Re: [Devel] how to cope with bitmap glyphs?

[沈 狼]

hi, 

from the scratch,  for a give word, now I wannt to know how to render it.

so far, I know in the true type font  there is a cmap for us to lookup the 
glyphid corresponding to the word I want to render. so what's the usage of 
the bitmap if the EBDT,EBLC tables exist? someone has suggest me to read 
GDEF ,GSUB, GPOS table, but I dont yet know the relation between the bitmap 
& glyphid. would you give me a exaborative
