PowerArchiver 2017: jpeg support added to advanced codec pack (.pa)!
what do @Alpha-Testers think about inclusion of jpeg codec?
It seems to work nicely for me so far.
That link takes you to the main site.
Straight to the blog post.
Seems to be working fine, though I must confess that I rarely add jpegs to archives.
Lepton is a great choice. I would recommend to also use Lepton on progressive JPEG. That can be done using Lepton with -allowprogressive switch. I would also recommend to use your own JPEG codec where Lepton fails and maybe only in Optimize strong/extreme mode. Your own JPEG codec offers world-leading compression ratios. It may be worth introducing it.
@Stephan Isn’t their own codec one that reduces the quality? I’m not sure, but if so there would need to be clear warnings and an option to disable it.
right now there is no such option… our codec will be used only when always better than lepton, which it isnt… so lepton is always used.
Keep in mind that lepton (or any other codec available) does not support all jpegs. I believe dropbox focused on files that exist in real life vs trying to support every part of specification (like arithmetic jpegs) that actually dont get used in real life.
This is why for test, I went and collected different jpegs from different popular sites to compare vs WinZip jpeg and it did substantially better.
I have active Select plan. Where I can download PA 2017?
