SuperPNG 2.5

I just posted a new version of SuperPNG for your downloading pleasure. The big new feature is the Quantize checkbox, which will convert your 32-bit RGBA image into an 8-bit indexed color image with transparency. And I'm not talking about GIF-style 1-bit transparency here, but full 8-bit transparency values in the PNG color palette.

That 75% reduction in bits can really crush PNGs even more than was previously possible. Lower the quality slider to use fewer colors, which means even fewer bits and an even smaller file. This feature is powered by Kornel Lesiński's pngquant library, and Kornel has agreed to join me as SuperPNG's co-author.

Another new feature in this version is the Clean Transparent checkbox. It turns out that your transparent pixels may have unseen colors in them that are making PNGs harder to compress, but this feature will wipe them out for you. See the manual for more details.

SuperPNG has always been free, but now it's open source as well. Check out the GitHub repository and see exactly what we're doing.

Enjoy!

ProEXR 1.9

Today Adobe released a major update to After Effects and the rest of the Creative Cloud suite. This new AE ships with version 1.9 of the ProEXR plug-ins, which have been available here in beta form. Well, if the plug-ins are good enough for Adobe to ship them, I guess they're good enough for me. Consider version 1.9 released.

The biggest change in 1.9 is that the After Effects plug-in now handles displayWindow natively. Most users will not be affected by this, but the beta notice has more information for those interested.

The other subtle change is that all the ProEXR plug-ins are now built using OpenEXR 2.1, which supports multi-part files and deep image buffers. ProEXR can now read files that use these features, although the files you write will still be single-part flat images that are compatible with EXR readers that haven't yet upgraded.

Even if you're using an older version of After Effects, you can still download the latest ProEXR plug-ins and install them with your copy. Likewise, the Photoshop and Premiere plug-ins will work just fine in older versions of those programs.

As usual, this update is free and recommended for all ProEXR users. Enjoy!
