Set text size

[memeplex]

Is there any way to set text size inside a canvas, other than calling text() explicitly?

There is no relevant style and set text(size: ...) inside the canvas will fail because its result is of incorrect type.

Thanks!

You can set text outside of the canvas but if you want to change it within the canvas you would have to set it for each content function due to how scopes work in Typst.

To save a bit of time you could write a wrapper function that applies the styling you want:

#import "@preview/cetz:0.2.2"

#cetz.canvas({
  import cetz.draw: *

  let my-content(a, b, ..rest) = {
    content(
      a,
      {
        set text(size: 20pt)
        b
      },
      ..rest
    )
  }

  content((), [hello])
  my-content((rel: (2,0)), [hello])
})
