If you for instance load a font with T1lib, and then draw with
: more than one size, there will be lots of cached data for *every* size you've
: rendered glyphs in. This can be "fixed" by turning caching off (very bad for
: performance), or by deleting the font size information at certain points
What's the T1lib call to disable caching? What about for deleting
all size info?
. I looked briefly into
: creating a patch for it that allocated pools of 8KB, and returned pointers to
: blocks within that pool for each allocation, and that speeded things up a lot,
: and helped memory use tremendously (the allocations in question only happen
: when a font is loaded, and the free()'s only happen when it's unloaded), but I
: never got around to cleaning up those patches... I'd be happy to give pointers
: if someone wish to have a go at it, though.
Any more info you can give me would be great. I quickly toured the T1lib
source, but haven't had time to really get into it; too many other things on my
plate ;-)
Regards,
Greg
