A Paint.NET filetype plugin that allows HEIC images to be loaded and saved with transparency.

pdn-heicfiletype-plus

A Paint.NET filetype plugin that allows HEIC images to be loaded and saved with transparency.

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.

Paint.NET Version	FileTypes Folder Location
Classic	C:\Program Files\Paint.NET\FileTypes
Microsoft Store	Documents\paint.net App Files\FileTypes

3. Disable the built-in Paint.NET HEIC support

• Classic / Microsoft Store
  1. Open the Windows Run dialog (Start > Run or Windows Key + R)
  2. Type paintdotnet:/set:FileTypes/BuiltInHEICFileTypeEnabled=false and press the Enter key
• Portable
  1. Open a command prompt in the folder that Paint.NET is located in.
  2. Type paintdotnet.exe /set:FileTypes/BuiltInHEICFileTypeEnabled=false and press the Enter key

4. Restart Paint.NET.

pdn-heicfiletype-plus's Issues

File size when saving is much larger than original

My Samsung Galaxy S21 takes photos in heic format. On average, they are around 1.5 MB large.
If I open them in paint.net with this plugin, then save them again, whether I change anything or not, the saved size is about 5 MB.
In order to get a similar size as the original, I have to put the vague quality setting at around 60%.
Is this potentially a bug or something that could be improved?
Is this all related to the quality setting?
Is there any way to see the quality setting of the original heic image?
Is there any way to edit a heic image in a way that preserves both the original quality and the original file size? For example, if the only change I am making are cropping, I feel like the image shouldn't have to lose quality and should also decrease in file size or stay the same size at worst.

Add format detection for files with the wrong extension

It appears to be fairly common for JPEG files (and possibly other formats?) to be misidentified with a HEIC file extension.
See issue #1 and #3 for examples of JPEG images with a HEIC file extension.

The format detection can be run on the error code path, when libheif returns heif_error_Invalid_input with heif_suberror_No_ftyp_box.
It would consist of checking the first few bytes of the file for the magic number signature of different image formats.
If the image format is supported by GDI+, it will be loaded using Document.FromGdipImage.

All JPEG files start with the signature FFD8, the 'Start of Image' marker.

The plugin works well in paint.net, but I tried in my app and got InvalidFile

I tried this:

	HEIFInterface			heifInterface;

	if (heifInterface.isValid())
	{
		heif_context	*context;

		context = heifInterface.createContext();

		if (context)
		{
			IOCallbacks	fileIO;
			Status		stat;

			_myFile = file;
			fileIO.GetPosition = MyGetPosition;
			fileIO.GetSize = MyGetSize;
			fileIO.Read = MyRead;
			fileIO.Seek = MySeek;
			fileIO.Write = MyWrite;

			stat = heifInterface.loadFileIntoContext(context, &fileIO);

but stat gives always an InvalidFile.
Do you know why?

files created with 4:4:4 and 4:2:2 subsampling cannot be opened

Saving files with 4:4:4 and 4:2:2 chroma subsampling creates files which cannot be opened by paint.net itself.
This is irrespective of any other settings, I think I tested all combinations. Using newest version of paint.net (4.3.11).

I also attached a sample file, which was a newly created 1200x900 of white: Untitled.zip

HeicFileTypePlus 1.0.5.0 & paint.net 4.3.4 does not work

Default should not be SSIM or PSNR tuning, it should be the "untuned" setting

Following the x265 manual on the tune parameter (https://x265.readthedocs.io/en/stable/presets.html#tuning) it seems that SSIM and PSNR should not be the default setting for this plugin:

The psnr and ssim tune options disable all optimizations that sacrafice metric scores for perceived visual quality (also known as psycho-visual optimizations). By default x265 always tunes for highest perceived visual quality but if one intends to measure an encode using PSNR or SSIM for the purpose of benchmarking

Also the "untuned" x265 misses from the dropdown, following the bold emphasised part from the quote this should be optimal for actual images.

Rename LICENSE..txt to LICENSE.txt for releases

No big deal, it's just me reached a LICENSE..txt when searching my disk for filenames that contains .., and reached here, and confirmed the releases really has a LICENSE..txt, although this repo has a LICENSE.txt.

You may want to fix this if there is no reason for a LICENSE..txt.
