Hi,

Using Aspose Words for .NET,

How do you set the default font and font sizes when converting from HTML to PDF?

Version: Aspose Words Version 19.3.0

Note: I’ve already asked this in separate post, but was given a Aspose PDF solution, I need the code for setting it in using Aspose Words.

Thank you.

@jdacz When you open HTML document using Aspose.Words, the document is loaded into Aspose.Words DOM and if you need to change font used by the document, you should change font of the nodes in the document. For example, you can use DocumentVisitor to achieve this. For example see the following code:

Document doc = new Document(@"C:\Temp\in.html");
FontChanger changer = new FontChanger("Arial");
doc.Accept(changer);
doc.Save(@"C:\Temp\out.pdf");

class FontChanger : DocumentVisitor
{
    public FontChanger(string fontName)
    {
        mFontName = fontName;
    }

    /// <summary>
    /// Called when a FieldEnd node is encountered in the document.
    /// </summary>
    public override VisitorAction VisitFieldEnd(FieldEnd fieldEnd)
    {
        //Simply change font name
        ResetFont(fieldEnd.Font);
        return VisitorAction.Continue;
    }

    /// <summary>
    /// Called when a FieldSeparator node is encountered in the document.
    /// </summary>
    public override VisitorAction VisitFieldSeparator(FieldSeparator fieldSeparator)
    {
        ResetFont(fieldSeparator.Font);
        return VisitorAction.Continue;
    }

    /// <summary>
    /// Called when a FieldStart node is encountered in the document.
    /// </summary>
    public override VisitorAction VisitFieldStart(FieldStart fieldStart)
    {
        ResetFont(fieldStart.Font);
        return VisitorAction.Continue;
    }

    /// <summary>
    /// Called when a Footnote end is encountered in the document.
    /// </summary>
    public override VisitorAction VisitFootnoteEnd(Footnote footnote)
    {
        ResetFont(footnote.Font);
        return VisitorAction.Continue;
    }

    /// <summary>
    /// Called when a FormField node is encountered in the document.
    /// </summary>
    public override VisitorAction VisitFormField(FormField formField)
    {
        ResetFont(formField.Font);
        return VisitorAction.Continue;
    }

    /// <summary>
    /// Called when a Paragraph end is encountered in the document.
    /// </summary>
    public override VisitorAction VisitParagraphEnd(Paragraph paragraph)
    {
        ResetFont(paragraph.ParagraphBreakFont);
        return VisitorAction.Continue;
    }

    /// <summary>
    /// Called when a Run node is encountered in the document.
    /// </summary>
    public override VisitorAction VisitRun(Run run)
    {
        ResetFont(run.Font);
        return VisitorAction.Continue;
    }

    /// <summary>
    /// Called when a SpecialChar is encountered in the document.
    /// </summary>
    public override VisitorAction VisitSpecialChar(SpecialChar specialChar)
    {
        ResetFont(specialChar.Font);
        return VisitorAction.Continue;
    }

    private void ResetFont(Aspose.Words.Font font)
    {
        font.Name = mFontName;
    }

    private string mFontName = "Arial";
}
