What tool is Imgbot using to achieve its results?

[K0-RR]

Is it optipng, imagemagick or sth else?

It is Magick.NET (https://github.com/dlemstra/Magick.NET) that has it's own code and some ImageMagick code to optimize the files.

I have no experience with ImageMagick or your .NET library but I have some with Oxipng and it seems to always be better than Imgbot. I can tell you more about this tool and link some PRs - Imgbot ones and mine with Oxipng for the same files so you can compare.

If you are not interested / don't see a way to make use of this tool in Imgbot then just close this issue.

For PNG compression it might be a good idea to search for an alternative. Feel free to research this.

I did some tests and then forgot about this. A few days ago I discovered another tool - https://github.com/JayXon/Leanify and it seems to outperform anything else.
Running more tests and will post results later.

The problem is - leanify optimizes many formats but there is no option to exclude some of them so if it sees JSON or xml files it makes them hard to read - minified.

Unless someone PRs a "fix" to Leanify the only way to use it for image-only optimization is to make a copy of the repo first, run leanify on the copy, and then move all image files to the original directory. This can be easily done with a bash script.

It's been a month, and I'm interested in this! How are the tests coming?

Is there any progress for this issue or any code where you tried to integrate leanify into our optimization that we can look at ? I think a good way to implement and test other optimizer will be following the hints from here: #467 which are already implemented. ie. you need to create another compressor that extends the ICompress interface. Let us know what you think, if there is a way we can integrate the suggested optimizer ( leanify ) or we should close the issue ? Also here is an example of how to add an optimizer: #654

The ImageOptim app has a wide range of tools to investigate possibly using: https://imageoptim.com/mac
Specifically, it uses all of:

• oxipng
• pngcrush
• mozjpeg
• zopfli
• advpng
• jpegoptim
• gifsicle
• svgo
• svgcleaner
• pngout
