[Interest] Modifying the font metrics ("leading" and "tracking") everywhere

[Atlant Schmidt]

Ruth:

  Thanks for your suggestions! Unfortunately for us:

    o It's not clear that the licensing of the font in question would allow
       us to make modifications to it. (It's a commercial font, not a FOSS
       font.)

    o FontForge doesn't successfully open the font.(1)

  I'll look more deeply into this.

 Everyone, please keep the suggestions coming!

(1) In older versions of FreeType+Qt, this font had trouble with
  "horizontal advance" values not being used correctly, but this
  was fixed at least as of Qt 4.8.3 and the then-current version
  of FreeType. As far as I know, I's being drawn accurately by
  Qt+FreeType, it just has too much leading for our purposes.

It sounds to me as if your best bet is to create a derived version of the font file with characteristics better suited to you. The open source program fontforge is a good starting point for such things, and leading is a simple thing to change with it.

It might be possible to load the font into memory and modify the in-memory copy but I doubt very much that this will be quick or easy let alone portable.

You should be able to use CSS ( Qt style parameters ) to modify line spacing and so on; such things are bread-and-butter of CSS anyway. Overall Inter-character spacing changes are a part of CSS3 IIRC and Qt may not honour such things, though you may be lucky. Modifying kerning is harder, and probably best left for fontforge.
