I am using FreeType not to render to screen but just to rasterize a

That said should I be using FT_Set_Char_Size or FT_Set_Pixel_Sizes?
It doesn't matter. Both work the same.
As I am not rendering to screen, dpi does not matter in the
slightest bit.
Well, then use FT_Set_Pixel_Sizes.
Thanks for your reply.
I've only just started using FreeType so please excuse the level of
ignorance that I'm about to display. (I _have_ read the tutorial even
though my ignorance may suggest otherwise.)
I have used FT_Set_Pixel_Sizes( face , 32 , 32 ) -- because 32 by 32 is
the maximum font dimension of a font in my application. Upon inspection
of the resulting face->glyph I get a bitmap that's only about 25% of the
size specified in FT_Set_Pixel_Sizes (Bitmap details: rows = top = 22,
width = 13, left = 1). Of course I may have completely misunderstood
what FT_Set_Pixel_Sizes does. Please do correct me where my thinking or
understanding is incorrect.
Also, how is are the bitmap properties (rows, top and width) determined?
Are they partly based on some meta data the TTF font file or are they
_solely_ based on the user specified size?
