✅ Skiarsharp - Bestway to check if image is landscape or portrait mode.

Actually my problem: an image with 4000x6000 going to landscape. But image like 845x852 won't. First approach I saw is width > height = landscape. What is the best way I can check if is portrait or landscape image?

        private bool TryProcessOriginalFile(string path)
        {
            using var stream = File.OpenRead(Path.Combine(path, "original"));
            var bmpLossless = SKBitmap.Decode(stream);

            if (bmpLossless == null)
            {
                return false;
            }
            //Only using it isnt trustful 
            if (bmpLossless.Width > bmpLossless.Height)
            {
                bmpLossless = RotateLandscapeToPortrait(bmpLossless);
            }

            var outPathJpg = Path.Combine(path, "original.jpg");
            using (var outFileJpg = new FileStream(outPathJpg, FileMode.Create))
            {
                bmpLossless.Encode(SKEncodedImageFormat.Jpeg, 70).SaveTo(outFileJpg);
            }
            bmpLossless.Dispose();
            return true;
        }

    private static SKBitmap RotateLandscapeToPortrait(SKBitmap bmpLossless)
        {
            var rotated = new SKBitmap(bmpLossless.Height, bmpLossless.Width);
            using (var canvas = new SKCanvas(rotated))
            {
                canvas.Clear();
                canvas.Translate(0, bmpLossless.Width);
                canvas.RotateDegrees(-90);
                canvas.DrawBitmap(bmpLossless, new SKPoint());
            }

            return rotated;
        }

        private bool TryProcessOriginalFile(string path)
        {
            using var stream = File.OpenRead(Path.Combine(path, "original"));
            var bmpLossless = SKBitmap.Decode(stream);

            if (bmpLossless == null)
            {
                return false;
            }
            //Only using it isnt trustful 
            if (bmpLossless.Width > bmpLossless.Height)
            {
                bmpLossless = RotateLandscapeToPortrait(bmpLossless);
            }

            var outPathJpg = Path.Combine(path, "original.jpg");
            using (var outFileJpg = new FileStream(outPathJpg, FileMode.Create))
            {
                bmpLossless.Encode(SKEncodedImageFormat.Jpeg, 70).SaveTo(outFileJpg);
            }
            bmpLossless.Dispose();
            return true;
        }

    private static SKBitmap RotateLandscapeToPortrait(SKBitmap bmpLossless)
        {
            var rotated = new SKBitmap(bmpLossless.Height, bmpLossless.Width);
            using (var canvas = new SKCanvas(rotated))
            {
                canvas.Clear();
                canvas.Translate(0, bmpLossless.Width);
                canvas.RotateDegrees(-90);
                canvas.DrawBitmap(bmpLossless, new SKPoint());
            }

            return rotated;
        }

{
  return (sales, sales.Count());
}
obs: I cut off some lines
