Adds a font reference to the document.





int AddFont(string name) int AddFont(string name, LanguageType language) int AddFont(string name, LanguageType language, bool vertical)



Name Description
name The name of the font typeface.

The language type to use. The LanguageType enumeration may take the following values:

  • Latin
  • Unicode - NB: This requires that the font be embedded. If you wish to use this selector use the EmbedFont call.
  • Korean
  • Japanese
  • ChineseS
  • ChineseT

See the Fonts and Languages section for details on language types. The default language type is Latin.


Whether the text direction should be vertical.

See the Fonts and Languages section for details on writing directions. The default is false to indicate standard left to right layout.

return The Object ID of the newly added Font Object.




Adds a font to the document.

The font name and a description of the font style is held within the document. However the actual font itself is not added to the document unless the language is Unicode. (When Unicode is specified, this method will embed the font without subsetting.) If you wish to embed a font or use the Unicode language, you should use the EmbedFont method.

When a client opens the PDF Acrobat will attempt to find the exact same font on the client system. If the exact font is not available then a substitute font will be chosen using the font description to determine the best match.

The following fonts are guaranteed to be available on every system.

  • Times-Roman
  • Times-Bold
  • Times-Italic
  • Times-BoldItalic
  • Helvetica
  • Helvetica-Bold
  • Helvetica-Oblique
  • Helvetica-BoldOblique
  • Courier
  • Courier-Bold
  • Courier-Oblique
  • Courier-BoldOblique
  • Symbol
  • ZapfDingbats

Additionally you can add any TrueType, OpenType or Type 1 font that you have installed on your system. The name you should use is the one referenced in your fonts folder. For example.

  • Arial
  • Arial Black
  • Arial Black Italic
  • ...
  • Book Antiqua
  • Book Antiqua Bold
  • Book Antiqua Bold Italic
  • Book Antiqua Italic
  • ...
  • Venetian301BT
  • Venetian301BT Bold
  • ...

The AddFont function returns the Object ID of the newly added Font Object. Typically you will want to assign this return value to the document Font property using code of the form.


theDoc.Font = theDoc.AddFont("Courier");

If the specified font could not be found then you will get an Object ID of zero returned. You may wish to check for this possibility otherwise a default font will be used.

Fonts are cached so newly added fonts will not be available to ABCpdf until the application is restarted. If you need to dynamically load a font you can pass this method a path to your font file. This will add the font to the cache and make it available for use. You should not move, rename or delete a font file which has been dynamically loaded using this technique.

Why is my language a string?

In older versions of ABCpdf the language parameter was a string. So you might find code of this form.


theDoc.AddFont("Courier", "Latin");

In more recent releases the language parameter has been changed to a true enumeration. This is a safer way of coding as it allows the compiler to ensure that the values you are using are valid. Your new code should look like this.


theDoc.AddFont("Courier", LanguageType.Latin);

The names of the items in the LanguageType enumeration are the same as the values of the strings used in previous versions. So changing your code should be a simple search and replace operation. If you see a language of "" this equates to LanguageType.Latin.





The following code adds two pieces of text to a document. The first piece is in Times-Roman and the second in Helvetica-Bold.


using (Doc doc = new Doc()) {   doc.FontSize = 48;   string theFont = "Times-Roman ";   doc.Font = doc.AddFont(theFont);   doc.AddText(theFont);   theFont = "Helvetica-Bold";   doc.Font = doc.AddFont(theFont);   doc.AddText(theFont);   doc.Save(Server.MapPath("docaddfont.pdf")); }
