    • setFont

      public T setFont (PdfFont font)
      Sets the font of this Element.

      This property overrides the value set by setFontFamily(java.lang.String...). Font is set either via exact PdfFont instance or via font-family name that should correspond to the font in FontProvider, but not both.

      Parameters:
      font - a font
      Returns:
      this Element.

    • setFontFamily

      public T setFontFamily (String... fontFamilyNames)
      Sets the preferable font families for this Element. Note that FontProvider shall be set as well. See RootElement.setFontProvider(FontProvider)

      All String that are passed as argument are directly handled as a collection of font family names, without any pre-processing. Every font family name is treated as a preferable font-family to be used inside the element. The fontFamilyNames argument is interpreted as as an ordered list, where every next font-family should be used if font for the previous one was not found or doesn't contain required glyphs.

      Parameters:
      fontFamilyNames - defines an ordered list of preferable font families for this Element.
      Returns:
      this Element.
