#1268 confirmed change

Switch to ttf fonts in SDL port

Description (last modified by noz)

Some of the SDL fonts don't support the new character used for the floor glyph (the dot) and many more don't support Latin-1 characters, which breaks xchars.

Given that there are currently a ton of these fonts, and that most users will assume that the size of a font shouldn't change it's appearance, I think we should do at least one of the following:

  1. prune or update the "bad" fonts
  1. separate out the different font faces (serif, sans) and styles (bold) from the size (making sure that we can support bold/non-bold versions of the different fonts)
  1. move to truetype fonts for SDL which can be displayed at different point sizes.

I am not a font expert so maybe I have misused some of the font terms, but I think the point should be clear.

  • Keywords font removed
  • Milestone changed from Triage to 4.0
  • Status changed from new to confirmed
  • Summary changed from Some SDL fonts are bad to Switch to ttf fonts in SDL port
  • Type changed from bug to change

Not confirmed: all SDL fonts support both xchars and centred dots IME. Changing this ticket to an aspiration to use sdl-ttf. (In the meantime, point 2 can be dealt with in #1267).

I think Sangband (which is SDL-only) handles TTFs, so we could look at that implementation.

we already use sdl-ttf2 -- just need a UI for selecting font sizes for TTF fonts.

  • Milestone changed from 4.0 to 3.5.0

Missed this one, but it's not an "experimental" issue.

  • Description modified (diff)

I'm going to stick my neck out here, and argue against using TTF fonts (under some circumstances). Hard-coded font sizes cannot be beaten for sheer readable information density, particularly in the small sizes. When you only have say 5 pixels by 9 pixels, no amount of clever scaling of a single glyph will do better than a pixel-optimised arrangement.

I've still not got rid of the old X-fonts on my system for precisely that reason - I can get about 25% more on the screen using them.

(Damn, that was meant to be a comment, not a Description change...)
