[WIN] Paint.NET v5.1 正式便携版-电脑汇

Paint.NET是一款免费的图像编辑软件，由微软指导的大学设计项目，现在仍由一些最初的开发者维护。当时的意图是免费替换Microsoft Paint，但它继续成长为一个功能强大的照片编辑工具，类似于Photoshop、Paint Shop Pro、GIMP，当然还有Microsoft photo Editor。

使用Paint.NET的选项卡可以轻松处理多个图像，这些选项卡包括图像缩略图，还有特殊效果包括模糊，锐化，红眼去除，失真，噪音和压花。它还具有3D旋转/缩放效果，总之，功能上已经相当接近PS。

Paint.NET 5.1 更新日志：

Samsung SSD Magician v8.1.0 - 三星固态硬盘优化工具

New: Image->Color Profile replaces Image->Apply Embedded Color Profile, and provides the ability to change the image's color profile via Assign and Convert actions.
New: Fully modernized canvas presentation engine that utilizes DXGI Flip Model, Advanced Color, and Windows.UI.Composition.
Improved: Input latency has been significantly reduced by using DXGI Flip Model and Async Present.
New: Canvas section in Settings provides the ability to customize the canvas brightness, border color, and shadow
Improved the canvas rendering quality by using linear gamma. This improves overall performance and also improves the appearance of selection handles and other canvas UI elements.New: Effects->Blur->Sketch Blur is a new blur effect that gives the appearance of a painting drawn with a coarse brush.
New: Effects->Blur->Median Blur replaces Effects->Noise->Median, and now runs on the GPU with much higher quality.
New: Effects->Blur->Square Blur
Changed: Gaussian Blur and Bokeh Blur now have a "Gamma Boost" slider instead of a "Gamma" property. This is now used to configure the change in gamma rather than specifying the gamma that the image should be assumed to have. The intent is still to provide something of a brightness/highlights amplifier for creative purposes.
Changed: Effects -> Blur -> Motion Blur now uses a Gaussian kernel.
New: Effects->Render->Clouds now has a Colors tab for configuring the colors that are used
Changed: Image->Canvas Size will no longer use the secondary color to fill in new areas for the "background" layer. It will always fill with transparent black (#00000000).
Improved dithering quality when saving an image at 8-bit or lower color depth, and when using Effects->Color->Quantize
New: Updated to use Mica effects in the title bar on Windows 11
Fixed some more scrollbars to respect dark theme (thanks @toe_head2001!)
Fixed: The Move Selected Pixels tool will no longer finish (commit) when toggling layer visibility. This was a workaround for a bug during an early beta of 4.0 that does not seem to be necessary anymore.
Improved: Greatly reduced CPU memory usage by maintaining the tile cache only on the GPU instead of having a copy on the CPU-side as well.
Improved: Significantly reduced GPU memory usage by consolidating down to 2 swapchains that are shared among image tabs, instead of each image tab having its own private swapchain.
Improved: GPU effects now use a smaller tile size on GPUs with less RAM, which should enable faster updates and cancellation response on older GPUs. This also significantly lowers the probability of TDR events, particularly for expensive effects like Median Blur.
Fixed: The Save Configuration dialog sometimes looked like it was having a seizure when panning after zooming (w/ Ctrl + Mouse Wheel)
Fixed: The Line/Curve and Shapes tools would cancel instead of commit (Finish) when pressing ESC too soon after using the arrow keys to move the shape
Improved the performance of the portable release by reducing how often the JSON settings file is flushed.
New: CMYK64 images can now be loaded. Note that CMYK images are always transformed to Adobe RGB.
New: Added the ExponentialScale double property for IndirectUI. The default value is 2.0. It goes along with the UseExponentialScale boolean property.
New: GPU effect plugins can now use compute shaders. Note that this is "raw" support by providing access to the necessary Direct2D interfaces (e.g. ID2D1ComputeInfo).
Deprecated: The classic/legacy effect system has been marked as [Obsolete]. Compiling a classic/legacy effect will produce a compile-time warning along with a message about migrating to the new GpuEffect or BitmapEffect systems. This will be changed to a compile-time error in a future update (either v5.2 or v6.0, whichever is next).
Removed: Settings -> UI -> Show image previews in the Windows taskbar.
Removed: Settings -> UI -> Enable scrolling past the edge of the canvas (overscroll). This is now always enabled.
Updated to use .NET 9.0 (previously this was .NET 7.0)
Updated the minimum OS requirement to Windows 10 v21H2 (previously this was Windows 10 v1809)
Updated the bundled AVIF FileType to version 3.10.0.0. Thanks @null54!
Updated the bundled DDS FileType Plus to version 1.12.11.0. Thanks @null54!
Updated the bundled WebP FileType to version 1.4.0.0. Thanks @null54!
