Release version 1.0.6. Changes: Support loading images that do not have an image size property for the alpha channel Fixed the position of the Quality slider label Reject files that have certain invalid layouts

Release version 1.0.1. Changes: Allow the chroma subsampling mode to be configured when saving (4:2:0, 4:2:2 or 4:4:4) Add forum and GitHub links to the UI Upgraded to libheif version 1.8.0

The plugin is only GPL because that is the license used by the x265 encoder, both libheif and the libde265 decoder are LGPL. It would be nice if there was a free / non-GPL HEVC encoder available, but the requirement for HEVC patent royalties makes that unlikely.

Release version 1.0.5. Changes: Changed the Compression Mode header to Compression Speed. Changed the default compression speed to Fast. Renamed the Normal compression speed to Medium. Fixed a bug when reading empty AVIF strings.

Each pixel in Paint.NET uses 4 bytes.

Release version 1.0.4. Changes: Remove the EXIF orientation tag when loading Ignore any ICC profile in the EXIF data Do not read beyond the stated size of any HEIF box Add integer overflow checks to a few calculations

This plugin tags any image that does not have an existing color profile as sRGB when saving the EXIF data to the file, Microsoft's decoder may be telling WIC that there is a sRGB profile based on that tag. This plugin does not use the limited color range (16-235), it always uses the full RGB color range (0-255).

Release version 1.0.3. Changes: Fix the property association box size for images with alpha Add forum and GitHub links to the UI

The color profile is being exported, so that may just be another bug in Microsoft's AVIF codec. It looks like libavif is failing to load the property associations for the alpha channel image.

Paint.NET cannot be installed to an external disk.

Release version 1.0.6. Changes: Throw an exception for unsupported image types. Reduced memory usage when loading.

Reduced memory usage when loading ABR v6+ files, file version updated to 1.3.2.0.

This plugin allows HEIC images to be loaded and saved with transparency, and adds a few more options when saving. It replaces Paint.NET's built-in HEIC support. This plugin may produce smaller files than Microsoft's encoder for grayscale images. For most color images Microsoft's encoder is faster and produces smaller files. Compatibility: 4.3.12+ Installation: 1. Close Paint.NET. 2. Place HeicFileTypePlus.dll, HeicFileTypePlusIO_ARM64.dll, HeicFileTypePlusIO_x86.dll and HeicFileTypePlusIO_x64.dll in the Paint.NET FileTypes folder which is usually located in one the following locations depending on the Paint.NET version you have installed. Classic: C:\Program Files\Paint.NET\FileTypes Microsoft Store: Documents\paint.net App Files\FileTypes Portable: <Paint.NET folder>\FileTypes 3. Disable the built-in Paint.NET HEIC support Classic / Microsoft Store Open the Windows Run dialog (Start > Run or Windows Key + R) Type paintdotnet:/set:FileTypes/BuiltInHEICFileTypeEnabled=false and press the Enter key Portable Open a command prompt in the folder that Paint.NET is located in. Type paintdotnet.exe /set:FileTypes/BuiltInHEICFileTypeEnabled=false and press the Enter key 4 Restart Paint.NET.

Not as far as I am aware. The OP mentioned that this occurs when creating a new layer, which would be a Paint.NET issue. DDSFileTypePlus preserves the RGB color values of transparent pixels when saving, due to the fact that some games use the alpha channel for things other than transparency. It would be easy to add a "Preserve color of transparent pixels" checkbox to allow this behavior to be disabled, transparent pixels would be set to black when it is unchecked.

Not true, the webpmux sample utility can be used to add and remove WebP metadata. But I do not think that either the Microsoft or Google WIC decoder supports reading the EXIF/XMP metadata. That is a limitation of the VP8 compression format that WebP uses, I have no idea why a video compression format released in 2008 would only use 14 bits for the image width and height.

Release version 1.0.2 Changes: Changed the FileType name to AV1 (AVIF) Fixed an issue with preserving the AVIF color conversion data Disable row multi-threading when encoding with a single thread Reduced the native DLL size Fixed a potential memory leak

That is actually version 3.36, the background was changed to #c0c0c0 in that version. Paint.NET 3.36 is almost 12 years old, it is no longer supported.

That file looks like it is compressed or encrypted, you need to decode it before the image can be edited.

No, that is a different RAW file plugin. What do you mean by layers? All RAW formats that I am aware of contain only a single image. If you are referring to the individual color channels, Paint.NET does not currently have that feature.

I assume that the OP downloaded them from Simon's website, https://www.isimonbrown.co.uk/plugin-pack/. The plugin pack download page suggests that users to try the 'Detect plugin problems' utility if the plugins do not work.

Released version 0.2.0. Changes: Added support for G'MIC filters that produce multiple output images. Renamed the Output property to OutputImages and changed the return type to IReadOnlyList<PdnGmicBitmap>. The host application name is now set to paintdotnet. Reduced memory usage when editing grayscale images. The GmicSharpNative binaries are now located in a folder.

An identical problem was reported in the following thread: https://forums.getpaint.net/topic/115687-problem-updating-to-428/

It is one of the selection modes in the toolbar, see https://www.getpaint.net/doc/latest/SelectionTools.html#13.

WebP and AV1 are different formats, so it is not surprising that there would be a size difference with the same settings.
