Image to PDF conversion is not correct

Aspose.PDF Product Family

Hi Support,
I am facing an issue with Aspose.PDF 21.6.0.0 while converting image to PDF. In my scenario I have a PNG image which is converted to PDF after removing image transparency but in resultant PDF the image is very small.
I have attached the working sample along with the document converted via Adobe:

Could you please guide me in this scenario.
Regards,

Hi @asad.ali
Please find the below code snippet:
byte[] OutputFileBytes = null;
string tempfile = Path.GetRandomFileName();
Aspose.Pdf.Document PdfDocument = new Aspose.Pdf.Document();
Aspose.Pdf.Page Sec = PdfDocument.Pages.Add();

        Bitmap TempImage = null;

        byte[] bitmapData = File.ReadAllBytes(@"..\..\..\Files\Image.png");
        Image _image = System.Drawing.Image.FromStream(new MemoryStream(bitmapData));
        TempImage = new Bitmap(_image);

        if (TempImage.Width > TempImage.Height)
        {
            Sec.PageInfo.IsLandscape = true;
        }
        else
        {
            Sec.PageInfo.IsLandscape = false;
        }

        Aspose.Pdf.Image Image = new Aspose.Pdf.Image
        {
            FixWidth = TempImage.Width - Sec.PageInfo.Margin.Left - Sec.PageInfo.Margin.Right,
            FixHeight = TempImage.Height - Sec.PageInfo.Margin.Top - Sec.PageInfo.Margin.Bottom
        };
        Sec.Paragraphs.Add(Image);

        Image.ImageStream =RemoveTransparency(new MemoryStream(bitmapData));

        using (FileStream CompressedFileStream = new FileStream(tempfile, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None))
        {
            PdfDocument.Save(CompressedFileStream);
            OutputFileBytes = new byte[CompressedFileStream.Length];
            CompressedFileStream.Seek(0, System.IO.SeekOrigin.Begin);
            CompressedFileStream.Read(OutputFileBytes, 0, (int)CompressedFileStream.Length);
        }

private static Stream RemoveTransparency(Stream fileStream)
       {
           Stream stream = new MemoryStream();
           fileStream.Seek(0, System.IO.SeekOrigin.Begin);
           using (Bitmap src = new Bitmap(fileStream))
           {
               Bitmap target = new Bitmap(src.Size.Width, src.Size.Height);
               Graphics g = Graphics.FromImage(target);
               g.Clear(System.Drawing.Color.White);
               g.CompositingMode = System.Drawing.Drawing2D.CompositingMode.SourceOver;
               g.DrawImage(src, 0, 0);
               target.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
           }
           return stream;
       }

Please find the image, resultant file and document converted from PDF attached with this ticket.
