You mean, for example, the distance from the leftmost pixel of the 'A' to the leftmost pixel in the following glyph? My current thinking is that given the string 'AB' this distance would be the advance of 'A' - the x-offset of 'A' + the x-offset of 'B' + tracking + kerning +/- the inscrutable effect of hinting A&B +/- the anti-aliasing of A&B. OK the kerning is probably zero in this case and you could examine the font to find out. The tracking could well be zero but we don't really have a way of knowing - but assuming for now that it is zero - the effects of hinting and anti-aliasing alone would make it difficult to determine the advance by eye at 36pt, especially to a sub-pixel accuracy. How are you drawing the glyphs?
