Class FontProvider

java.lang.Object

com.itextpdf.layout.font.FontProvider

public class FontProvider
extends Object

Main entry point of font selector logic. Contains reusable FontSet and collection of PdfFonts. FontProvider depends from PdfDocument, due to PdfFont, it cannot be reused for different documents, but a new instance of FontProvider could be created with getFontSet(). FontProvider the only end point for creating PdfFont.

It is recommended 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.
