I would like to create a composite font in which a few of the characters in the Time-Roman font are replaced with characters from the Symbol font. I have studied the examples of font encoding in the blue book and those in Real World Postscript but have so far failed to get anything to work. As a relative postscript novice I would appreciate any assistance you could give me (and especially a concrete example I could follow). Many thanks Ian

I am trying to create a composite font that contains characters I define
plus outlines from a built in font. I have no trouble creating the composite
font. But when I try to insert an character path from a built in font, no
visible marks are made on the page for that character
From the red PostScript book, the font chapter (5) defines the entries in
a built-in font . One of the elements is CharStrings. My understanding is that
the following code should place the character's shape desription on the stack where
I should be able to stroke it :
FontDirectory begin /Courier findfont 10000 scalefont begin CharStrings /b get end end 100 100 moveto stroke
I expect to get a 10 point lower case b at position 100,100 .
Any ideas ?
Thanks

This is inherently Very Difficult (I won't say "impossible" because Woody probably has a back-door way to it:-) since the outlines in a built-in font are stored in a protected, encoded form. However, we can make some progress on the code presented... > FontDirectory begin /Courier findfont ... The "FontDirectory begin" is unnecessary; "findfont" searches FontDirectory (by default). >... 10000 scalefont ... This scales to 10000 points (relative to user space), not 10. Scalefont works in terms of page coordinates--the internal 1000-units-to-the-em factor is compensated out. >... begin CharStrings /b get end end 100 100 moveto stroke > > I expect to get a 10 point lower case b at position 100,100 . After the "/b get" you've picked up the value of the CharStrings entry for the character b, but you haven't done anything with it. You've got something on the stack representing a procedure for producing the outline for the character; however, at this point the problems are: - it's only on the stack; it's not in the path yet, so there's nothing to stroke - it's not clear how to get it into the path, since the object is in some unspecified (the red book says "proprietary") format -- Dick Dunn rcd@ico.isc.com -or- ico!rcd Boulder, CO (303)449-2870 ...Never offend with style when you can offend with substance.
