System.Drawing error on Save image from byte data

Question

Error converting a byte data to image in a UWP application

Tried to get the stream from the data and converting that to image but Error!

The error is:

system.drawing is not supported on this platform

 videoParser.Initialize(delegate (byte[] data)
 {
       using (MemoryStream mStream = new MemoryStream(data))
       {
           System.Drawing.Image img = System.Drawing.Image.FromStream(mStream);
           img.Save(@"D:/img.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
       }
       return DJISDKManager.Instance.VideoFeeder.ParseAssitantDecodingInfo(0, data);
 });

I want to save the image in jpeg format

Answer 1

you will need to use IFormFile

  private string SaveImage(Guid AdID, IFormFile Photo)
    {
        if (Photo != null)
        {
            string uploadFolder = Path.Combine(hostingEnvironment.WebRootPath, "AdsImages");
            string UniqueFileName = AdID.ToString() + "_" + Photo.FileName;
            string FilePath = Path.Combine(uploadFolder, UniqueFileName);
            Photo.CopyTo(new FileStream(FilePath, FileMode.Create));
            return UniqueFileName;
        }
        else
        {
            return null;
        }
    }

From the link @Amy shared, it seems that System.Drawing is not available for universal Windows Apps. If you only want to save the image from the data, you can first create a file and then write the bytes in it.

StorageFolder folder = await StorageFolder.GetFolderFromPathAsync(@"D:\");
StorageFile file = await folder.CreateFileAsync("img.jpg", CreationCollisionOption.ReplaceExisting);
await Windows.Storage.FileIO.WriteBytesAsync(file, data);
