I was using freetype 2.4 version in my embedded application for
rendering ttf files only. It uses about 12 KB heap size, when I set
FT_RENDER_POOL_SIZE to 4096 Bytes. But in freetype 2.6 ,it takes
around 20 KB heap size minimum. Here I could observe ,freetype 2.6
doesn't use raster_pool
Sorry for the late response.
I am a beginner at using FreeType and new to the concept of subpixel
hinting. I've read through most API references that seemed related,
but I am still not sure how should I use the library to attain RGB
(or RGBA?) bitmaps with glyphs hinted on the subpixel
