    public PdfTrueTypeFont(Stream fontStream, float size)
    Parameters
    Type Name Description
    System.IO.Stream fontStream
    System.Single size

    The size.

    PdfTrueTypeFont(Stream, Single, PdfFontStyle)

    Parameters
    Type Name Description
    System.IO.Stream fontStream
    System.Single size

    The size.

    PdfFontStyle style

    The style.

    PdfTrueTypeFont(Stream, Single, Boolean, Boolean)

    Initializes a new instance of the PdfTrueTypeFont class with the specified font stream, font size, and embedding options.

    Declaration
    public PdfTrueTypeFont(Stream fontStream, float size, bool embed, bool subset)
    Parameters
    Type Name Description
    System.IO.Stream fontStream

    A Stream object that represents the font stream data.

    System.Single size
    System.Boolean embed

    A boolean value that specifies whether to embed the font with the PDF document.

    System.Boolean subset

    A boolean value that specifies whether to subset the font to only include the characters used in the document.

    Remarks

    If the embed parameter is true, the font stream data will be embedded in the PDF document. This ensures that the font will be available for viewing and printing, even if the original font is not installed on the user's computer. If the subset parameter is true, only the characters used in the document will be included in the embedded font.This can reduce the size of the PDF document, but may also make it more difficult to edit the document in the future.

    //Create a new PDF document.
    PdfDocument document = new PdfDocument();
    //Add a page to the document.
