Are there any examples that uses SkiaSharp to save and manipulate the PDF image?

[MarioGK]

I tried to search an example that uses SkiaSharp to manipulate images instead of System.Drawings because i am using linux.

public static (byte[] content, int width, int height) ToImage(this byte[] fileBytes, int page = 0)
    {
        var docReader = DocLib.Instance.GetDocReader(fileBytes,DefaultPageDimensions);
        var pageReader = docReader.GetPageReader(page);
        
        var image = pageReader.GetImage();

        if (image == null)
        {
            throw new Exception("Could not find image in PDF");
        }
        
        var width = pageReader.GetPageWidth();
        var height = pageReader.GetPageHeight();

        return (image, width, height);
    }

    public static SKBitmap ToSkiaImage(this byte[] fileBytes, int page = 0)
    {
        var (imageContent, width, height) = fileBytes.ToImage(page);

        var bitmap = new SKBitmap(width, height);
        
        var array = new byte[bitmap.RowBytes * bitmap.Height];
        for (var i = 0; i < imageContent.Length; i++)
        {
            var color = new SKColor(imageContent[i]);
            var num = i % width;
            var num2 = i / width;
            array[bitmap.RowBytes * num2 + 4 * num] = color.Blue;
            array[bitmap.RowBytes * num2 + 4 * num + 1] = color.Green;
            array[bitmap.RowBytes * num2 + 4 * num + 2] = color.Red;
            array[bitmap.RowBytes * num2 + 4 * num + 3] = color.Alpha;
        }

        var pixels = bitmap.GetPixels();
        Marshal.Copy(array, 0, pixels, array.Length);
        
        return bitmap;
    }

This is as far as i got.

    public static SKBitmap ToSkiaImage(this byte[] fileBytes, int page = 0)
    {
        var (imageContent, width, height) = fileBytes.ToImage(page);
        var memoryStream = new MemoryStream(imageContent);
        var skData = SKData.Create(memoryStream);
        var bitmap = SKBitmap.Decode(skData, new SKImageInfo(width, height, SKColorType.Bgra8888));
        
        return bitmap;
    }

I tried with this method as well, and the bitmap return null

Not far from my working solution

        public static SKBitmap ToSkiaImage(byte[] bytes, int width, int height)
        {
            var bmp = new SKBitmap(new SKImageInfo(width, height,SKColorType.Bgra8888));
            
            Marshal.Copy(bytes, 0, bmp.GetPixels(), bytes.Length);

            return bmp;
        }
