Methods

	Name	Description
	Add(Byte)	Adds a TrueType / OpenType font loaded from an in-memory byte array. Convenience overload that avoids needing a temporary file.
	Add(PdfFont)	Adds an already-constructed PdfFont to the collection. Useful when you want to track a font that was created with an explicit size via CreateStandardFont(PdfStandardFont, Single) etc.
	Add(PdfFont)	Adds an array of fonts to the collection.
	Add(PdfStandardCJKFont)	Adds a standard CJK font to the collection. Like PdfStandardFont, these are referenced by name (not embedded) — but CJK readers ship the glyphs, so output is expected to render on PDF/A-capable viewers.
	Add(PdfStandardFont)	Adds a standard PDF font (one of the 14 built-in font names) to the collection and returns the PdfFont wrapper. Standard fonts are referenced by name, not embedded — rejected under PDF/A and PDF/X conformance.
	Add(PdfSystemFont)	Resolves the system font described by systemFont to its installed TrueType / OpenType file, subset-embeds it into the document, and returns the resulting PdfFont.
	Add(Stream)	Adds a TrueType / OpenType font loaded from a Stream. The stream is read synchronously from its current position to end.
	Add(String)	Adds a TrueType / OpenType font loaded from a file. The font is subset-embedded into the output document — use this path for PDF/A / PDF/X output from scratch.
	Add(PdfSystemFont, Boolean)	Resolves the system font described by systemFont and adds it to the collection.
	Contains	Returns true if the specified font is in the collection.
	GetEnumerator	Returns an enumerator over the fonts in insertion order.
	IndexOf	Returns the zero-based index of the specified font, or -1 if not found.
	Insert	Inserts a font at the specified zero-based index.
	Remove	Removes the specified font from the collection.

Remarks

Adding a font returns a PdfFont that can be retained and reused with any PdfTextElement on the document. Adding the exact same font twice returns two distinct registry entries — duplicate detection is left to the caller.

Example

Copy

PdfDocument document = new PdfDocument();
PdfFont helvetica = document.Fonts.Add(PdfStandardFont.Helvetica);
PdfFont arial = document.Fonts.Add(@"C:\Windows\Fonts\arial.ttf");
int count = document.Fonts.Count;

Dim document As New PdfDocument()
Dim helvetica As PdfFont = document.Fonts.Add(PdfStandardFont.Helvetica)
Dim arial As PdfFont = document.Fonts.Add("C:\Windows\Fonts\arial.ttf")
Dim count As Integer = document.Fonts.Count
