  • Re: Why FontCreator hardly used by professionals?

    FontCreator only creates TrueType fonts, which only use quadratic Béziers. Such curves are described by three points: two endpoints on the curve and a single control point off the curve. Remember conic sections from high school? That's the sort of things you can create with these. Kinda limiting. In practice, you have to have a lot of segments and control points, and it's really easy to get a curve kinked up and spend hours trying to get a smooth curve.

    Cubic Béziers (used in PostScript), however, are a very different thing. You have two off-curve control points to work with, allowing for much more complex shapes. These curves are supple, smooth. One of the best features is that it's trivial to set up a curve pivot (my term; I don't know the proper one, but mine is groovy) -- move a point on one side, and a paired point moves the opposite way, giving symmetry and smoothness. Literal counterpoint, for the musically-inclined. Adobe Illustrator, InkScape and a lot of other vector drawing apps use these curves.

    In short, quadratic Béziers are much harder to work with. If you change a curve on, say, the rightmost point of /p, you have to move a lot of points to get the resulting curve to smoothly integrate. It's much, much easier with cubic Béziers.
    I have only edited fonts with Quadratic curves, and most likely will continue to do so, even though FontCreator can convert quadratic to cubic curves.


    After converting the quadratic S curve with 32 points to a cubic curve it had 62 points. Optimising it left 54. Manually deleting as many points as possible, and adjusting the curves manually using the background image (yellow) to maintain its original shape, I managed to reduce it to 36 points. Still 4 more than the Quadratic curve.  The difference arises because a quadratic curve can have only one off-curve point between two on-curve points, but it can also have two or more. It is having more than two off-curve points that leads to kinks in curves. 



    Be gentle with me, as I have precious little vector drawing experience with different programs, and don't understand the subtle differences between quadratic and cubic curves. 

    However, it seems to me that neither is any more difficult to use than the other to get smooth curves without kinks. It is just a matter of which one you have the most experience with using.

    It is entirely the developer's choice and decision what software they develop, and for which platforms. The user has no right to tell them what they should or should not do. They can vote with their wallet, and buy whatever software best suits their needs and/or budget. 

    Software companies are businesses, not government institutions, and have no obligation to do anything at all if they think it won't maximise their profits. 

    I am weary of Linux, Mac, or Android users berating Windows software developers for not developing versions for their platforms. If they thought it would be profitable, they would do it. If not, why on earth should they? It works the other way too. Why on earth should Mac developers employ a team of programs who know Windows programming, when their expertise is with Mac software? 
  • Re: Horizontal stroke in Latin Extended characters

    Bodoni, Caslon, and Baskerville all look wrong to me. IMO they should use the light horizontal stroke to match other horizontal strokes.

    Bhikkhu, it's the fall-back font.
    Thanks. That's what I assumed, so why does your forum font need to support every language under the sun?
