The extension allows drawing letters with a centerline – skeleton. The stroke is literary drawn by a nib led according to a skeleton. Letterink advantage is the ability to vary nib width and angle on the same skeleton and keep those variations while changing general nib preset for a master. Moreover, the stroke is rendered into a glyph as if it was an outline. This allows the designer to use strokes without the direct necessity to expand strokes to outlines.
Expanding to outlines generates clean vectors without messy points. Or, at least in most cases, it does so. The remaining cases are going to be fixed.
Currently, its possibility is narrowed to the simple pen simulated by abscissa. But, the results are more than promising.
