QR Codes

Press can generate QR codes directly in documents. They're commonly used for business cards, event badges, and documents that need to link to online resources.

Basic Usage

<qr-code data="https://example.com/contact/jane-doe" />

The data attribute holds the content to encode -- typically a URL, but it can be any text.

Sizing

Control the size with width and height:

<qr-code data="https://example.com" width="80pt" height="80pt" />

Data-Driven QR Codes

Bind the QR code content to data:

<qr-code data="{{ data['profile-url'] }}" width="60pt" height="60pt" />

Conditional QR Codes

Show a QR code only when a URL is provided:

<qr-code show-if="data.website" data="{{ data.website }}"
          width="60pt" height="60pt" />

Example: A Business Card

<press>
  <document width="8.5cm" height="5.5cm" font-color="white" background-color="black">
    <repeat data="data.contacts" item="person">
      <page padding="0.5cm">
        <frame direction="row" height="100%" v-align="center">
          <frame width="fill" v-align="center">
            <frame font-size="12pt" font-style="bold">{{ person.name }}</frame>
            <frame font-size="9pt" font-color="#9EA7F0">{{ person.title }}</frame>
            <frame height="8pt" />
            <frame font-size="8pt" line-height="1.6">
              {{ person.email }}<br />
              {{ person.phone }}
            </frame>
          </frame>
          <frame show-if="person.url" width="fill" h-align="right" v-align="center">
            <qr-code data="{{ person.url }}" border-radius="0.2cm" padding="0.2cm" background-color="white" />
          </frame>
        </frame>
      </page>
    </repeat>
  </document>

  <data type="json">
  {
    "contacts": [
      {
        "name": "Jane Ashworth",
        "title": "Head of Operations",
        "email": "j.ashworth@example.com",
        "phone": "+44 7700 123456",
        "url": "https://example.com/team/jane-ashworth"
      },
      {
        "name": "Marcus Reed",
        "title": "Lead Developer",
        "email": "m.reed@example.com",
        "phone": "+44 7700 654321",
        "url": "https://example.com/team/marcus-reed"
      }
    ]
  }
  </data>
</press>

This generates one business card per contact, each with a QR code linking to their profile page.
