Flags for PDE font creation routine. If you want to subset a font, set both the IG_PDE_FONT_CREATE_EMBEDDED and IG_PDE_FONT_WILL_SUBSET flags.

Values:

IG_PDE_FONT_CREATE_NOT_ALLOWED	-1	Creation is not allowed. Usually returns by SysFont's "getCreateFlags" when the combination of SysFont and SysEncoding is not allowed.
IG_PDE_FONT_CREATE_EMBEDDED	0x0001	Embed the font. Create an embedded font. By itself, this will not subset the font.
IG_PDE_FONT_WILL_SUBSET	0x0002	Subset the font. If you want to subset a font, set both the IG_PDE_FONT_CREATE_EMBEDDED and IG_PDE_FONT_WILL_SUBSET flags. You must call "subsetNow" to actually subset the font. Both embedding and sub-setting a font creates a CFF font.
IG_PDE_FONT_DO_NOT_EMBED	0x0004	Do not embed the font. You cannot set both this and the IG_PDE_FONT_WILL_SUBSET flags. Nor can you set IG_PDE_FONT_CREATE_EMBEDDED.
IG_PDE_FONT_ENCODE_BY_GID	0x0008	Create a CIDFont with identity (GID) encoding.
IG_PDE_FONT_DEFER_WIDTHS	0x0010	Wait to get widths until later (affects Type0 fonts only).
IG_PDE_FONT_CREATE_SUBSET	0x0002	Subset the font. If you want to subset a font, set both the IG_PDE_FONT_CREATE_EMBEDDED and IG_PDE_FONT_WILL_SUBSET flags. You must call "subsetNow" to actually subset the font. Both embedding and sub-setting a font creates a CFF font.
IG_PDE_FONT_CREATE_GID_OVERRIDE	0x0020	The library will convert cp to gid with identity embedded.
IG_PDE_FONT_CREATE_TO_UNICODE	0x0040	Create ToUnicode cmap.
IG_PDE_FONT_CREATE_ALL_WIDTHS	0x0080	Supply entire widths table (affects Type0 fonts only).
