4 Inkscape uses system fonts

     4 Text inside HMI designed with Inkscape may not display properly in web browser.

     5 --------------------------

     5 The reason is that Inkscape and targeted web browser may disagree on fonts support.

     7 Supported font types

     7 To keep HMI text design consistent, missing fonts can be added to project in order

     8 --------------------

     8 to have them served together with HMI so that web browser can support them.

    10 Fonts used by Inkscape

    11 ----------------------

    12 

    13 * System fonts

    14 

    15     Vector fonts available at system level are systematically available

    16     in Inkscape

    17 

    18 * User fonts

    19 

    20     When selected in Inkscape preferences, Inkscape also considers fonts

    21     from these sources:

    22 

    23     - "fonts" directory in Inkscape user's directory

    24 

    25     - arbitrary absolute font directories set by user 

    26 

    27     There is no way to point to a directory relative to the SVG file

    28     being edited.

    29     At the time of writing this documentation, Inkscape doesn't support

    30     embedding font in SVG file.

    31 

    32     User then have to regularly update Inkscape preferences to ensure

    33     that fonts used in currently edited design are available when editing

    34     it.
