[ft-devel] character spacing

[Louis Desjardins]

In order to draw my text, I currently make calls to:

FT_Get_Char_Index

FT_Load_Glyph

FT_Render_Glyph

and then I store the bitmap of each ascii character to memory, so that once I actually render the character, I can simply call on the stored bitmap. 

The problem is that the character spacing is not correct. It looks like I need to use FT_Get_Kerning to correct this, however from the examples I've seen, it looks like I need to call this before FT_Load_Glyph, i.e. at the time when I am storing each of my characters. 

However, I have no idea what strings will be rendered, until runtime, so I don't know the 'left_glyph' and 'right_glyph' parameters in FT_Get_Kerning beforehand. Is there a way to make use of FT_Get_Kerning while drawing my bitmap (after I've already loaded the glyph and retrieved its bitmap), in order to achieve proper character spacing at runtime?

Thank-you
