New Test Builds: changes to Flow and Saving/Loading

Published    1/25/2019

Krita needs you! We’ve new test builds of what will become Krita 4.2. There are two changes that we really would like everyone to test!

DO NOT USE THIS FOR REAL WORK. ONLY FOR TESTING.

YOU MIGHT LOSE YOUR WORK!

First, following two discussions on the forum, William Brown created his very first patch for Krita. This changes the way flow and opacitiy interact:

Comparison of new and old Flow handling

Now these changes really touch the core of what Krita does, that is painting, so we’d like all of you to go out, download a test build and play with it.

The second change is even scarier… We swapped out the engine that encodes and decodes Krita files.

Krita’s .kra format is actually a simple zip file. And simple zip files have a limit: they cannot be bigger than 4GiB.  And it turns out that people working with animations sometimes do make files bigger than that…

So we are now using a new library, quazip, that supports the Zip64 standard. But we use that library now wherever we load and save .kra files, but also OpenRaster files, resource bundles — everything that’s a zip file. By default, Zip64 is disabled: if you’re working on big animations, you need to manually enable Zip64 functionality:

Note that Zip64 files cannot be loaded in older versions of Krita! But we also need you test whether everything is okay when Zip64 is disabled.
