Extreme Nodes or Not

Robby Woodard's picture

I understand that "Nodes at Extremes" are a necessary part of hinting.

And though I do NOT understand the subtleties of hinting (I just click F7) putting nodes at extremes has broadly become the way I draw most curves anyway.

When my glyph has a broad curves at the extremes or corners that turn at the extremes, everything is honky dory...

But things don't always work out that way:

When I put nodes at the extremes of tiny curves (like in A,V and W glyphs with diagonals that have rounded edges) the curve gets wobbly.

Do I need to turn my UPM up to 2000 to handle the fidelity for these fine curves?

Or can I just not worry about it and let my nodes just be really close to the extremes in those few cases?

I DO plan to generate both OT type 1 and Truetype eventually...

Tiny curves don't need it and don't gain anything by it. Best practice is to put curve quality first and trust your common sense.

That is the approach I would like to take...

But I read somewhere that OpenType TT needed points on all the extremes or it had problems.

Is that not so much the case?
