Paint.NET 3.5.2 Beta 1

這套影像編修軟體擁有親切好用的介面，並支援圖層、無限次數的復原以及各種特效處理。為了更容易使用，Paint.NET利用縮圖標籤頁介面，取代以往的文字標籤頁。

• 它有針對Windows 7或Vista特別做介面上的加強。
• 不論是使用Atom CPU筆記型電腦或是雙核心的桌上型電腦，都可以在這套軟體上體驗到快速啟動及回應的快感。
• 結合線上談壇，擁有多個社群討論區，可互相切磋精進。
• 多種特效濾鏡，包括模糊、銳利化、變形、雜訊、去除紅眼等等。
• 無限制的回復次數，暫存容量僅限於可用的磁碟空間大小。

* All font face variants (e.g., Arial vs. Arial Narrow) are now available with the Text tool in Win7/Vista with DirectWrite.
* Bitmap font types (e.g. Courier, Terminal, Fixedsys) are now available with the Text tool in Win7/Vista.
* Fixed some bad text kerning with the Text tool at small font sizes when antialiasing was turned off.
* For the Image->Resize function, the quality, correctness, and performance of Bilinear and Bicubic sampling modes have been improved. Super Sampling also has some performance improvement.
* Improved the rendering quality for the Hue/Saturation adjustment. Also made a new icon for it.
* Fixed many subtle rendering issues with the Move Selected Pixels tool. These were apparent when flipping or rotating a selected area.
* Fixed: The Line/Curve tool was applying pixel snapping to the curve nodes, which caused lines to "bend" when using the Shift key to constrain the angle.
* Fixed some extraneous CPU usage related to unnecessary or redundant thumbnail updates.
* Fixed a few dialogs that looked wrong with Aero glass with Remote Desktop or Virtual PC.
* Fixed a nasty memory leak with Flatten followed by Undo.
* Fixed some issues related to effects that took awhile to cancel. As it turns out, drag-and-drop was enabled at this time, which easily lead to crashes or hangs.
* Some Win7 systems could not detect that .NET 3.5 SP1 was installed, even though it was. A fallback detection function has been added.
* For plugin authors, the Effect class now has a pollable IsCancelRequested property. This can be used to improve responsiveness for expensive OnSetRenderInfo() implementations which are otherwise non-interruptible.
* For plugin authors, the Surface.FitSurface() method is now optimized to use multiple threads, which improves performance.
