Getting started¶

This page installs the package and applies it to a short excerpt of lecture notes, introducing the main concepts one at a time: presets, intensity and seed, themes, and decorations.

Installation¶

#import "@preview/lookscanned:0.1.0"

git clone https://github.com/kornstein/lookscanned
cd lookscanned
just install-local

#import "@local/lookscanned:0.1.0"

The import binds the module lookscanned. All functions are accessed through it.

1. The source document¶

#set page(width: 12cm, height: 7cm, margin: (x: 1cm, y: 0.9cm))
#set text(font: "New Computer Modern", size: 10pt)
#set par(justify: true)

= Cauchy sequences

A sequence $(u_n)$ of real numbers is a _Cauchy sequence_ if for every
$epsilon > 0$ there exists $N in NN$ such that $abs(u_p - u_q) <= epsilon$
for all $p, q >= N$.

*Theorem 1.4.* A real sequence converges if and only if it is a Cauchy
sequence. In particular, for $abs(q) < 1$,
$ sum_(n=0)^infinity q^n = 1 / (1 - q). $

2. Apply a preset¶

scan is a show rule applied to the rest of the document. Place it after your own set page rules:

#import "@preview/lookscanned:0.1.0"

#set page(width: 12cm, height: 7cm, margin: (x: 1cm, y: 0.9cm))
#show: lookscanned.scan.with(preset: "office-scan")

The page now has grain, an edge shadow and dust; the text is slightly rotated and inked. Line breaks are unchanged and the text, including the equations, remains selectable.

3. Scale and vary the effect¶

#show: lookscanned.scan.with(preset: "office-scan", seed: 7, intensity: 1.6)

4. Override individual settings¶

Settings are grouped in themes: paper, stains, ink, skew, edges, scanner and quality. Each theme is a dictionary; keys you omit keep the preset's value.

#show: lookscanned.scan.with(
  preset: "office-scan",
  seed: 7,
  intensity: 1.6,
  paper: (color: rgb("#f3ead6"), aging: 0.4),
  ink: (bleed: 0.6),
)

Unknown themes, unknown keys and values of the wrong type stop compilation with an error naming the offending setting.

5. Add a decoration¶

Decorations are ordinary functions that return content. at places them relative to the current container instead of inline:

#lookscanned.stamp("Library copy", color: rgb("#5b3a8c"), at: (x: 62%, y: 76%), size: 10pt)

Next steps¶

• Compare the presets and pick the closest look.
• Read Mathematics before applying the package to a full set of notes or a book template.
• The Themes reference lists every setting.
