length自始可用

A size or distance, possibly expressed with contextual units.

Typst supports the following length units:

Points: 72pt
Millimeters: 254mm
Centimeters: 2.54cm
Inches: 1in
Relative to font size: 2.5em

You can multiply lengths with and divide them by integers and floats.

Example


#rect(width: 20pt)
#rect(width: 2em)
#rect(width: 1in)

#(3em + 5pt).em \
#(20pt).em \
#(40em + 2pt).abs \
#(5em).abs

Fields

abs: A length with just the absolute component of the current length (that is, excluding the em component).
em: The amount of em units in this length, as a float.

定义

`pt`0.7.0起可用

Converts this length to points.

Fails with an error if this length has non-zero em units (such as 5em + 2pt instead of just 2pt). Use the abs field (such as in (5em + 2pt).abs.pt()) to ignore the em component of the length (thus converting only its absolute component).

self.pt() → float

`mm`0.7.0起可用

Converts this length to millimeters.

Fails with an error if this length has non-zero em units. See the pt method for more details.

self.mm() → float

`cm`0.7.0起可用

Converts this length to centimeters.

Fails with an error if this length has non-zero em units. See the pt method for more details.

self.cm() → float

`inches`0.7.0起可用

Converts this length to inches.

Fails with an error if this length has non-zero em units. See the pt method for more details.

self.inches() → float

`to-absolute`0.11.0起可用

Resolve this length to an absolute length.
