Constructor Details

PDCIDFontType2Embedder

PDCIDFontType2Embedder(PDDocument document,
 COSDictionary dict,
 TrueTypeFont ttf,
 boolean embedSubset,
 PDType0Font parent,
 boolean vertical)
                throws IOException

Creates a new TrueType font embedder for the given TTF as a PDCIDFontType2.

Parameters:

document - parent document

dict - font dictionary

ttf - True Type Font

parent - parent Type 0 font

Throws:

IOException - if the TTF could not be read

Method Details
