It says in the PhotoFont specification that it's possible for a glyph to have more than one image. In the kerning section of the specification it allows you then to refer to a specific image in a glyph. Aside from that I don't see any other reference to the notion of having multiple images per glyph.
My question is what does it mean when a glyph has multiple images and I need to retrieve the metrics or the image for that glyph? How do I know which image associated with the glyph to pick? Are there any PhotoFonts out there that actually use this part of the spec?
Thanks for your help,
