There are two methods I discovered:
text-size: get in layout reduce [
'origin 0 'text "example string"
] 'size
text-size: size-text f: make-face/size/spec 'text 1000x100 [
text: "example string"
]
I found the second operates faster.
I just remembered they give different results for height
(87x19 and 87x15) but I only needed width at the time I
wrote it. I haven't figured out why yet.
