Haven't visited Photobucket in months. There is some serious spammy

spyware installed and wanted me to download a program.

why not post/publish the images (or a composite) in this thread?

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

No dithering? Are you sure?

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'?).

That's fine! I will install DEV-CPP on my Windows 7 and compile yip for 
you! But be aware that its development is far from finished, and even 
some of the already implemented features are not fully functional yet!

Be aware though that Windows 7 is almost finished: January 2020. Is it 
worth the while? Better to make the effort for Widows 10, I guess...

I hated 8 and 8.1.   Not ever doing 10 if I can help it.
Really trying to transition over to Linux and open-source, non-proprietary
software.

Too much lying, spying, stealing, unwanted/unneeded auto-updates, data-mining,
etc.


Mike, have you tried IrfanView for conversion?
How about Paint.Net?

I don't have IrfanView installed, and Paint.net apparently requires a 
plugin to do animations. (I tried without the plugin and it only 
recognized the first frame.)

Hi there, I know this thread is over a year old but I recently needed to make an
animated .GIF. I also did some comparisons and found a combination of tools that
produced excellent results. Here's what I did:

1. Use IrfanView to reduce the images to 256 colors (no dithering, check the
"Use best color quality" box)

2. Use Photoshop to create the animated .GIF.

Using Photoshop to reduce the bit depth of the images produced surprisingly poor
results. I also tried Paint.net. On-line .GIF making utilities were even worse.
My final product is attached for comparison.

IrfanView is also a great tool to compare animated .GIFs because it can play
them magnified.

Mike, if you don't have Photoshop and you'd like to give it a try let me know
and I'll make the .GIF for you.

Have a great day!

Kind regards,
Dave Blandston
