Public NotInheritable Class PdfSystemFonts

Properties

	Name	Description

Methods

	Name	Description
	IsFamilyInstalled	Returns true if a font family with the specified name is installed on the host system. Case-insensitive.
	LoadFontBytes	Resolves a system font to its raw font-file bytes (TrueType / OpenType). Throws PdfDocumentException if the family isn't installed or its bytes can't be read.

Remarks

Use InstalledFamilies to enumerate every installed family name, and IsFamilyInstalled(String) to test for a specific family. Pass a resolved family name to Add(PdfSystemFont) or CreateFromSystemFont(String, Single) to load and embed it into a document.

The installed-family list is read from the host OS the first time it is accessed and cached for the lifetime of the process. Fonts installed after that point won't appear.

Example

Copy

foreach (string family in PdfSystemFonts.InstalledFamilies)
    System.Console.WriteLine(family);

if (PdfSystemFonts.IsFamilyInstalled("Arial"))
{
    byte[] bytes = PdfSystemFonts.LoadFontBytes("Arial", PdfFontStyle.Bold);
}

For Each family As String In PdfSystemFonts.InstalledFamilies
    System.Console.WriteLine(family)
Next

If PdfSystemFonts.IsFamilyInstalled("Arial") Then
    Dim bytes As Byte() = PdfSystemFonts.LoadFontBytes("Arial", PdfFontStyle.Bold)
End If
