A TrueType Collection (TTC) is a collection of TrueType fonts combined into a single file structure. In TrueType Collections the common glyphs are shared among the fonts present in the collection and reduces file space. DynamicPDF accesses TTC fonts using an index or font name. For example, if a TTC contains four TrueType fonts, then each font's index is determined by its location in the TTC, beginning with zero index value.

The following examples illustrate using a TTC by specifying index and a TTC by specifying font name.

TTC Specifying Index

[Java]
//Create a TextArea
TextArea area = new TextArea("Hello TTC Testing", 100, 100, 100, 100);

//Create a open type font collection.
OpenTypeFontCollection collection = new OpenTypeFontCollection("[fontCollectionPath]/font.ttc");
                
//Assign opentype font to label from Collection using the Index
area.setFont(collection.getFont(1));

TTC Specifying Font Name

[Java]
//Create a open type font collection.
OpenTypeFontCollection collection = new OpenTypeFontCollection("[fontCollectionPath]/font.ttc");

//Gets all font names present in the TTC
String[] fontNames = collection.getFontNames();

//Getting Font from collection using font name.
OpenTypeFont font = collection.getFont(fontNames[0]);
