I need a definition of 'shaping engine' for a piece that I'm writing and I've come up with a proposal. You savvy typographers and type designers will surely tear it apart and make evident all its flaws. Please do. The definition goes like this:
A ‘shaping engine’ or ‘text shaping engine’ is:
- a software library
- used by text processors and page layout applications
- which processes raw Unicode-compliant text (or plain text, for short)
- and applies to it parameters from the OpenType font in use
- in order to generate the typographic written chain.
