Compression of README GIFs

[gezeta-id]

Hi.

Some people were complaining about the images in the README taking a while to load or not even loading at all sometimes.

As a suggestion, you may want to consider compressing the GIFs.

In case you're interested, I've done a quick and dirty test and it brings the size from ~23MB to ~10MB which is a nice improvement without bringing down the quality too much.

If you want them, here are the compressed images:

I did see some comments about it. Thank you for taking the initiative to compress the GIFs! I'll update the README with your GIFs shortly :)

My pleasure. It's the least I could do )

Hi @gezeta-id!

I was checking your GIFs and I noticed that we can compress it even further. Because I still have the original videos, I converted them again to .gif, but this time I tried to optimize it for size:

• Downscaled from 485x368 to 270x205 (width is fixed by the README)
• Decreased FPS from 12 to 10
• Decrease quality from 100 to 70

These were the commands I used:

ffmpeg -i surfaceplot.apng -vf "fps=10,scale=270:-1:flags=lanczos" frames/frame_%04d.png
gifski -o surfaceplot.gif --fps 10 --quality 70 frames/frame_*.png

Before (~22.6MB)

• duckplot.gif – 4.3 MB
• lineplot.gif – 3.2 MB
• markerplot.gif – 1.6 MB
• scatterplot.gif – 2.8 MB
• sphereplot.gif – 5.6 MB
• surfaceplot.gif – 5.1 MB

After (~5.15MB ~4.4x smaller)

• duckplot_low.gif – 757 KB (5.7x smaller)
• lineplot_low.gif – 679 KB (4.7x smaller)
• markerplot_low.gif – 575 KB (2.8x smaller)
• scatterplot_low.gif – 639 KB (4.4x smaller)
• sphereplot_low.gif – 1.1 MB (5.1x smaller)
• surfaceplot_low.gif – 1.4 MB (3.6x smaller)

The GIFs were updated in the README in the commit 0fd0651!

Thank you for helping improve ImPlot3D, @gezeta-id! Feel free to check out the discussions if you're interested in contributing to new features 🙂

That's great! Much, much better than my attempt :)

Happy to see it loading so fast in the readme now.
