Feature request: text along path #12

Closed davidchall closed 4 years ago

davidchall commented 4 years ago

One feature that (I believe) is missing from the base grid package is the ability to render text along a curved path. There are quite a few use cases for this, but an example is https://github.com/tidyverse/ggplot2/issues/2946.

I found a matplotlib implementation on Stack Overflow (https://stackoverflow.com/a/44521963), but it quickly became clear that it's crucial to know the width of individual characters. This got me thinking that the gridtext package might be a good place to implement this?

I'm not really expecting a solution at any time, but just thought it might be something to keep in mind (especially since you mentioned elsewhere that you're planning to rewrite the rendering engine).

Sorry, this is out of scope. It requires an entirely different approach to text rendering. The next iteration of the rendering engine will focus on more complete HTML/CSS support. Text along a path is SVG, not HTML.

Fair enough - thanks for the tip!
