Importing HDRI texture on. NET Android platform throws exception: 'Specified method is not supported'

[CeSun]

I guess it's because Stream on the Android platform doesn't support certain methods, and I've encountered similar issues using the SharpGLTF library before.

my code:

 public static Texture ImportTextureHdrFromStream(StreamReader streamReader, TextureImportSetting setting)
 {
 if (setting.FlipVertically)
 {
 StbImage.stbi_set_flip_vertically_on_load(1);
 }
 var imageResult = ImageResultFloat.FromStream(streamReader.BaseStream);
 if (setting.FlipVertically)
 {
 StbImage.stbi_set_flip_vertically_on_load(0);
 }
 if (imageResult != null)
 {
 var texture = new Texture
 {
 Width = (uint)imageResult.Width,
 Height = (uint)imageResult.Height,
 Channel = imageResult.Comp.ToTexChannel()
 };
 texture.IsGammaSpace = setting.IsGammaSpace;
 texture.HDRPixels = new(imageResult.Data);
 texture.IsHdrTexture = true;
 return texture;
 }
 throw new Exception("Load Texture error");
 }

The stream is from

new StreamReader(Activity.Assets.Open($"Resource/{Path}"));

When I make the following modifications, it can avoid this problem

 public static Texture ImportTextureHdrFromStream(StreamReader streamReader, TextureImportSetting setting)
 {
 MemoryStream ms = new MemoryStream();
 using (BinaryReader br = new BinaryReader(streamReader.BaseStream))
 {
 List<byte> buffer = new List<byte>();
 do
 {
 var data = br.ReadBytes(1024);
 if (data.Length <= 0)
 break;
 ms.Write(data);
 } while (true);
 }


 if (setting.FlipVertically)
 {
 StbImage.stbi_set_flip_vertically_on_load(1);
 }
 var imageResult = ImageResultFloat.FromStream(ms);
 if (setting.FlipVertically)
 {
 StbImage.stbi_set_flip_vertically_on_load(0);
 }
 if (imageResult != null)
 {
 var texture = new Texture
 {
 Width = (uint)imageResult.Width,
 Height = (uint)imageResult.Height,
 Channel = imageResult.Comp.ToTexChannel()
 };
 texture.IsGammaSpace = setting.IsGammaSpace;
 texture.HDRPixels = new(imageResult.Data);
 texture.IsHdrTexture = true;
 return texture;
 }
 throw new Exception("Load Texture error");
 }

It's known issue.
That's how its handled in the MonoGame(that used StbImageSharp): https://github.com/MonoGame/MonoGame/blob/97c029b72c1bbd853d147c89301d36c6f3b3e394/MonoGame.Framework/Platform/Graphics/Texture2D.StbSharp.cs#L23C1-L37C14
