ImageSharp.Heif
HEIF/AVIF decoder for ImageSharp
🚧 WIP. Some features(like encoder) is not implemented.
Use libheif-sharp for all features provided by libheif.
Install
via NuGet:
PM> Install-Package HeyRed.ImageSharp.Heif
Native libs for x64 Linux and Windows:
PM> Install-Package LibHeif.Native
Separate native packages:
PM> Install-Package LibHeif.Native.win-x64
PM> Install-Package LibHeif.Native.linux-x64
Usage
using System.IO;
using SixLabors.ImageSharp;
using HeyRed.ImageSharp.Heif.Formats.Heif;
using HeyRed.ImageSharp.Heif.Formats.Avif;
var decoderOptions = new DecoderOptions()
{
Configuration = new Configuration(
new AvifConfigurationModule(),
new HeifConfigurationModule())
};
using var image = Image.Load(decoderOptions, "/path/to/image.avif"); // or image.heic
// Do something with image
...Top level images
Note: libheif have some limitations
By default DecodingMode set to PrimaryImage, but if you want decode all top level images see example listed below:
var decoderOptions = new HeifDecoderOptions
{
DecodingMode = DecodingMode.TopLevelImages,
// MaxFrames option is also supported
GeneralOptions = new DecoderOptions
{
MaxFrames = 10,
}
};
using var inputStream = File.OpenRead("/path/to/image.avif"); // or image.heic
using var image = HeifDecoder.Instance.Decode(decoderOptions, inputStream);
// Saves all frames
for (int i = 0; i < image.Frames.Count; i++)
{
image.Frames
.CloneFrame(i)
.SaveAsJpeg($"frame{i}.jpg");
}
