Constructor Detail

PDCIDFont

public PDCIDFont(COSDictionary dictionary,
                 CMap cMap)

Constructor from COSDictionary and CMap with code -> cid mapping.

Parameters:

dictionary - is COSDictionary of CIDFont.

cMap - is CMap object containing mapping code -> cid.

PDCIDFont

public PDCIDFont(COSDictionary dictionary,
                 CMap cMap,
                 FontProgram fontProgram,
                 boolean isFontParsed)

Constructor that sets font program for this CIDFont. Can be used when font program should not be parsed twice and is already read.

Parameters:

dictionary - is COSDictionary of CIDFont.

cMap - is CMap object containing mapping code -> cid.

fontProgram - is embedded font program associated with this CIDFont.

isFontParsed - is true if embedded font program has been already parsed.
