I have a CeTZ diagram I want to include in different documents with different font sizes. I used the suggestions from How to resize an included cetz/fletcher chart in a figure to a specific width? to try and scale it.
Unfortunately, the font also gets adjusted and is now too small to be legible. How can I best work around this problem?
#import "@preview/cetz:0.5.2": *
#let label(pos, anchor, body) = draw.content(pos, anchor: anchor, padding: 0.15, body)
#let trigo() = {
canvas({
import draw: *
line((0, 0), (2, 0), name: "a")
label("a", "north", $a$)
line((2, 0), (2, 2), name: "g")
label("g", "west", $g$)
line((0, 0), (2, 2), name: "h")
label("h", "south", $h$)
set-style(stroke: (paint: black))
angle.angle("a.start", "a.end", "h.end", radius: 40%, label: $alpha$)
angle.angle("g.start", "g.end", "a.start", label: $dot$)
})
}
#trigo()
#set text(size: 3pt)
#trigo()
#scale(50%, reflow: true, trigo())
You can use the optional argument “length” of canvas, it fixes the length of 1 unit. Contrary to “scale”, you don’t get specific width, you just scale the width by a multiplier. Example :
#import "@preview/cetz:0.5.2": *
#let label(pos, anchor, body) = draw.content(pos, anchor: anchor, padding: 0.15, body)
#let trigo(scale) = {
canvas(
length: scale*1cm,
{
import draw: *
line((0, 0), (2, 0), name: "a")
label("a", "north", $a$)
line((2, 0), (2, 2), name: "g")
label("g", "west", $g$)
line((0, 0), (2, 2), name: "h")
label("h", "south", $h$)
set-style(stroke: (paint: black))
angle.angle("a.start", "a.end", "h.end", radius: 40%, label: $alpha$)
angle.angle("g.start", "g.end", "a.start", label: $dot$)
})
}
#trigo(1)
#set text(size: 6pt)
#trigo(0.5)

As an addendum, here’s how I scaled a plot created with CeTZ-plot. Unfortunately, some elements don’t seem to work nicely, so I had to hard code values that look okay-ish for both sizes
#let horizontal-throw(scaling: 1) = {
canvas({
import draw: *
import calc: pow
let g = -9.81
let v_0 = 10
let h = 5
set-style(
stroke: (thickness: 0.1em),
mark: (length: 0.7em, width: 0.4em),
axes: (tick: (stroke: 0.1em, length: 1.3em)),
)
scale(scaling)
plot.plot(
size: (7, 6),
y-label: $h$,
axis-style: "left",
{
plot.add(domain: (0, 10.1), x => 1/2 * g * pow(x / v_0, 2) + h)
},
)
})
}
#horizontal-throw(scaling: 0.9)
#set text(size: 3pt)
#horizontal-throw(scaling: 0.23)
