   Okay, there is a PaintType attribute that describes an outline
action.  It says that a font that is designed to be "filled" can
be "outlined" instead.  PaintType can be part of a font definition.

   In the "Blue Book", "PostScript Language Tutorial and Cookbook",
Adobe Systems Incorporated, there is a routine that creates an outline
font from a filled font (page 203).  So the above makes sense If both
fonts are in both documents.  Not that there are not fonts that are not
filled.  To be filled, an outline must exist defining a glyph.  The Blue
Book and the Language Reference can be downloaded as PDF's. 

   Some fonts are based on lines that are stroked.  Think 'Courier' where
all the lines that make up a glyph have the same width.  And some
fonts are made up of bitmaps.  They cannot be filled or outlined either.
And there are a bunck of fonts that are repackaged True Type fonts.
The outline information may not be available?  And there are/were
encrypted fonts that can't be modified.

   So, examine your font and find out if it is the right type to have an
outline that can be accessed to create a new font.  (The fact that you
are having problems implies...)

   Can you use a standard font to create your document?  That may be
a way to get an acceptable result.

Steve N.
