Actually the WebCGM Profile does address font substitution for interpreters. See T.26.6. I agree that implementing a standard font mapping file requires a change to that table with a reference to the new Chapter 9.
It also addresses it on the generator side in T.25.4.

Dave, not sure if you have email access by now. I wouldn't mind getting your thoughts on this?

I was under the impression the spec allowed a font mapping mechanism, but it doesn't. The only thing the spec says is that if the font is not present, the default font should be used.
This, to me, is a user agent feature. If it gets standardize, the profile would need to change.
I would be in favor (if doable) to change the profile and help the situation by, for example: - allowing a list of font index (instead of one) on text elements, (if the first font is not available, try the following one, and so on). - allowing generic font-families: serif, sans-serif, cursive, fantasy, monospace - modifying the list of allowed fonts in the profile, i.e., select fonts that are available on multiple platforms.
Overall, I would try to get rid of the font mapping mechanism instead of standardizing it. Also I wonder if something that has been around for 17 years should be modified. If users are accustomed to the vendors files, why change them and possibly risk new font related issues.

Every CGM product (viewer and illustrating packages) I've worked with over the last 17 years has a font mapping mechanism. This was an attempt to standardize that file. Whether my computer (platform independent)has helvetica, arial, swiss, etc., it allows me to control the display font that I want to use from what is called out in the CGM file. The WebCGM Profile calls out the Adobe 13 fonts. Included in that list is 'Helvetica' (case insensitive). Helvetica is not a font that Microsoft distributes in windows. It does distribute Arial. I do have Helvetica in my unix box, but I also have Swiss on that box. I may want to use it instead.
Font mapping has been around for a long time in the CGM community.

I've been thinking about this for a while, and I'm not convinced this will help interoperability. I'm referring mostly to the font mapping section.
Are there any restrictions on the content of <cgmFont>? Are there any restrictions on the content of <displayFont>?
Are the problems mainly when going from Unix to Windows (and vice versa)? What's a typical (frequent) scenario?

I found a problem in the WebCGM configuration DTD, fixed it, and created sample instance to demonstrate its usage.
The instance is made up using some of the PTC font mapping table and some Boeing settings for the style properties.
I have not incorporated scaling of the font glyphs in the x and y direction yet, but will do that at the mapping level.
The font mapping was set up only to be used by viewers. I could extend it to cover both import and export, so it could be applied to illustrating packages (thoughts?)
Thx...Dave <<webcgmConfig.dtd>> <<myconfig.xml>>
