floyd-Steinberg dithering 
already implemented. Do you want to try it? I could send you the source 
code...

See you in Khyberspace!

You're right! I got those two mixed up.

To avoid further confusion, the one with 3,929,691 bytes is my favorite. 
It was created using Jasc Animation Shop 3, which is something like 15 
years old, and still great! I uninstalled the program it came with (PSP 
9) but kept the GIF maker.

I forgot to post a link to the original 24 bit animation, so here it is:

https://drive.google.com/drive/u/0/folders/1Sp1_LiI0y8yMquVCEqF1yVIkIpFkQy07

You may need Google Chrome to view it. I couldn't get it to load in 
XnViewMP for instance.

I wouldn't know what to do with the source code sadly. But I would be 
willing to test a Windows executable.

what other features does 'yip' offer?  which libraries does it use (ie
dependencies)?

> Do you want to try it? I could send you the source code...

you could post a source archive here (or 'p.b.utilities'?).
