I think that you are looking at the vector font encodings and trying to
apply them to TrueType fonts.

So, you can go one way or the other:

TrueType:
text = Obj_New('IDLgrText', ENABLE_FORMATTING=1, $
"(!10W!X) Greek Symbol Omega", color=[0,0,128])
XObjView, text

Hershey vector fonts:

oFont = OBJ_NEW('IDLgrFont', 'Hershey')
xobjview, obj_new('idlgrtext', '(!4!Z(58)!X) Greek Symbol Omega',
FONT=oFont, /ENABLE_FORMATTING)
