public TTFFont(String baseFont,
 PDFObject fontObj,
 PDFFontDescriptor descriptor)
        throws IOException

Throws:

IOException

TTFFont

public TTFFont(String baseFont,
 PDFObject fontObj,
 PDFFontDescriptor descriptor,
 File fontFile)
        throws IOException

create a new TrueTypeFont object based on a description of the font from the PDF file. If the description happens to contain an in-line true-type font file (under key "FontFile2"), use the true type font. Otherwise, parse the description for key information and use that to generate an appropriate font.

Throws:

IOException
