Usage Examples:

IMAGINGJAVA-2050 Improve default font option usage on Linux

Please create folder - "fonts" in project, and add in this folder required fonts.
And execute this code:


FontSettings.setFontsFolder("fonts");
FontSettings.setGetSystemAlternativeFont(false);
exportToPng("missing-font2.odg", "Arial", "arial.png");
exportToPng("missing-font2.odg", "Courier New", "courier.png");



private static void exportToPng(String filePath, String defaultFontName, String outfileName)
{
  FontSettings.setDefaultFontName(defaultFontName);
  try (Image document = Image.load(filePath))
  {
     PngOptions saveOptions = new PngOptions();
	 odgOptions = new OdgRasterizationOptions()
     saveOptions.setVectorRasterizationOptions(odgOptions);

  }
}
