Note that the dashes themselves are elliptical arcs as well (thus exactly precise even if magnified greatly).

the short dash is equal wherever it is on the curve. Left of that we see an ellipse showcasing precise dashing, notably the length of e.g. Top-right we see a LaTeX formula that has been converted to a path. In the bottom-right the word 'stroke' is being stroked and drawn as a path. You can observe a variety of styles and text decorations applied, as well as support for LTR/RTL mixing and complex scripts. Figure 1: top-left you can see text being fitted into a box, justified using Donald Knuth's linea breaking algorithm to stretch the spaces between words to fill the whole width.

See the example below in Figure 1 for an overview of the functionality. It can be considered a Cairo or node-canvas alternative in Go. Additionally, it has a text formatter and embeds and subsets fonts (TTF, OTF, WOFF, WOFF2, or EOT) or converts them to outlines. It has a wide range of path manipulation functionality such as flattening, stroking and dashing implemented.
