<p class="MsoNormal">Dear AHG members,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It’s been a while since the CFR standard (ISO/IEC 14496-28:2012) has been published, and, as more and more implementers start working with the spec, I received some questions regarding certain parts and definitions that would benefit from
additional clarifications and updates. In an attempt to clarify some of the implementer’s questions I had off-list discussions with the developers, and the results of the discussions can be roughly subdivided into the following categories:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>How to deal with missing or inconsistent font metrics data (where components font metrics may differ from one another and from the metrics defined by CFR resource;<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>How individual component fonts can be adjusted to fit the composite font structure, and how the adjustment affects overall font metrics;<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Clarify the priority order of the component definitions and if/how user language preferences may affect the component font priority order;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As the editor of the spec, I took the liberty to collect the answers to those questions and compile them into the spec amendment language – the draft proposal is attached here for your review. There are still some questions remaining (about
‘macStyle’ and ‘italic’ arguments of ‘FontMetrics’ element) that need to be finalized – I propose that after reviewing the draft the AHG should make a recommendation to start the amendment to update the language of the standard.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you,<o:p></o:p></p>
