经过两年的发展，自由开源的照片编辑器 PhotoDemon 的作者已推出了 PhotoDemon 9.0。新版本增强了用户界面，内置了对 Adobe Photoshop 插件的支持，支持了新的图像格式，减少了资源使用等等。根据用户在 “<ruby> 工具 <rt>  Tools </rt></ruby> > <ruby> 选项 <rt>  Options </rt></ruby> > <ruby> 更新 <rt>  Updates </rt></ruby>” 下的设置，已经安装了 PhotoDemon 9.0 可以自动收到更新推送。你也可以选择通过 “<ruby> 帮助 <rt>  Help </rt></ruby> > <ruby> 检查更新 <rt>  Check for Updates </rt></ruby>” 手动更新。


PhotoDemon 这个便携程序提供压缩包下载。解压到系统，就能启动这个照片编辑器。可能最新版本会让Windows 可能会发出 SmartScreen 警告，VirusTotal 上的两个不太知名的杀毒软件也会报毒（以上都是误报）。新的 PhotoDemon 消耗的资源比以前的版本少，这是它的优点之一。例如，它在冷启动后使用的内存也比以前的版本少 12%。


用过老版本的用户切换到新版本可能会立即注意到新的界面。比如大多数选项现在都以弹出的方式显示，最常用的工具显示在工具栏上。根据作者的说法，新的用户界面使用了“旧版本不到一半的垂直空间”，而且不会牺牲功能。


用户界面仍然可以适配各种显示分辨率，包括 1024×768 这样的传统分辨率。且新版本中打开的照片会有更多空间。在早期的版本中，照片编辑器的选择工具表现出色。最新版本中包含对多选区的支持。添加选区、减去选区和相交选区可用于组合选择，即使在多个选区处于活动状态时，你仍然能编辑刚创建的选区。


内容填充工具，通常称为智能对象移除或涂抹，是另一个新功能。要使用它，用户可以选择 “<ruby> 编辑 <rt>  Edit </rt></ruby> > <ruby> 内容填充 <rt>  Content-aware fill </rt></ruby>” 或 “<ruby> 选择 <rt>  Select </rt></ruby> > <ruby> 修复选区 <rt>  Heal selected region </rt></ruby>”。虽然该工具是自主操作的，也能个性化一些设置和选项。该功能既不需要人工智能也不需要互联网连接。事实上，正因为如此，如果多次运行该工具可能会带来更好的图片。


PhotoDemon 9.0 支持新的图像格式。新版本提供 PSP 图片、AVIF 和动画 WebP 图像的导入和导出功能。尽管有 AVIF 支持，但由于其大小，并未内置必要的编码器和解码器应用程序。用户首次加载或保存 AVIF 文件时会下载必要的数据。现在可以导入 XCF（GIMP）、SVG 和 SVGZ 格式的图像。


最后但同样重要的是，PhotoDemon 9.0 支持无损 “quite OK”（QOI）照片、Symbian 图像（MBM 和 AIF）、漫画书档案（CBZ）和无损 JPEG（JPEG-LS）图像。作者称最新版本中的自动优化 GIF 的功能是同类产品中最佳的。新的神经网络颜色量化器也有助于依赖调色板的图像格式。


PhotoDemon 9.0 的新增增强功能包括：


* 图像调整器提供了 12 种复杂的重采样技术的实时交互式预览。
* 支持内置的 Adobe Photoshop 插件（8bf）。
* 完全支持 3D LUT（三维查找表）。
* 新效果包括渐变流、凹凸贴图、Droste 和 Truchet 贴图。
* 改进了结晶和染色玻璃的工具。
* 一种新的去雾工具，用于恢复“被雾霾或雾霾破坏”的照片。
* 新的用户界面和改进的工具性能曲线。
* 为了“更好地匹配 Photoshop 的实现”，照片滤镜工具已经过重新设计。

OK
After two years of development, the creators of the free and open source photo editor PhotoDemon have launched PhotoDemon 9.0. The new version has enhanced user interface, built-in support for Adobe Photoshop plugins, support for new image formats, reduced resource utilisation, and more. Depending on their selections under Tools > Options > Updates, users who already have PhotoDemon installed on their devices can automatically receive the update. To perform a manual update check and install the update on the device, select Help > Check for Updates.

A portable programme called PhotoDemon is offered as a ZIP archive. After extracting the ZIP archive to the system, you can launch the photo editor. Due to the newness of the new version, Windows may issue a SmartScreen warning. Two hits from less well-known antivirus engines that are (presumably) false positives are returned by VirusTotal. The fact that the new PhotoDemon consumes fewer resources than the previous version is one of its primary benefits. For instance, it uses 12% less memory than the prior version after a cold start.

Users who switch to PhotoDemon version 9 from a previous version might immediately notice the new user interface. The majority of options now display as flyout panels, and the most used tools now appear right on the toolbar. The new user interface, according to the creator, uses “less than half of the vertical space of the old design” without sacrificing functionality.

The user interface is still made to work with a variety of display resolutions, including traditional ones like 1024×768. With the makeover, photographs that are opened in the editor have more space. In earlier iterations, the photo editors’ selection tools performed admirably. Support for multiple selections is included in the most recent release. Add, Subtract, and Intersect can be used to combine selections, and even when several selections are active, the final selection is still editable.

The content-aware fill tool, often known as smart object removal or inpainting, is another new function. To use it, users can choose Edit > Content-aware fill or Select > Heal chosen region. Although the tool operates automatically, there are settings and adjusting choices to personalise the process. Neither artificial intelligence nor an Internet connection are needed for the instrument. In fact, because of that, running the tool more more once might lead to better outcomes.

In PhotoDemon 9.0, new image formats are supported. The updated release provides import and export functionality for PSP pictures, AVIF and animated WebP images. Although there is AVIF support, the necessary encoder and decoder apps do not come with the programme due to their size. The necessary data is downloaded the first time an AVIF file is loaded or saved by a user. Images in the formats XCF (GIMP), SVG, and SVGZ can now be imported.

Last but not least, PhotoDemon 9.0 supports lossless “quite OK” (QOI) photos, Symbian images (MBM and AIF), comic book archives (CBZ), and lossless JPEG (JPEG-LS) images. The creator refers to the optimised automatic GIF optimizer in the most recent release as being best-in-class. The new neural-network colour quantizer is beneficial for image formats that rely on palettes.

Added enhancements to PhotoDemon 9.0 include:

- Image Resizer offers live interactive previews for 12 sophisticated resampling techniques.
- Support for Adobe Photoshop plugins built-in (8bf).
- Complete support of 3D LUTs (three dimensional Look-Up Tables).
- New effects include Gradient Flow, Bump Map, Droste, and Truchet Tiles.
- Improved tools for Crystallize and Stained Glass.
- A new dehaze tool to restore photos that have been “marred by haze or fog.”
- New user interface and improved tool performance curves.
- To “better match Photoshop’s implementation,” the Photo Filter tool has been redesigned.
