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.

//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

DocToPDFConverter converter = new DocToPDFConverter();

//Convert Word document into PDF document

PdfDocument pdfDocument = converter.ConvertToPDF(wordDocument);

//Save the PDF file

pdfDocument.Save("WordtoPDF.pdf");

//Close the instance of document objects

pdfDocument.Close(true);

wordDocument.Close();
'Load an existing Word document

Dim wordDocument As 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

Dim converter As New DocToPDFConverter()

'Convert Word document into PDF document

Dim pdfDocument As PdfDocument = converter.ConvertToPDF(wordDocument)

'Save the PDF file

pdfDocument.Save("WordtoPDF.pdf")

'Close the instance of document objects

pdfDocument.Close(True)

wordDocument.Close()
// 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);

stream.Position = 0;

//Close the documents

pdfDocument.Close(true);

//Defining the ContentType for pdf file

string contentType = "application/pdf";

//Define the file name

string fileName = " WordtoPDF.pdf";

//Creates a FileContentResult object by using the file contents, content type, and file name

return File(stream, contentType, fileName);
//Load the Word document as stream

Stream docStream = typeof(App).GetTypeInfo().Assembly.GetManifestResourceStream("Sample.Assets.Template.docx");

//Load the 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 memory stream

MemoryStream stream = new MemoryStream();

pdfDocument.Save(stream);

stream.Position = 0;

//Close the document 

pdfDocument.Close();

//Save the stream into pdf file

//The operation in Save under Xamarin varies between Windows Phone, Android and iOS platforms. Please refer PDF/Xamarin section for respective code samples

if (Device.OS == TargetPlatform.WinPhone || Device.OS == TargetPlatform.Windows)
{
    Xamarin.Forms.DependencyService.Get<ISaveWindowsPhone>().Save("WordtoPDF.pdf", "application/pdf", stream);
}
else
{
    Xamarin.Forms.DependencyService.Get<ISave>().Save("WordtoPDF.pdf", "application/pdf", stream);
}

Note:

  • Initializing the ChartToImageConverter is mandatory to convert the charts present in the Word document to PDF. Otherwise the charts will not be exported to the converted PDF.
  • ChartToImageConverter is supported from .NET Framework 4.0 onwards.
  • Total number of pages may vary based on unsupported elements in the converted PDF document when compare to Word document.

Customizing the Word document to PDF conversion

Essential DocIO allows you to customize the Word to PDF conversion with the below options:

  • Allows to determine the quality of the charts in the converted PDF
  • Allows to determine the quality of the JPEG images in the converted PDF
  • Allows to reduce the Main Memory usage in Word to PDF conversion by reusing the identical images.
//Loads an existing Word document

WordDocument wordDocument = new WordDocument("Sample_Image.docx", FormatType.Docx);

//Initialize chart to image converter for converting charts during Word to pdf conversion

wordDocument.ChartToImageConverter = new ChartToImageConverter();

//Set the scaling mode for charts

wordDocument.ChartToImageConverter.ScalingMode = ScalingMode.Normal;

//create an instance of DocToPDFConverter - responsible for Word to PDF conversion

DocToPDFConverter converter = new DocToPDFConverter();

//Set the image quality

converter.Settings.ImageQuality = 100;

//Set the image resolution

converter.Settings.ImageResolution = 640;

//Set true to optimize the memory usage for identical images

converter.Settings.OptimizeIdenticalImages = true;

//Convert Word document into PDF document

PdfDocument pdfDocument = converter.ConvertToPDF(wordDocument);

//Save the PDF file to file system

pdfDocument.Save("WordtoPDF.pdf");

//close the instance of document objects

pdfDocument.Close(true);

wordDocument.Close();
'Loads an existing Word document

Dim wordDocument As New WordDocument("Sample_Image.docx", FormatType.Docx)

'Initialize chart to image converter for converting charts during Word to pdf conversion

wordDocument.ChartToImageConverter = New ChartToImageConverter()

'Set the scaling mode for charts

wordDocument.ChartToImageConverter.ScalingMode = ScalingMode.Normal

'create an instance of DocToPDFConverter - responsible for Word to PDF conversion

Dim converter As New DocToPDFConverter()

'Set the image quality

converter.Settings.ImageQuality = 100

'Set the image resolution

converter.Settings.ImageResolution = 640

'Set true to optimize the memory usage for identical images

converter.Settings.OptimizeIdenticalImages = True

'Convert Word document into PDF document

Dim pdfDocument As PdfDocument = converter.ConvertToPDF(wordDocument)

'Save the PDF file to file system

pdfDocument.Save("WordtoPDF.pdf")

'close the instance of document objects

Converting TIFF to PDF

Converting multi page TIFF to PDF

Multi frame TIFF image can be converted to PDF document. 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.

//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

	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, PointF.Empty, size);

}

//Save and close the document

pdfDocument.Save("Sample.pdf");

pdfDocument.Close(true);

Save(memoryStream, "Sample.pdf");
//Initialize XPS to PDF converter.

XPSToPdfConverter converter = new XPSToPdfConverter();

//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); 

//If the position is not set to '0' then the PDF will be empty.

stream.Position = 0;

//Close the documents.
