The developers of the open source photo editor PhotoDemon have released PhotoDemon 9.0 after two years of development. The new release features user interface improvements, support for new image formats, reduced resource usage, built-in support for Adobe Photoshop plugins and more.

PhotoDemon 9.0​

One of the main improvements of the new PhotoDemon is that it uses less resources than the old version. On cold start, for instance, it is using 12% less memory than the previous version.

Users who upgrade from an earlier version of PhotoDemon to version 9 may notice the revised interface right away. Tools have moved, and popular settings appear directly on the toolbar, with the rest appearing as flyout panels. According to the developer, the new user interface takes up "less than half of the vertical space of the old design" without sacrificing functionality.

The UI is still designed to work with different display resolutions, including classic resolutions such as 1024x768. The redesign gives more room for photos that are opened in the editor.

The photo editors selection tools have worked well in previous versions. The new release introduces support for multiple selections. Selections may be combined using Add, Subtract and Intersect, and the last selection remains editable even when multiple selections are active.

Another new feature is the content-aware fill tool, which is also called smart object removal or inpainting. Users may select Edit > Content-aware fill, or Select > Heal selected area, to use it. The tool works automatically but includes preferences and tweaking options to customize the operation.

The tool does not require an Internet connection or artificial intelligence. In fact, running the tool multiple times may produce better results because of that.

PhotoDemon 9.0 adds support for new image formats. The new release has import and export support for PSP images, AVIF and animated WebP images. AVIF support is available, but the required encoder and decoder apps do not ship with the program because of their sizes. First time a user loads or saves an AVIF file, the required data is downloaded. Import support is now available for XCF (GIMP), SVG and SVGZ images.

Last but not least, PhotoDemon 9.0 supports lossless JPEG (JPEG-LS), comic book archives (CBZ), Symbian images (MBM and AIF), and lossless "quite OK" (QOI) images.

The latest release includes an optimized automatic GIF optimizer, which the developer calls best-in-class. Image formats that rely on palettes benefit from the new neural-network color quantizer.

Other improvements in PhotoDemon 9.0:
  • Image Resizer supports 12 advanced resampling modes with live interactive previews.
  • Built-in support for Adobe Photoshop plugins (8bf).
  • Full support for 3D LUTs (three dimensional Look-Up Tables).
  • New Effects: Bump Map, Droste, Truchet Tiles, Animation menu and Gradient Flow.
  • Improved Stained Glass and Crystallize tools.
  • New Dehaze tool to recover photos "marred by haze or fog".
  • Curves tool performance improvements and new user interface.
  • Photo Filter tool has been redesigned to "better match Photoshop's implementation".
A full list of changes, with lots of examples, is available on the official PhotoDemon website.

Coincidentally, I found out about this software yesterday on MajorGeeks and am currently trying it out. What surprised me was the ability to display layered images in .psd and .xcf formats while preserving the mask. There aren't many software that can do that.:)(y)
