DR 09-0042, WML, Fonts: notTrueType attribute missing from list

[Chris Rae]

I think this is the right place for notTrueType. I'm looping in Suzuki-san in case he has any thoughts, though.

Subject: DR 09-0042, WML, Fonts: notTrueType attribute missing from list


The resolution adopted was simply to add the notTrueType element to the list of elements; however, given the concern about ordering of entries in this list (see resolution to DR 09-0041), where should this new element be inserted? For now, I have placed it at the end, and the current combination of DRs 09-0041 and 0042 is, as follows:

Part 1, §17.8.2, "Font Substitution", p. 751

The exact algorithm which is used for font substitution is highly dependent on the characteristics which are most desirable when performing the substitution: similar appearance of each glyph (to maximize visual familiarity), similar physical characteristics (to minimize changes in line height and breaking), etc. ISO/IEC 29500 recommends that applications looking for the closest match to the following pieces of information (in descending priority) in order to determine a suitable alternative font; however, applications are free to apply more sophisticated logic in its place:

     *   sig (§17.8.3.16)

     *   charset (§17.8.3.2)

     *   panose1 (§17.8.3.13)

     *   sig (§17.8.3.16)

     *   charset (§17.8.3.2)

     *   pitch (§17.8.3.14)

     *   family (§17.8.3.9)

     *   altName (§17.8.3.1)

     *   notTrueType (§17.8.3.12)
