Pos and offset property of mark in CeTZ

Questions

Hi. I want to shift the mark to the middle point of the line attached. And I have tried the following codes

#import "@preview/cetz:0.4.2"
#cetz.canvas(length: 3cm, {
  import cetz.draw: *
  line((0, 1), (3, 1), mark: (end: ">>", offset: 0%))

  line((0, 0), (3, 0), mark: (end: ">>", offset: 50%))
})

however it produced

16880fc88c0515225aad18b61be3018e
16880fc88c0515225aad18b61be3018e551×223 4.36 KB

This shows that not only is the mark placed in the middle, but the rest of the line is also not drawn. is this a intended feature or a bug?

Hi! I guess this is the desired behaviour.

If you don’t want the line to be shortened, pass/set shorten-to: none.


#import "@preview/cetz:0.4.2"
#cetz.canvas(length: 3cm, {
  import cetz.draw: *
  line((0, 1), (3, 1), mark: (end: ">>", offset: 0%))
  line((0, 0), (3, 0), stroke: red, mark: (end: ">>", offset: 50%))
  line((0, -1), (3, -1), stroke: green, mark: (
    end: ">>",
    offset: 50%,
    shorten-to: none, // 👈 Here
  ))

  // Alternatively
  set-style(mark: (shorten-to: none))
})

shorten-to

int or auto or none

Default: auto

Which mark to shorten the path to when multiple marks are given. auto will shorten to the last mark, none will shorten to the first mark (effectively disabling path shortening). An integer can be given to select the mark’s index.
