How I can use the ImageSharp to convert Tiff to Jpeg?

[mugedegerliyurt]

I am trying to convert Tiff to Jpeg by using ImageSharp library, but I am having problem with the code part:

Subsample = JpegSubsample.Ratio444, // No chroma subsampling for highest quality
IgnoreMetadata = true // Strips all metadata

since it is not supported with the current version. Could you please help me how I can handle the problem? Thank you!

using System;
using System.IO;
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Processing;
using SixLabors.ImageSharp.Formats.Jpeg;
using SixLabors.ImageSharp.PixelFormats;

public class TiffToJpegConverter
{
public static void ConvertTiffToJpeg(string inputPath, string outputPath)
{
try
{
using (Image image = Image.Load(inputPath)) // Ensures image is loaded as RGB24
{
// Auto-orient to correct rotation
image.Mutate(x => x.AutoOrient());

            // Resize if image is too large 
            image.Mutate(x => x.Resize(new ResizeOptions
            {
                Size = new Size(2048, 2048),
                Mode = ResizeMode.Max
            }));
           
            // Save as JPEG with stripped metadata
            var encoder = new JpegEncoder
            {
                Quality = 90,
                Subsample = JpegSubsample.Ratio444, // No chroma subsampling for highest quality
                IgnoreMetadata = true // Strips all metadata
            };
           
            image.Save(outputPath, encoder);
        }
        Console.WriteLine($"Conversion successful: {outputPath}");
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error converting TIFF: {ex.Message}");
    }
}

public static bool IsImageValid(string imagePath)
{
    try
    {
        using (Image<Rgb24> image = Image.Load<Rgb24>(imagePath)) // Load as specific pixel format
        {
            return image.PixelType.BitsPerPixel == 24; // Ensure 24-bit RGB
        }
    }
    catch
    {
        return false; // Corrupted file
    }
}

}

I have no idea what you are actually asking? What is failing?

You should be able to decode a TIFF and encode in any of the available formats.

The JpegSubsample method isn't available in the library; do you know of any alternatives I can use? My issue isn't just converting TIFF to JPEG; I need the converted JPEG to meet certain standards for use with OpenAI services.
