4.2.2 beta build 7186

This update has some goodies in it. AV1 (*.avif) support has been added, DirectDraw Surface (*.dds) support has been completely upgraded by way of bundling @null54‘s excellent DDSFileTypePlus plugin, and there are some great performance improvements and bug fixes.

To get this update, make sure you have “Also check for pre-release (beta) versions” enabled in Settings, and then click on the Check Now button.


You can also download this by heading over to the forum where I’ve put a direct download link.

Change log:

  • New: AV1 (*.avif) images can now be opened (saving is not supported). Windows 10 v1809+ and Microsoft’s AV1 Codec are required (download:
  • New: DirectDraw Surface (*.dds) support has been greatly improved due to bundling @null54‘s DDSFileTypePlus plugin. All DX10/DX11 formats should now be supported (e.g. BC4, BC5, BC6H, BC7), and encoding (saving) will make use of the GPU to greatly improve performance. Note that it’s not longer necessary to use the “.dds2” file extension.
  • Improved: Startup performance has been improved
  • Fixed: EXIF metadata of type Float and Double are now supported. This ensures GeoTIFF metadata is preserved.
  • Fixed: Opening an image should no longer flicker because the transparency checkerboard was being drawn first
  • Fixed: TGA images that are 16-bit with 1-bit alpha with a zero’d out alpha channel are now treated as opaque. This allows images from 5CC Map Maker (for Close Combat modding) to work. Thanks @null54 for the fix!
  • Fixed: JPEG XR’s file extensions (*.jxr, *.wdp, *.wmp) are now registered with Explorer
  • Fixed: Pasting images that use RGB pixel ordering should now work (this affects PaintTool SAI)

    Cool stuff, thanks. Any chance of getting support for .bmp files wider than 65535 being supported, as far as moving or copying into that extended area is concerned?

      • MikeBramm says:

        Bitmaps that wide are supported by a number of programs. The best program I’ve found so far to edit images that wide is GIMP. I usually use PAINT.NET to edit my images, and it can load and save images that are wider than 65535 pixels, but it just doesn’t support copying or moving across the 65535 boundary. I have a bitmap font that is 110925 pixels wide by 1024 pixels tall if you would like me to send it do you for testing.

          I think the limitation I’m thinking of is that BMPs literally can’t have more than 4GB of pixel data due to the header using a 32-bit DWORD for a byte count somewhere. But you’re right, that shouldn’t limit any axis to any specific length.

          I have been making progress on uncapping PDN’s ability to work with large and huge images. There were some very important performance fixes that went in for the 4.2 release, for instance, along with the ability to open much larger images (like PNGs especially) than were previously possible.

          Yeah, go ahead and send me the image. Use the e-mail at
