Basically I am using the filter ‘Round Corners’ but I am having a problem, some handles, even though they are not corners (green dots), don’t get straight. This is really unfortunate beause I don’t get a smooth curve.
Is there any plug-in to straighten up handles, If I manually nudge the handle it will get straight, but I wouldn’t want to to them one by one.
Some images so you can see what I am reffering too
That is an inherent problem of a rough grid and a situation where the handle is only a few units deep. If you have many small curves like that, you may want to set a finer grid, e.g. Set the subdivision to 100 in File > Font Info > Other Settings and try rounding again. A UPM of anything but 1000 in an OTF can cause problems.
with the grid subdivision I can fix them manually, because the points don’t snap to the grid. However I really would like something to straighten the handles… I did not run a simple ‘Round Corners’ I have three types of angles, and each has a different ‘round corner’ value. I manually did this to every single glyph. So it would be very time consuming to go back and do it all over again.
You know when you hit the arrow key on an handle and the tangent / smooth curves get straight? I would like something to do that in the whole font. Is there something like that?
It is in my scripts. But the problem is that the algorithm has no way of telling which is the correct handle and which one is at the wrong angle. The script just moves every handle a little bit to the side and back again.
Such a script would be useful to me too… how about assuming that the longer of the two handles is the correct one? That’s probably true in most cases (at least the ones that escape the designer’s eye).
No, and there are two reasons:
The way it is implemented is that it uses a method of a tool and that is only available in edit view.
And it shouldn’t, because you are supposed to check if the right handles are aligned. Because it has no way of knowing which handle is the correct one, and it could mess up your glyph significantly.
Postscript does not differentiate between corner and curve nodes. That is just a convenience in editing software. The finer grid remains in OTF/CFF fonts, but not in TTFs.
Depends on the design of course. The only technical problem I see is that it can mess up your hinting because your extremum points can get lost this way.
If you use an UPM of 1000, that means it is a thousandth of the font size. E.g. At 10pts, one unit is the equivalent of one hundredth of a point, or 0.01pt. I doubt it is visible in print. If it is your handle that is off by a unit, that means the curve deviance is even less than that, usually a quarter, i.e. 0.0025pt.
Again, print is not the problem then, but screen rendering could be because the curves may be missing extremum points.
I suppose you will be testing the typeface anyway?
