Hello again!
I am still trying to work out some issues with glyph spacing and
vertical fonts. I have implemented the lsb/rsb_deltas for horizontal
text and that seems to be working fine. The issue I am now having is
with some Japanese fonts that are intended to be drawn vertically
with very little space between the glyphs. Essentially, the spacing
is really bad :( In some cases glyphs actually touch each other.
However, if I render with FT_LOAD_NO_HINTING then the spacing is
fine. I have some sample images here: http://www.ljug.com/
vertsamples.html
Specifically, note the text in red boxes for both the hinted and
unhinted versions. Since the hinting seems to matter, I was wondering
if this is just another case of rounding during auto-hinting causing
problems and if it can be solved with something analogous to lsb/
rsb_delta corrections. I made a feeble attempt to add tsb/bsb_delta
values to my local copy of FreeType, but it didn't seem to make a
difference. Of course, it is extremely likely I simply failed to
implement it properly. Does anyone have any ideas on how to fix the
spacing? Am I correct about the auto-hinting, or way off the mark? Is
this even the right mailing list to send this to? Help!
