[Freetype] How to give starting address of charmap file to rasterizer?

[koffman Huang]

Hi!

 

I have a problem about charmap if font is CID like charmap not in font file.

 

I am writting a font driver for freetype2.1.2. The font format is not include charmap in same file.

 

In file system base loading font use api FT_New_Face, I  put the charmap file in same path,

 

so I can get the charmap file. If I load the font in memory use api  FT_New_Memory_Face, I can

 

give the api the font starting  address, but I am no idea to give  the  starting  address  of charmap to

 

rasterizer.  Please help me!
