  • WOFF 1.0 -> OpenType and WOFF 2.0

  • EOT (uncompressed v2 only) -> OpenType

  • Supports extracting PostScript Type0/Compsoite, Bare CFF and TTF fonts.
  • PdfFontExtractor will normalize TTF fonts to make sure they are valid in all major web browsers.
Can only convert these types with PdfFontExtractor utility
  • PostScript Type0/Composite -> OpenType/TTF and WOFF 1 & 2

Usage

Converting a font (in this case to OTF)
FVFont font = FontVerter.convertFont(inputFontFile, FontVerter.FontFormat.OTF);
FileUtils.writeByteArrayToFile(new File("MyFont.otf"), font.getData());
Reading a font file
File file = new File("FontVerter+SimpleTestFont.otf");
FVFont font = FontVerter.readFont(file);
Attempt to normalize and fix an invalid font
File file = new File("FontVerter+SimpleTestFont.otf");
FVFont font = FontVerter.readFont(file);

if (!font.isValid())
    font.normalize();

FileUtils.writeByteArrayToFile(new File("fixed-font.otf"), font.getData());
PDF Font Extractor command line
PdfFontExtractor <PDF file or directory containing PDF files>

Options:
-ff=<format> Font format to save the fonts as. <format> = WOFF1, WOFF2, OTF. Defaults to OTF.
-dir=<path> Directory to extract to. <path> = font extract directory. Defaults to {current dir}/fonts/
PDF font extractor programatically
File pdf = new File("test.pdf");
PdfFontExtractor extractor = new PdfFontExtractor();

// extract directly to a directory
extractor.extractFontsToDir(pdf, TestUtils.tempOutputPath);

// or extract to list of FVFonts for further manipulation
List<FVFont> fonts = extractor.extractToFVFonts(doc);
You can’t perform that action at this time.
