A path x points distant from the current path

[jdaw1]

Currently the likes of OutlineTitles and InlineTitles work as follows.

• As needed, clip;
• Loop, each pass setlinewidthing to a smaller value,strokeing in alternate loops white or black.

This imposes a large burden on printers, some of which cope slowly.

It would be much better if there were a function that made a path a certain distance from a pre-existing path. The new path could then be stroked black, with no painting of white.

This has been discussed on comp.lang.postscript:

• A path x points distant from the current path, May 2009;
• Fierce and scary geometry algorithm for ‘ParallelPath’, April 2019;
• Snipping the ears, Oct 2019.

Whence, no joy.

Edit:

• Classifying bezier curves, Oct 2022.
