They have a huge size and your game now loads too slow???
Hello again. And again I decide do some work on optimizations! Our master Yuoki release a new versions for this period of time and I repack them again to be up to date.
Thanks mr. keyboardhack to open my eyes to beautiful pngquant utility. I start to search any similiar programs that can improve our results in compress of our factorio png-graphics. Then I find awesome compresser called pingo! On the site of pingo autor write a complex review of many png-optimizers! After hundreds of tests i decide to pick both pngquant and pingo to postprocess our graphics. Result is simply amazing, as always! Size reduced again, and again it's visually seems as original! Each image was processed by pngquant and then compressed ultimately with pingo. Images with gradients were optimized especially carefully and file by file to prevent quality loss.
Oh. Almost forget. I write a simple humble script - so anyone can now compress their png's like a boss (see readme in it for details).
I'm pleased to report that overall final size of four Yuoki's main mods is REDUCED from 271Mb to unbelievable 68,4Mb!!! ( -74,7% )
