The Multiple Master Menu
========================

The MM Menu provides a few commands for manipulating
:ref:`Multiple Master or Apple distortable fonts <multiplemaster.MM>`. If the
current font is a MM itself font the menu also includes a list of all font
instances that make up this one. This menu is available in the
:ref:`font view <mmmenu.fontview>` and the
:ref:`outline glyph view <mmmenu.outline-char>`.


.. _mmmenu.fontview:

The menu as it appears in the font view

.. _mmmenu.Create:

.. object:: Create MM

   Brings up the :doc:`multiple master dialog </ui/dialogs/multiplemaster>` and allows you
   to create your own multiple master font from scratch.

.. _mmmenu.Valid:

.. object:: MM Valid

   Checks that the current multiple master font can be saved. So each master
   design must match in:

   * Contours

     * There must be the same number of contours and
     * each contour must have the same number of points and
     * each spline on the contour must be the same type (ie it can't correspond to a
       straight line in one font and a curve in another)
   * References

     * There must be the same number of references and
     * Each corresponding reference must refer to the same encoding
   * Hints

     * Same number of hints
   * HintMasks (Counter masks are not supported here)

     * HintMasks at corresponding points must specify a corresponding set of hints
   * Kerning

     * If a glyph kerns with another glyph in one font, then a corresponding kerning
       pair must exist in all designs

.. _mmmenu.Info:

.. object:: MM Info

   Brings up the :doc:`multiple master dialog </ui/dialogs/multiplemaster>` and allows you
   to modify the current multiple master font.

.. _mmmenu.NewFont:

.. object:: Blend to New Font...

   Allows you to create a blended version of the current multiple master font
   set as a stand alone font.

.. _mmmenu.DefWeights:

.. object:: MM Change Default Weights

   Allows you to change the default weights assigned to each master design used
   in blending the default instance of the font

--------------------------------------------------------------------------------

.. object:: <sub font name>

   Clicking on a different sub font name in the menu will cause that sub-font to
   be displayed instead of the current one. The subfonts are the master designs
   and the default blended font.


.. _mmmenu.outline-char:

The menu as it appears in the outline glyph view
------------------------------------------------

* :ref:`MM Reblend <mmmenu.Reblend>`

--------------------------------------------------------------------------------

* :ref:`View <mmmenu.View>`

--------------------------------------------------------------------------------

* <sub font names>

.. _mmmenu.Reblend:

.. object:: MM Reblend

   Reblends the default version of the current glyph

.. _mmmenu.View:

.. object:: View

   A submenu which allows you to choose which of the designs of this glyph you
   want displayed in the background of the view

--------------------------------------------------------------------------------

.. object:: <sub font name>

   Clicking on a different sub font name in the menu will cause the glyph from
   that sub-font to be displayed instead of the current one. The subfonts are
   the master designs and the default blended font.
