Class FontProvider

java.lang.Object

com.itextpdf.layout.font.FontProvider

Direct Known Subclasses:

BasicFontProvider

public class FontProvider
extends Object

Main entry point of font selector logic. Contains reusable FontSet and collection of PdfFonts. FontProvider depends on PdfDocument due to PdfFont, so it cannot be reused for different documents unless reset with reset() or recreated with getFontSet(). In the former case the FontSelectorCache is reused and in the latter it's reinitialised. FontProvider the only end point for creating PdfFont.

It is allowed to use only one FontProvider per document. If temporary fonts per element needed, additional FontSet can be used. For more details see Property.FONT_SET, getPdfFont(FontInfo, FontSet), getStrategy(String, List, FontCharacteristics, FontSet).

Note, FontProvider does not close created FontPrograms, because of possible conflicts with FontCache.
