I’m curious about the difference between using the Slant option in RMX Tuner and manually adjusting slant with the Transform tool.
Are there any significant advantages to using one method over the other? For instance, does RMX Tuner handle the slanting process differently in terms of stem correction, precision or curve quality?
Stem correction: Neither the RMX Tuner nor Transformations/Slant perform any stem correction. Transformations/Cursify does, though.
Precision: The RMX Tuner is very precise in that it correctly handles slant figures with many decimal digits (say, if you want to slant by 7.29873 degrees). Plus, it applies the Harmonizer’s de-kinking and smart rounding, which give slightly less rounding error.
Curve quality: How would you define quality in this context?
The most significant difference is that the RMX Tuner retains extrema. In other words, it moves slanted extrema along the curve so as to become upright again. Naturally, this does not always lead to precisely the same shape as pure slanting, so you could argue that is is less precise (with respect to the slanted shape) than plain slanting. You may want to insert nodes before RMX-slanting so as to keep the shape closer to the pure slant.
