--- Comment #3 from Eben Sorkin  ---
Do you think you can switch to using the Win values for clipping and the
typo values for linespacing instead?

fonts to test with

This font has diacritics above the letter A and below it to use to check for
clipping.

[calligrawords] [Bug 387687] New: font clipping

2017-12-07 Thread Eben Sorkin
https://bugs.kde.org/show_bug.cgi?id=387687

Bug ID: 387687
   Summary: font clipping
   Product: calligrawords
   Version: 3.0.0
  Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
  Severity: major
  Priority: NOR
 Component: general
  Assignee: calligra-words-bugs-n...@kde.org
  Reporter: sorkine...@gmail.com
  Target Milestone: ---

Fonts using the industry standard format for setting vertical metrics in fonts
clip in Calligrawords. This does not happen in Inkscape for instance. The
standard is one in which Hhea and Typo tables sum to the EM size of the font
(usually 1000 or 2048 units) and the Win values indicate how far not to clip.
Calligrawords must be using either the typo or the hhea values for both
linespacing and clipping. This is unusual and has a bad impact for usings of
eastern european, Asian, African, Indic, South Asian and Middle eastern
scripts.
