How to create an uncompressed PDF file?

Tags: compressioncompression leveliText 7

During development testing, I'd prefer to create uncompressed, non-binary PDF files with iTextSharp so that I can check their internals easily. I can always convert the finished PDF with various utilities but that takes an extra step that would be comfortable to avoid. There are some places (e.g. PdfImage) where I can decide about compression level but I couldn't find anything about the compression used to output the individual PDF objects into the stream. Do you think this is possible with iTextSharp?

In iText 7 you can set the compression level to 0, which means no compression using WriterProperties class:

WriterProperties properties = new WriterProperties()
        .setCompressionLevel(CompressionConstants.NO_COMPRESSION);
PdfWriter writer = new PdfWriter(dest, properties);
PdfDocument pdfDoc = new PdfDocument(writer);
Document doc = new Document(pdfDoc);
doc.add(new Paragraph("Hello World!"));
doc.close();

In this case your PDF syntax streams won't be compressed.
