DocToPDFConverter class is responsible for converting a Word document into PDF. The following code snippet illustrates how to convert a Word document into PDF document.

C# [Cross-platform]

// Open the file as Stream.
FileStream docStream = new FileStream(@"Template.docx", FileMode.Open, FileAccess.Read);
//Loads file stream into Word document.
WordDocument wordDocument = new WordDocument(docStream, Syncfusion.DocIO.FormatType.Automatic);
//Instantiation of DocIORenderer for Word to PDF conversion.
DocIORenderer render = new DocIORenderer();
//Converts Word document into PDF document.
PdfDocument pdfDocument = render.ConvertToPDF(wordDocument);
//Releases all resources used by the Word document and DocIO Renderer objects.
render.Dispose();
wordDocument.Dispose();

//Save the document into stream.
MemoryStream stream = new MemoryStream();
pdfDocument.Save(stream);
//Close the document.
pdfDocument.Close(true);

C# [Windows-specific]

//Load an existing Word document.
WordDocument wordDocument = new WordDocument("Template.docx", FormatType.Docx);
//Initialize chart to image converter for converting charts during Word to pdf conversion.
wordDocument.ChartToImageConverter = new ChartToImageConverter();
//Create an instance of DocToPDFConverter.

Converting TIFF to PDF

Converting multi page TIFF to PDF

Multi frame TIFF image can be converted to PDF document using PdfBitmap class. This can be done by accessing each frame of the multi frame TIFF image and rendering it in each page of the PDF document.

The code snippet to illustrate the same is given below.

C# [Cross-platform]

//Create a new PDF document
PdfDocument document = new PdfDocument();

//Load the multi frame TIFF image from the disk
FileStream imageStream = new FileStream("image.tiff", FileMode.Open, FileAccess.Read);
PdfTiffImage tiffImage = new PdfTiffImage(imageStream);
//Get the frame count
int frameCount = tiffImage.FrameCount;
//Access each frame and draw into the page
for (int i = 0; i < frameCount; i++)
{
	//Add a section to the PDF document
	PdfSection section = document.Sections.Add();
	//Set page margins
	section.PageSettings.Margins.All = 0;
	tiffImage.ActiveFrame = i;
	//Create a PDF unit converter instance
	PdfUnitConvertor converter = new PdfUnitConvertor();
	//Convert to point
	Syncfusion.Drawing.SizeF size = converter.ConvertFromPixels(tiffImage.PhysicalDimension, PdfGraphicsUnit.Point);
	//Set page orientation
	section.PageSettings.Orientation = (size.Width > size.Height) ? PdfPageOrientation.Landscape : PdfPageOrientation.Portrait;
	//Set page size
	section.PageSettings.Size = size;
	//Add a page to the section
	PdfPage page = section.Pages.Add();
	//Draw TIFF image into the PDF page
	page.Graphics.DrawImage(tiffImage, Syncfusion.Drawing.PointF.Empty, size);
}

//Creating the stream object
MemoryStream stream = new MemoryStream();
//Save the document as stream
document.Save(stream);
//Close the document
document.Close(true);

C# [Windows-specific]

//Create a PDF document
PdfDocument pdfDocument = new PdfDocument();

//Load multi frame TIFF image
PdfBitmap tiffImage = new PdfBitmap("image.tiff");
//Get the frame count
int frameCount = tiffImage.FrameCount;
//Access each frame and draw into the page
for (int i = 0; i < frameCount; i++)
{
	tiffImage.ActiveFrame = i;
	//Add a section to the PDF document
	PdfSection section = pdfDocument.Sections.Add();
	//Set page margins
	section.PageSettings.Margins.All = 0;
	//Create a PDF unit converter instance
	PdfUnitConvertor converter = new PdfUnitConvertor();
	//Convert to point
	SizeF size = converter.ConvertFromPixels(tiffImage.PhysicalDimension, PdfGraphicsUnit.Point);
	//Set page orientation
	section.PageSettings.Orientation = (size.Width > size.Height) ? PdfPageOrientation.Landscape : PdfPageOrientation.Portrait;
	//Set page size

NOTE

1. Essential® PDF supports converting TIFF to PDF with Syncfusion.Pdf.Imaging.Portable assembly reference in ASP.NET Core.

Compression in monochrome images

Essential® PDF supports JBIG2 compression for best compression of monochrome images.

Refer the below code snippet to draw a single frame monochrome TIFF image with JBIG2 compression using EncodingType Enum.

C# [Cross-platform]

//PDF doesn't support compressing monochrome images C#.NET Cross platforms.

C# [Windows-specific]

//Create a PDF document
PdfDocument pdfDocument = new PdfDocument();
//Add a page
PdfPage page = pdfDocument.Pages.Add();

//Load single frame TIFF image
PdfBitmap tiffImage = PdfImage.FromFile("image.tiff") as PdfBitmap;
//Set encode type
tiffImage.Encoding = EncodingType.JBIG2;
//Draw an image
page.Graphics.DrawImage(tiffImage, 0, 0, page.GetClientSize().Width, page.GetClientSize().Height);

//Save and close the document
pdfDocument.Save("Sample.pdf");
pdfDocument.Close(true);

VB.NET [Windows-specific]

'Create a PDF document
Dim pdfDocument As New PdfDocument()
'Add a page
Dim page As PdfPage = pdfDocument.Pages.Add()

'Load single frame TIFF image
Dim tiffImage As PdfBitmap = TryCast(PdfImage.FromFile("image.tiff"), PdfBitmap)
'Set encode type
tiffImage.Encoding = EncodingType.JBIG2
'Draw an image
page.Graphics.DrawImage(tiffImage, 0, 0, page.GetClientSize().Width, page.GetClientSize().Height)

'Save and close the document
pdfDocument.Save("Sample.pdf")
pdfDocument.Close(True)

You can download a complete working sample from GitHub.

NOTE

1. Currently the JBIG2Decode compression is supported only in lossy mode and also only single frame TIFF images are supported.
2. By default, all monochrome images will be compressed in CITTT4 compression.

Converting XPS document to PDF

The XPS (XML Paper Specification) document format is a fixed document format which consists of structured XML markup that defines the layout of a document and the visual appearance of each page, along with rendering rules for distributing, archiving, rendering, processing and printing the documents.

//Open the XPS file as stream.
FileStream fileStream = new FileStream("Input.xps", FileMode.Open, FileAccess.ReadWrite);
//Convert the XPS to PDF.
PdfDocument document = converter.Convert(fileStream);

//Creating the stream object.
MemoryStream stream = new MemoryStream(); 
//Save the document into stream.
document.Save(stream); 
//Close the documents.
document.Close(true);

C# [Windows-specific]

//Create converter class
XPSToPdfConverter converter = new XPSToPdfConverter();
//Convert the XPS to PDF
