Re: [ft-devel] rendering differences between 2.4.2 and 2.4.4

[Алексей Подтележников]

Werner,

All arches seem to have lost weight. It is possible that the conic
Bezier flattener
is not splitting enough. You may want to fiddle with line 900 in ftgrays.c

while ( dx > ONE_PIXEL / 4 )

make it

while ( dx > ONE_PIXEL / 6 )

But again, this is not the solution I like. I still think that both
cubic and conic flatteners
should use essentially the same code. Currently, the cubic solution is
actually controlling
the amount of error while doing the job, whereas the conic one is
trying to make the
best guess ahead of doing the job.

Best,
Alexei
