Here is my sample program:

using HeyRed.ImageSharp.Heif.Formats.Avif;
using HeyRed.ImageSharp.Heif.Formats.Heif;
using SixLabors.ImageSharp.Formats;


var files = Directory.GetFiles(@"C:\Users\myuser\Downloads\");
var types = new List<string>() { ".jpg", ".jpeg", ".png", ".heic" };

var options = new DecoderOptions()
{
    Configuration = new Configuration(
        new AvifConfigurationModule(),
        new HeifConfigurationModule()
        )
};

foreach (var file in files.Where(f => f.Contains("7B44F_bol.heic")))
{
    var ext = Path.GetExtension(file);
    if (types.Contains(ext))
    {
        Console.WriteLine(file);
        try
        {
            var image = Image.Load(options , file);
            Console.WriteLine(image.Size.ToString());
        }
        catch (Exception ex)
        {
            Console.WriteLine($"{file} error {ex.Message}");
        }
    }
}

Console.ReadLine();

Unable to convert heif to jpg taken by iPhone 15 pro

When trying to convert heif images (taken with iPhone 15 pro) to jpg format, we get an error
Invalid input: Unspecified: Metadata not correctly assigned to image

Code snippet which throw an exception

private static async Task<Stream> EditImageInMemoryAsync(Stream orignalImage, Action<IImageProcessingContext> opereation, IImageFormat format)
        {
            var modifiedImage = new MemoryStream();
            using var image = await Image.LoadAsync(orignalImage);
            image.Mutate(opereation);
            image.Save(modifiedImage, format);
            modifiedImage.Position = 0;
            orignalImage.Position = 0;
            return modifiedImage;
}

Similar issue were fixed in this package.

bad-images.zip - zip file with images. With these images we get an error.

libheif not found WSA/Android ImageSharp

Thanks for this library, very helpful for what I am working on.

I am trying to load an HEIC image using ImageSharp using this library. It works on windows but when I try to load it on android (I am using WSA, haven't gotten a chance to test on actual device but I would imagine it being the same), I get libheif not found.

I have installed both 'LibHeif.Native.win-x64' and 'LibHeif.Native.linux-x64'. for some reason 'LibHeif.Native' give me errors so I had install both separately.
