Slims is a software that creates PNG files dynamically, allowing for efficient compression of images.
While there are other options available for handling static PNGs, Image::Pngslimmer can still be a useful tool. Keep in mind that filtering and recompressing images isn't a fast process. For example, the author processes PNGs at about 30KB per second on a 4300 BogoMIPS box with 1G of memory.
If you do decide to give Image::Pngslimmer a try, you'll have access to several helpful features. These include options to discard non-critical chunks and better compress the PNG image. You can even attempt to replace RGB IDAT with a palette (usually lossless) or a colour index palette (usually lossy).
To use Image::Pngslimmer, simply call the relevant function with your PNG image as the parameter. For example, you can check if an image is a PNG with the ispng() function or get a list of chunks with the analyze() function. There's also a reportcolours() function that will return details of the colours used in your PNG image.
Overall, Image::Pngslimmer is a useful tool for those seeking to optimize their PNG images for size. Just be prepared for the fact that it may take some time to process your images.
