paint.net 4.3 alpha (build 7878)

5 Comments

This update took quite a bit longer than I anticipated (3 weeks instead of 1), but the good news it that there’s a lot to like here!

I’ve bumped the version to 4.3 (was 4.2.17), added native ARM64 support, and optimized a whole bunch of important rendering code paths. In addition, the quality of selection antialiasing has been improved by using a 4×4 super sampling filter, whereas before it was 3×3. There should be no performance loss because this is now optimized to use vectorized SSSE3 instructions (“SIMD”) on x86/x64 systems.

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 4.2.17 alpha build 7858:

  • New: ARM64 is now natively supported, which includes devices such as the Surface Pro X
  • 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 4×4 super sampling filter instead of 3×3. 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: 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: If a download fails in the Prerequisites Installer, it will retry and resume up to 10 times, thus greatly improving its reliability for downloading things like .NET 5 and the Visual C++ Runtime
  • 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.

Enjoy!

paint.net 4.2.17 alpha build 7858–now using .NET 5!

8 Comments

Paint.NET has finally been migrated to .NET 5! If you’re not familiar, .NET 5 (also known as .NET “Core” 5.0) is the new version of .NET that replaces .NET “Framework” (of which no more new versions will be made). More info here: https://devblogs.microsoft.com/dotnet/introducing-net-5/

It was a very large effort to move Paint.NET over to .NET 5 over the last 2 months! Most of that effort went towards rebuilding from scratch how Paint.NET is built and packaged (installer, MSI, APPX, portable ZIPs), because the old solutions were showing their age and were no longer serviceable. The app itself required only minor changes to work on .NET 5.

You should not really see any difference in the app’s features or the way it behaves, although performance has improved. Sometimes substantially! Sadly there are some plugins that will no longer work, although I may be able to find fixes for some of them.

I will be releasing this via the built-in updater sometime later this week. For now, I want to start with a smaller audience, so you must download and install it manually. Just close the app, run the installer EXE inside the ZIP, and it will do everything for you (as usual):

The download link for the installer is available at the forum page about this release.

You may also download a portable version of the app, which is useful if you just want to try things out or are not yet ready to fully commit to the new version. .NET 5 is built-in, so there is no need to install it (the app is “self-contained”). The portable version of the app will save settings in a local JSON file instead of using the registry.

The downloads links for the portable ZIPs are available at the forum page about this release.

If you have an ARM64 device such as the Surface Pro X, you may also install the app. For the portable ZIPs, use the architecture appropriate for your operating system: x86 for Win10, or x64 for Win11. This is untested, so please report back with how well it works.

Changes:

  • The app has been migrated to .NET 5, and performance has been greatly improved as a result.
  • 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
  • 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/
  • 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)
  • Updated the built-in AvifFileType plugin to v1.1.13.0 (courtesy of @null54). See the project’s GitHub Releases page for more information.

Known Issues:

  • If you have a lot of plugins installed, such that the Effects menu is too large for the screen and must be scrolled, the scroll indicator buttons (the up/down arrows) are a lot larger than they should be. This seems to be a bug in .NET 5.
  • Several of Ed Harvey’s popular plugins are blocked because they are not compatible with .NET 5. I may find a solution for this, but it may also require a new version of the plugin to be released.
    • Color Flip/Rotate
    • Threshold
    • Glass Blocks
    • Color Filter
    • Filtered Black and White
    • Single Hue
    • Color Tint
    • Vitrious
    • White Balance

paint.net 4.2.16 is now available

This updates fixes and optimizes palette generation when saving at 8-bit depth or less, and also fixes any remaining issues with using "Auto-detect" for bit-depth. A new effect, Quantize (in the Effects -> Color menu), has been added, some bugs have been fixed, and bundled file type plugins have been updated.

Here’s a simple example of using Quantize to reduce the # of colors in an image. You can also apply dithering, just like you can when saving an image at 8-bit or lower bit-depth. You can also choose between the Octree (default) and Median Cut palette generator algorithms. Octree is generally the right choice, but Median Cut can occasionally be quite useful.

If you’re using the Windows Store release, you should get the update automatically within the next 24 hours. You can also force an update check by following these instructions.

For the Classic release, you should be offered the update automatically within the next week or so. You can get the update sooner by going to ⚙ Settings → Updates → Check Now. You can also download and install it directly from the website.

List of changes since 4.2.15:

  • New: Effect -> Color -> Quantize, which applies palette reduction to 256 colors or less, along with dithering. This is the same algorithm used when saving images at 8-bit color depth or lower.
  • Fixed and improved palette generation when saving at 8-bit color depth or less
  • Greatly optimized performance of palette generation and image quantization
  • Added option to choose between Octree (default) and Median Cut algorithms for palette quantization when saving at 8-bit color depth or less
  • Fixed a crash in Move tools when the selection was 0-width and/or 0-height
  • Added tooltips w/ shortcut keys to the Tools dropdown in the toolbar
  • Fixed IndirectUI ColorWheel rendering (thanks @toe_head2001!)
  • Fixed a crash in the Text tool when using Ctrl+(Left,Right,Backspace,Delete) (thanks @Bruce Bowyer-Smyth!)
  • Changed: New layers are now filled with #00000000 instead of #00FFFFFF
  • Fixed a crash when working with selections (OutOfMemoryException)
  • New: Effects can now access the Document’s DPI via EffectEnvironmentParameters.DocumentResolution
  • Fixed drawing of the color palette in the Colors window when using some non-standard DPI scaling settings (e.g. 1.15x)
  • Fixed a crash when using @Ed Harvey‘s Threshold plugin
  • Fixed the return value from PdnRegion.GetBoundsInt() so it’s not anchored at (0,0) unless it should be
  • Fixed premultiplied-to-straight color conversion on some code paths (thanks @null54!)
  • Updated bundled AvifFileType plugin to v1.1.11.0, which includes performance optimizations and bug fixes. See its GitHub releases page (https://github.com/0xC0000054/pdn-avif/releases) for more info. (thanks @null54!)
  • Updated bundled DDSFileTypePlus plugin to v1.10.9.0, which uses an updated version of DirectXTex (2021-04-06). (thanks @null54!)

Enjoy!

paint.net 4.2.16 beta build 7765

Now that I’m getting back into the swing of things after having moved across the country (Bay Area -> back to Seattle area, finally!), it’s time for a new update :)

This release is mostly focused on fixing, improving, and optimizing the quantization code. This is used when you save an image at 8-bit or lower color depth. There have been a number of bugs that have plagued this over the years, including 1) the generated palette is way too small (e.g. for a black->red gradient, it’d be 64 colors instead of 256), 2) the generated palette is slightly too small (e.g. 252 colors instead of 256), 3) the precision of the colors would be biased in favor of those that are at the top of the image, 4) the palette has colors removed from it that shouldn’t have been (this plagues Auto-detect), and more recently 5) the generated palette, especially for a low color depth, is complete trash.

#1 was a result of a bug in the Octree code that goes all the way back to the MSDN article it was pulled from, https://docs.microsoft.com/en-us/previous-versions/dotnet/articles/aa479306(v=msdn.10)?redirectedfrom=MSDN . As it turns out, shifting right (via >>) by a negative amount results in 0 instead of a shift left. Maybe C works that way, but C# does not.

#2 was a result of the way that reduction/merging works in the Octree data structure. It can only merge an entire node’s children, meaning it can reduce 8 colors into 1, but never 8 colors into 2 through 7. This means it would undershoot the desired palette size as much as 6/7th of the time. I fixed that with a trick I learned at https://www.codeproject.com/Articles/109133/Octree-Color-Palette (search for the word "vomit" ).

#3 happens because the Octree code would reduce nodes in an order defined by how they were added to the octree. Since the image is processed top-to-bottom, this would thus favor colors that first appear at the top. I’ve fixed this by more evenly spreading out which leaf nodes are merged — those with lower frequencies are merged first, and if two colors have the same frequency then the ordering is deterministically pseudo-randomized by using the color’s hash code.

#4 was kind of a mix between 1, 2, and 5. There have been several reports of images that should be correctly auto-saving at 4-bit color depth (because of using <=16 colors), but colors are still trimmed. Auto-detect is strictly required to be lossless, and it has been failing at that. My new code for the Octree algorithm should fix this, but I’ve also added code to skip palette generation entirely if the desired color count is greater than the # of unique colors in the image (an obvious shortcut/fix, but the code was a bit snaky in terms of permitting this). This also means Median Cut will behave properly, because WIC’s code does not necessarily do this correctly either.

#5 was a result of switching from my Octree code to WIC’s Median Cut. As it turns out, Median Cut isn’t a good choice for a lot of images even when it’s correctly implemented. In addition to having some really bad bugs with large images that I’ve had to work around, WIC’s implementation also falls completely flat on its face when the palette size is small. Imagine a black->white gradient that gets bits of cyan and magenta sprinkled throughout. Ugh. I have retained the ability to use Median Cut, although Octree is the default.

I’ve also optimized these things to be a lot faster and use a lot less memory.

You can see all of this in effect if you save an image as a PNG, GIF, TIFF, or BMP at 8-bit, 4-bit, 2-bit, or 1-bit color depth. You can also use the new Effect -> Color -> Quantize effect to play around with it. It lets you specify an exact palette size instead of the bit-depth.

This is a small update that improves some quality-of-life issues, and fixes some important crashes due to mishandling of some non-fatal DirectX errors.

If you’re using the Windows Store release, you should get the update automatically within the next 24 hours. You can also force an update check by following these instructions.

For the Classic release, you should be offered the update automatically within the next week or so. You can get the update sooner by going to ⚙ Settings → Updates → Check Now. You can also download and install it directly from the website.

List of changes since 4.2.14:

  • New: "Tolerance Alpha Mode" toggle button added to the toolbar for the Magic Wand, Paint Bucket, and Recolor tools. This permits switching the algorithm for color comparison between premultiplied (default) and straight. "Straight" will distinguish between transparent pixels with different color values, whereas premultiplied will see them as equivalent.
  • New: Holding Ctrl while using the Color Picker tool will sample from the merged image (vs. just the current layer)
  • New: The file name in the title bar will now have a prepended asterisk when it has unsaved changes
  • Changed: The image close ‘X’ button can now be clicked for images that are not currently active
  • Changed: In the Text tool, Ctrl+(Backspace, Delete, Arrow Keys) has been improved to work more like Microsoft Word. Thanks to @Bruce Bowyer-Smyth for the patch!
  • Fixed: The Rectangle Select tool, when used to draw a constrained, fixed ratio, or fixed size selection, will now correctly clamp the rectangle to be within the canvas
  • Fixed: Layers -> Move Layer Up/Down/Top/Bottom was not working for images with fewer than 3 layers
  • Fixed: Edit -> Erase Selection will now fill with transparent black (#00000000) instead of transparent white (#00FFFFFF)
  • Fixed: Custom Shapes will now be displayed in a consistently sorted order
  • Fixed: ".pdnSave" ghost files should no longer linger when saving to the desktop. This was due to a bug in Windows and File Explorer.
  • Fixed crashes due to DXGI/Direct3D "lost device" or "device removed" errors that can happen for various reasons (duck/undock, driver update, low memory, etc.)
  • New: Plugins can now use the IArrayPoolService, a wrapper around .NET’s ArrayPool, to optimize their array allocations
  • Updated bundled AVIF FileType Plus to v1.1.6. See the pdn-avif releases page on GitHub (https://github.com/0xC0000054/pdn-avif/releases) for more information.

Enjoy!

(Forum discussion here)

This update includes full support for AV1 (*.avif) images, courtesy of @null54‘s AvifFileType plugin, which is now bundled.

In addition, I’ve spent a lot of time optimizing various parts of the canvas rendering engine. Memory usage and CPU usage are both lower across the board, which should help when working with large images, as well as images (large or small) with many layers. I’ve also made several bug fixes and improvements to the Move Selected Pixels, Magic Wand, Paint Bucket, and Ellipse Select tools.

If you’re using the Windows Store release, you should get the update automatically within the next 24 hours. You can also force an update check by following these instructions.

For the Classic release, you should be offered the update automatically within the next week or so. You can get the update sooner by going to ⚙ Settings → Updates → Check Now. You can also download and install it directly from the website.

Changes since 4.2.13:

  • New: AV1 (*.avif) images can now be saved (not just opened), due to bundling of @null54‘s AvifFileType plugin (v1.1.4.0). Installation of Microsoft’s codec from the Microsoft Store is no longer necessary, which means this also works on Windows 7 and 8.1.
  • Improved performance and memory usage in the canvas rendering engine, especially when working with large images or images with many layers. This is most noticeable when scrolling and zooming.
  • Improved CPU usage when a selection is active and when GPU accelerated rendering is disabled
  • Improved CPU/GPU usage when a selection is active but the app is not (the animation is disabled)
  • Reduced memory usage when working with images that have regions of solid color
  • Fixed the Magic Wand and Paint Bucket tools so that they do calculations in the premultiplied alpha color space. This ensures that transparent colors (alpha=0) with different RGB values are treated as equal, and do not create borders.
  • Fixed the Move Selected Pixels tool so that it fills the uncovered region with 0 (transparent), instead of a transparent version of the secondary color.
  • Fixed: Backspace now works correctly in the Colors form: it does not execute Edit -> Fill Selection
  • Fixed an issue where saving an image at 4-bit color depth (usually pixel art) was using an incorrect palette (reduced color count/quality). This was due to a bug in Windows Imaging Component (WIC).
  • Greatly improved performance when saving images at 8-bit color depth
  • Fixed an issue where very large images (e.g. 50000 x 50000 px) couldn’t be saved at indexed bit-depths (8-bit or less) due to a bug in Windows Imaging Component (WIC). More information on the forum: https://forums.getpaint.net/topic/116950-error-when-saving-a-big-file/
  • Fixed an issue where BMP images couldn’t be loaded if they had the .PNG extension (there’s an Android screenshot utility out there which does this …)
  • Improved: Ellipse Selection Tool’s now tessellates at a higher resolution, resulting in smoother circles at small sizes
  • Fixed a rare crash in the Gradient tool (“The tool must be in the Drawing state …”)
  • New: Added a list of the DLLs that are loaded into the process on the Settings → Diagnostics page. This is to help troubleshooting scenarios.
  • Fixed an issue with copying large images to the clipboard: if an image would take up more than 4GB, it could not be copied because the DIB and DIBV5 formats cannot be larger than that. Now, the DIB and DIBV5 formats are not placed on the clipboard if this happens.
  • Fixed an issue with Effect plugin tooltips which was preventing the menu item from being easily clicked (thanks @toe_head2001 for the fix!)
  • Fixed an issue that was preventing Effect configuration dialogs from working correctly in the Visual Studio designer (thanks @toe_head2001 for the fix!)
  • Added diagnostics information to most error dialogs. This is to help with troubleshooting.
  • Fixed: Scanning will now apply the DPI (resolution) from the scanner to the image, if possible
  • Updated bundled DdsFileTypePlus plugin to v1.10.7.0. See the pdn-ddsfiletype-plus change log on GitHub for more information. Thanks @null54!

Enjoy!
