After almost four years of working on and off on an algorithmic approach to optically corrected obliques, the completely overhauled Italify is ready.
With the initial version of the plugin, which is still publicy available, I was running into too many issues due to the approach. It was using a basic slant/rotate mix, which deformed the height of outlines and lost horizontal extremes.
So I developed a completely new algorithm, which is purely geometry-based, without any rotation involved. That means: No stem info required, works with removed overlaps, and even works on quadratic curves if necessary (though not implemented yet). No nodes are removed/added, so master compatibility is guaranteed. Horizontal extremes are perfectly maintained. If you’re wondering about vertical vs. italic extremes, I recommend this Typedrawers topic.
Like the first Italify, curves are corrected as well as diagonal stems (think k, v, w, x…).
Currently, the algorithm is available on a service basis. The long-term goal is to make this a public Glyphs plugin, but there is still a very long way to go.
So, if you have a sans-serif font and can’t bear the thought of making your italics manually, here is your solution. Get in touch for pricing and further information.
