We recently hit again the problem to render an image on a particular system
while the image refers to fonts available only in the producing environment of
this image.

In order not to port all font descriptions available on image producing systems
to the rendering systems we started to think about font substitution.

Looking at ISO 9541-1 "Information processing - Text and office systems - Font
information interchange" there is the concept of font reference containing both
a worldwide unique name for the font in question and a set of properties for
the font and its glyphs that allow (??) searching for a matching font if the
requested one is not available.

Currently we have implemented a hack that simply accumulates weights for
matching components and takes that font with the highest resulting value. But,
we think for real font substitution this is not satisfactory.

Now our questions:

	- Are there any atricles, books etc. about font substitution?
	- Are pieces of software about this topic in the public domain?
	- Any other help?

Thanks in advance,

Thomas Oeser
