Date: Thu, 18 Aug 2005 11:31:05 +0200 (CEST) Hi I've been thinking on how we could add support for multiple fonts within Rockbox the best possible way. To allow users to fully customize fonts all over the UI, including having multiple ones present on the same screen (the WPS being the most notable case). This is just my thoughts. Feel free to brainstorm, provide your own ideas or just extend mine. How about something like the following? We have a font cache with named fonts (like "uwe-prop14", "chicago12" and "alt6x10"). The cache fits N fonts, where N must be at least the number of simultaneous fonts we support (which _could_ be dynamic so that we support 6 small fonts or 2 big ones etc). Internally, we have a long list of font ID to font name mappings. Like FONT_RADIO FONT_DIRBROWSE FONT_MENU Each of these can be set to a specific font name by the user (through a config file). Of course, if a font is to be used that isn't already in the cache, it will get loaded into the cache from disk (and the least recently used font gets discarded from the cache if the new one doesn't fit). The system built-in font has its own font name (like "default" or so) which means that using that won't occupy space in the font cache at all. For the WPS screen, I imagine what we have multiple symbolic names that could be used like: FONT_WPS1 FONT_WPS2 FONT_WPS3 FONT_WPS4 ... and let's assume that WPS1 is the smallest and WPS4 is the biggest. Using this, a WPS designer can use 4 sizes, while a user of such a WPS can still elect exactly what fonts to use for those sizes. More thoughts: Italic/Bold - shall we support such styles to a given font or shall we just force users to just specify a font with these characteristics instead? These styles can get made on a font run-time and thus not wasting any extra space for them, but is it worth the extra code? -- Daniel Stenberg -- http://www.rockbox.org/ -- http://daniel.haxx.se/ _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockboxReceived on 2005-08-18 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
