5 Sep 202424 minutes to read

The Essential DocIO provides settings while performing Word to PDF conversion mentioned below,

Fast rendering

This setting allows you to convert PDF faster by using direct PDF rendering approach rather than EMF rendering approach.

The following code sample shows how to convert the Word document to PDF using direct PDF rendering approach.

NOTE

Refer to the appropriate tabs in the code snippets section: C# [Cross-platform] for ASP.NET Core, Blazor, Xamarin, UWP, .NET MAUI, and WinUI; C# [Windows-specific] for WinForms and WPF; VB.NET [Windows-specific] for VB.NET applications.

//DocIO supports Word to PDF fast rendering in Windows forms, WPF, ASP.NET and ASP.NET MVC platform alone
//Loads an existing Word document
WordDocument wordDocument = new WordDocument("Template.docx", FormatType.Docx);
//Initializes the ChartToImageConverter for converting charts during Word to pdf conversion
wordDocument.ChartToImageConverter = new ChartToImageConverter();
//Sets the scaling mode for charts (Normal mode reduces the Pdf file size)
wordDocument.ChartToImageConverter.ScalingMode = ScalingMode.Normal;
//Creates an instance of the DocToPDFConverter - responsible for Word to PDF conversion
DocToPDFConverter converter = new DocToPDFConverter();
//Sets true to enable the fast rendering using direct PDF conversion.
converter.Settings.EnableFastRendering = true;
//Converts Word document into PDF document
PdfDocument pdfDocument = converter.ConvertToPDF(wordDocument);
//Saves the PDF file to file system
pdfDocument.Save("WordtoPDF.pdf");
//Closes the instance of document objects
pdfDocument.Close(true);
wordDocument.Close();
'Loads an existing Word document
Dim wordDocument As New WordDocument("Template.docx", FormatType.Docx)
'Initializes the ChartToImageConverter for converting charts during Word to pdf conversion
wordDocument.ChartToImageConverter = New ChartToImageConverter()
'Sets the scaling mode for charts (Normal mode reduces the Pdf file size)
wordDocument.ChartToImageConverter.ScalingMode = ScalingMode.Normal
'creates an instance of the DocToPDFConverter - responsible for Word to PDF conversion
Dim converter As New DocToPDFConverter()
'Sets true to enable the fast rendering using direct PDF conversion.
converter.Settings.EnableFastRendering = true
'Converts Word document into PDF document
Dim pdfDocument As PdfDocument = converter.ConvertToPDF(wordDocument)
'Saves the PDF file to file system
pdfDocument.Save("WordtoPDF.pdf")
'Closes the instance of document objects
pdfDocument.Close(True)
wordDocument.Close()

Hyphenation in Word-to-PDF conversion

Essential DocIO now allows hyphenating text in a Word document while converting it to PDF format based on the given language dictionaries. These dictionaries prescribe where words of a specific language can be hyphenated. Use the dictionary files as OpenOffice format dictionary.

NOTE

If automatic hyphenation is not enabled in the Word document, you can enable it by using WordDocument.Properties.Hyphenation.AutoHyphenation of DocIO.

The following code sample shows how to hyphenate text in a Word document while converting it to PDF format.

FileStream fileStream = new FileStream("Template.docx", FileMode.Open);
//Loads an existing Word document

//Instantiates DocIORenderer instance for Word to PDF conversion
DocIORenderer renderer = new DocIORenderer();
//Reads the language dictionary for hyphenation
FileStream dictionaryStream = new FileStream("hyphen_en_US.dic", FileMode.Open);
//Adds the hyphenation dictionary of the specified language
Hyphenator.Dictionaries.Add("en-US", dictionaryStream);
//Converts Word document into PDF document
PdfDocument pdfDocument = renderer.ConvertToPDF(wordDocument);
//Closes the instance of Word document object
wordDocument.Close();
//Releases the resources occupied by DocIORenderer instance
