List,
I am looking at the following problem and hope that FreeType allows me
to implement a solution:
Office documents are created by our customers on Windows using fonts
that are available there. These document shall then be rendered by our
software on other platforms (such as Linux). When the original font is
missing, we currently use a replacement font that is available on the
destination platform.
The replacement font has different metrics, so line breaks and sometimes
even page breaks will vary (the Office files contain no linebreak
information; a paragraph is just a stream of characters). This is
something we wish to avoid. Breaks should be the same as on the PC the
documents have been created on.
My idea is to create a Multiple Master font with a "width" axis and
provide this as a replacement font. Our software would then use FreeType
to create a font instance from the Multiple Master font where each glyph
is individually scaled so that it mimics the width of the same character
in the original font.
As far as I can see, the FreeType API provides functions for creating
instances from Multiple Master fonts, but the same design vector is
applied to all characters.
Is it possible to apply individual design scalings to individual glyphs?
Note that this is not the same as just scaling glyphs. Such scaling
leads to unpleasant looks because the ratio of vertical and horizontal
stem widths is not preserved.
Any hints or ideas appreciated.
