CPAL v. 1 is the result of collaboration between Adobe and Microsoft, and some of the latest points raised in that discussion haven't been reflected in your redline draft.

Attached please find proposed changes to CPAL v. 1 (a Word doc with Track Change "on"; the original text is from your redline draft).

With this revision, we've separated the orthogonal concepts of palette type and palette label.

Please remove the two new name table IDs for light and dark background palettes in your redline draft - they are not needed with this proposal.

Dear AHG members,

As you know, at the last MPEG meeting we received three responses for the previously published CFP for color fonts and math layout technology. As the results, the resolution accepted at the meeting was to harmonize all three proposals and integrate them in the current working draft of 3rd edition of the ISO/IEC 14496-22 "Open Font Format". The revised, red-line version of the working draft is attached to this email for your review and comments.

One of the mandates the AHG has until the next MPEG meeting is to study the text of the working draft and prepare the recommendations (and input contributions, if necessary) to be reviewed at the next meeting in early April. The original plan was to finalize the working draft and promote it to the next Committee Draft stage - I believe this can be accomplished if we make sure that all comments and changes are discussed and submitted by this AHG for consideration at the next meeting. One possible change could be e.g. the integration of the proposed new color bitmap tables with the existing embedded bitmap tables; however, this requires further feasibility studies to make sure that this change (if it were to be adopted) would not  affect any existing implementations.

We also have the mandates to review and study the draft amendment of the ISO/IEC 14496-18 "Font compression and streaming" and the draft corrigendum of ISO/IEC 14496-28 "Composite Font Representation" - both documents have been discussed on the list a while ago, and both are now under ballots.

Looking forward to your comments on the attached red-line text of the WD. A special request to all who submitted the proposals in response to the CFP - please review the changes for accuracy and report to this list anything that you may have found that needs to be revised.

Thank you very much,
