IOException

Create a subset name-keyed cff based on the given parameters

Parameters:

subset - The set of glyphs to include in the subset

out - The OutputStream to which we will write the new font

fsType - The fsType to include in the new font

rebuildCharstrings - Tells if the charstrings in the current font already take into account the Subset. If they do, then we don't need to recreate the charstrings. Otherwise, we do.

fetcher - Provides a way to get from gid to glyphName for cases where there is no charset (for example, because this NameKeyedFont is a temporary font converted from Type1). Can be null if this's charset and string index are valid.

Throws:

InvalidFontException
