Size increases after converting PPT to PDF

Aspose.Slides Product Family
#1

Hi
I am facing the issue while converting the PPT document to PDF using Aspose slides version # 17.8.0.0.
Here is my code snippet:

var tempfile = Path.GetTempFileName();
Presentation Presentation = new Presentation(InputFileName);
Aspose.Slides.Export.PdfOptions PdfSaveOptions = new Aspose.Slides.Export.PdfOptions();
PdfSaveOptions.Compliance = Aspose.Slides.Export.PdfCompliance.PdfA1b;

            using (var CompressedFileStream = new FileStream(tempfile, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None))
            {
                Presentation.Save(CompressedFileStream, Aspose.Slides.Export.SaveFormat.Pdf, PdfSaveOptions);

                long position = CompressedFileStream.Position;
                CompressedFileStream.Seek(0, System.IO.SeekOrigin.Begin);
                OutputFileBytes = new byte[position];
                CompressedFileStream.Read(OutputFileBytes, 0, (int)position);
            }

@Muddassir_Awan,

I have observed the issue shared by you and suggest you to please try using Aspose.Slides for .NET 18.6 on your end. If there is still an issue then please share the working sample project along with source and generated output. We will be able to investigate the issue further on our end on provision of requested information.

I have updated the aspose.slides version to 18.6.0.0.
Using Aspose.slides version # 17.8.0.0 the size changed from 763KB to 3MB and after updating to version 18.6.0.0 the size changes from 763KB to 2MB.
Can you check the issue with above code snippet as the PPT document is not allowed to be uploaded on this forum or you can suggest me another way to attach the PPT document

The document is placed at the following link:

Following is the working sample code with aspose.slides version 18.6
string InputFileName = “D://SourceFile.ppt”;
byte[] documentBytes = File.ReadAllBytes(InputFileName);
File.WriteAllBytes(“D://SourceFile.ppt”, documentBytes);

        byte[] OutputFileBytes = null;
        var tempfile = Path.GetTempFileName();
        Presentation Presentation = new Presentation(InputFileName);
        Aspose.Slides.Export.PdfOptions PdfSaveOptions = new Aspose.Slides.Export.PdfOptions();
        PdfSaveOptions.Compliance = Aspose.Slides.Export.PdfCompliance.PdfA1b;

        using (var CompressedFileStream = new FileStream(tempfile, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None))
        {
            Presentation.Save(CompressedFileStream, Aspose.Slides.Export.SaveFormat.Pdf, PdfSaveOptions);

            long position = CompressedFileStream.Position;
            CompressedFileStream.Seek(0, System.IO.SeekOrigin.Begin);
            OutputFileBytes = new byte[position];
            CompressedFileStream.Read(OutputFileBytes, 0, (int)position);
        }

        File.WriteAllBytes("D://ConvertedPDF.pdf", OutputFileBytes);
        Console.WriteLine("Converted file is placed at D://ConvertedPDF.pdf");
        Console.ReadLine();
