Hi all,

I am serching for Third party library for optimize means linerarize PDF.
not 3rd party application, it should be a DLL which can be used in C# code to optimize(linearize) pdf.

I know PDFTRON and BYTECOUNT but it costs more.
If anybody Knows lesser in price its gud.

Any idea using c# and iTextSharp can we compress pdf
Thanks in advance

Using iTextSharp is possible you need to set the version of PDF and then, try this

C#

Document doc = new Document(PageSize.A4, 50, 50, 25, 25);
PdfWriter writer = PdfWriter.GetInstance(doc, ms);
PdfContentByte contentPlacer;

writer.SetPdfVersion(PdfWriter.PDF_VERSION_1_5);

writer.CompressionLevel = PdfStream.BEST_COMPRESSION;
