I shortened the above to this by eliminating some of the temp variables.
if (GetDisplayAspect() > (XJ_aspect * 0.97))
float pixNeeded = h_mm * XJ_aspect * ((float)dispw / w_mm);
dispxoff += (dispwoff - (int)pixNeeded) / 2;
dispwoff = (int)pixNeeded;
Seems to work correctly. I changed the "16:9 video on non-16:9 display"
accordingly as well with this:
if ((GetDisplayAspect() * 0.97) < XJ_aspect)
float pixNeeded = (w_mm / XJ_aspect) * ((float)disph / h_mm);
dispyoff += (disphoff - (int)pixNeeded) / 2;
disphoff = (int)pixNeeded;
I'm going to do some more testing and will commit this when I commit
some other stuff I've been working on.
