The dictionary maps glyph names to content streams. Each stream defines how to paint one glyph. The stream must begin with either a d0 or d1 operator that reports the glyph width and, for d1, the bounding box.

The glyph stream can use any PDF drawing operators to paint the glyph shape, including paths, images, and shading. The Resources entry in the font dictionary lists any external resources these streams need.
