Paint.NET 4.2

,

Paint.NET或许很多人和我一样,在有的时候需要一款能简单处理图片的软件,功能要求也不高,就是加个文字注释,更改一下图片大小之类的。为了这些简单功能我们去安装强大的Photoshop?No No No,杀鸡焉用牛刀?下面这款Paint.NET就可以满足这样的需求。

Paint.Net的开发初衷仅仅是为了增强Windows自带的Paint,不过现在它的功能已经远远超过这个目标了,而且在插件的帮助下,它的功能也越来越强大,虽然不及Photoshop,但是并不是每个人都需要那么专业化的软件,我们仅仅需要一款轻巧的简单图像处理软件,这就够了。

Paint.NET最近的更新也很频繁,或许是上个版本发布的太匆忙,这次更新修复了不少Bug。或许这些都不是什么重点,重要的应该是其提供了对.Net Framework 4.0的支持。好吧我知道很多朋友对于Paint.NET这款软件对.Net Framework的密切依赖颇有微词,不过在Windows 7越来越普及的趋势下,我认为这应该不会成为一个问题了吧。

paint.net 4.2 – Download, released on July 13th, 2019

This is a big update that focus on adding HEIC file format support, fixing performance with very large images, and upgrading and modernizing the functionality of many existing file types (JPEG, PNG, BMP, GIF, and TIFF). Many other quality of life issues have also been addressed or fixed.

New: Support for loading and saving HEIC images (Windows 10 v1809+ and codec installation is required). Please note that the “Quality” slider when saving is limited to a value of 90 (out of 100) while Microsoft investigates and fixes a crash in their codec.
New: Keyboard shortcuts for changing the current layer. You can see these in the Layers menu with the “Go to …” commands. Alt+PgUp/PgDown will go to the layer above/below, and Ctrl+Alt+PgUp/PgDown will go to the top/bottom layer.
Fixed: Optimized rendering engine to remove huge lag spikes (30+ seconds) when zooming or panning very large images (e.g. 32K x 32K pixels).
Improved: BMP now supports saving in 32-bit (with alpha!) and 8-bit indexed.
Improved: Added DIB and RLE file extensions to the BMP file type.
Improved: PNG, JPEG, and TIFF now support loading and saving of much larger images.
New: PNGs can now be saved as “interlaced”.
Improved: JPEG now has configuration for the chroma subsampling mode (4:4:4, 4:2:2, and 4:2:0). The default is now 4:2:2 instead of the unconfigurable 4:2:0 of older versions. This may result in larger file sizes, but higher quality, as compared to previous versions.
Improved: TIFF now supports saving at 24-bit and 8-bit color depths.
Improved performance of saving for file types where “Auto” bit-depth is supported but is not the current choice.
Improved temporary memory usage when saving images at 8-bit color depth.
Improved: TGA images now load about 4x faster (thanks @null54!)
Fixed: 8-bit TGA images should now load correctly (thanks @null54 for the fix!)
Fixed: Some 32-bit TGA images were showing up as completely transparent due to their use of an obscure alpha channel type (thanks @null54 for the fix!)
Improved: Added error reporting to the Save Configuration dialog. Instead of just saying “Preview: (error)”, you’ll also get the standard error dialog that includes the exception which can used for troubleshooting.
Fixed a number of performance issues in the Save Configuration dialog. Especially with large images, it should now be much faster to change options and to click OK/Cancel.
Fixed flickering in the Save Configuration dialog when changing options.
Fixed: Windows Explorer thumbnails for some image types (PDN, DDS, TGA) were not rendering their alpha (transparency) correctly, resulting in color skew. You may not see the effect of this fix for a particular image until that image is resaved or you clear Explorer’s thumbnail cache.
Fixed: Mouse cursors now scale appropriately for non-integer UI scales (e.g. 125% or 175%)
Fixed: AltGr should now work correctly with the Text tool. It will not trigger shortcuts like File->Save All, or Edit->Paste into New Image. (thanks @Bruce Bowyer-Smyth for the fix!)
Changed: Image->Resize supports Super Sampling again, and favors this over Fant when using Best Quality. Fant is still available, but is no longer chosen automatically.
Changed: Holding Ctrl when starting to move a selection with the Move Selected Pixels tool will no longer leave behind a copy of the selected area
Fixed: Bicubic resampling in the Move Selected Pixels tool was not correctly handling the alpha channel in some cases. This fix has required a reduction in performance.
Improved: When using Edit->Copy, a 32-bit BGRA bitmap in the DIBV5 format is now placed onto the clipboard so that other apps can read the alpha channel.
Improved: When using Edit->Paste, DIBV5’s are now supported if they have an alpha channel. If they don’t, then the regular DIB loader is used which has some heuristics for detecting an incorrectly defined alpha channel and correcting for it.
Improved: When using Edit->Paste, PNG is now the highest priority format. This maximizes the ability to maintain alpha/transparency, but it does mean that images coming from Microsoft Office apps will appear larger than they used to. This is either a bug or a feature of Microsoft Office. For some reason it places PNGs on the clipboard that are 25%+ larger than the DIB/DIBV5 bitmap that it also places on the clipboard (but which don’t have alpha/transparency).
Fixed: DIBV5 bitmaps should now work with Edit->Paste, which improves alpha channel handling. (thanks @null54 for the fix!)
Fixed: Top-down DIBs should now work correctly with Edit->Paste. (thanks @null54 for the fix!)
Improved CPU usage for thumbnail updates (layers and image tabs) in many cases.
Improved: Slightly increased the size of the Settings dialog to reduce the need for scrolling in a few important situations
Fixed: Simple message boxes can now be closed with the ESC key
Fixed: Magic Wand now works on very large images (e.g. 65535 x 65535 pixels) without an error.
New: Plugins that use IndirectUI can now use a UriProperty with a LinkLabel control (thanks @null54!)
New: Effect plugins can now more easily make use of the clipboard via the IClipboardService. It will handle all of the tricky clipboard issues such as threading, native data marshaling, and avoiding security vulnerabilities that exist in the standard WinForms and WPF clipboard APIs.
New: FileType plugins can now specify separate lists of extensions for loading and saving.
Blocked the WebP FileType v1.1.0.0 plugin due to instability. An update is already available.
Blocked the ImAgif FileType v0.12.0.1084 plugin due to incompatibility. An update will hopefully soon be available.

Minimum System

Windows 10 (version 1607 “Anniversary Update” or newer)
or Windows 8.1
or Windows 7 SP1 with Platform Update
1GHz processor (dual-core recommended)
