paint.net 4.3 alpha build 7879


Recommended Posts

This build isn't too exciting, fresh off the heels of yesterday's 4.3 alpha build 7878, but it's important: it fixes a crash when running an effect with a selection active! (unless the selection was just simple rectangles)

 

To get this update, make sure you have "Also check for pre-release (beta) versions" enabled in Settings, and then click on the Check Now button. (Unfortunately alpha/beta releases are not currently available for the Microsoft Store version of the app).

Changes since 4.3 alpha build 7878:

  • Fixed a crash when running an effect while a non-pixelated selection (not just simple rectangles) was active

 

The complete list of changes so far for 4.3, as compared to 4.2.16:

  • New: The app has been migrated to .NET 5, and performance has been greatly improved as a result.
  • New: ARM64 is now natively supported
  • Installation is much faster now due to no longer needing the "Optimizing performance for your system" stage (NGEN has been replaced with ReadyToRun via crossgen).
  • Portable ZIPs are now officially available, utilizing self-contained deployment, and do not require the installation of .NET 5. You must manually update to newer versions of the app, however.
  • Improved performance of most effects and other compute-intensive tasks by about 20% on average, due to .NET 5's improved code generation
  • Improved: Many areas of the app have been optimized to use SIMD (SSE2/3/4.1, AVX2) on x86/x64
    • Drawing on an image with a large number of layers is faster
    • Drawing with the Gradient Tool's alpha mode is faster
    • Drawing with the Recolor tool is faster
    • Drawing with the Erase or Clone Stamp tool is faster when using a color whose alpha value is less than 255
    • Drawing with the Overwrite blend mode is faster
    • Drawing with the Shapes tool is faster, due to improved compositing performance
    • Drawing with a brush tool without antialiasing is faster
    • Tile compression has lower overhead due to being optimized for SSE2 and AVX2
    • Working with complex selections is faster
    • Many other optimizations all throughout the application and rendering engine
  • Improved: Selection antialiasing quality is now better by way of using a 4x4 super sampling filter instead of 3x3. The code has also been optimized to use SSSE3 on x86/x64.
  • Improved: Performance should be significantly better on systems without HyperThreading (by reserving 1 core for the UI), and also a bit better on systems with it (by utilizing more of the logical cores)
  • Improved: Effect and File Type plugins can now be organized into folders -- the plugin loader will recursively search for DLLs up to 1 folder deep
  • Fixed a bug in Polar Inversion that was causing hangs
  • Improved performance of Polar Inversion by 3x, due to the aforementioned bug fix (and a little bit is due to .NET 5)
  • Fixed: There were some issues with zooming in/out using the keyboard, where the anchoring (centering) point was not calculated correctly, causing the canvas to drift in the wrong direction.
  • Fixed a bug when saving with "Auto Detect" bit-depth that was causing fidelity loss on some images that already had 256 colors or less. This was reported here: https://forums.getpaint.net/topic/118401-images-already-with-256-or-fewer-colors-being-dithered-when-saved-with-palette/
  • Changed: A processor that supports SSSE3 (yes 3 S's) is now required for x86/x64 systems (previously only SSE2 was required). All CPUs released since about 2006 (e.g. Core 2 Duo) support this.
  • Known Issue: Due to crashing, GPU accelerated effects (Gaussian Blur, Motion Blur, Radial Blur) on ARM64 will actually use the CPU for rendering.
  • Updated the built-in AvifFileType plugin to v1.1.13.0 (courtesy of @null54). See the project's GitHub Releases page for more information.

Good news, I have a fix for @Ed Harvey's effects. The theming still doesn't work, but that was the case in 4.2.16 as well. I'll put out an update shortly.

 

(I got it to work by rewriting the IL code using Mono.Cecil to fix some broken use of reflection 😂 It was just crazy enough that it worked... I also had to strip out a few unused properties that were of type ContextMenu)

 

Ed should still put out updated versions of his plugins, but this at least means we won't have untold number of happy plugin users suddenly in an unhappy state, all e-mailing me and making forum posts asking how to get their effects to work again. Win-win-win situation.
