To use a custom font in Puppeteer running on an Ubuntu server, you will need to first upload the font file to the server. Once the font file is on the server, you can specify the path to the font file in your Puppeteer script. You can do this by using the fontFamily property in the page.pdf method and passing the path to the font file as one of the font-family values.

For example, if your custom font file is named "customFont.ttf" and is located in the same directory as your Puppeteer script, you can specify the font-family as follows:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

await page.pdf({
    path: 'output.pdf',
    format: 'A4',
    printBackground: true,
    displayHeaderFooter: true,
    headerTemplate: '<div></div>',
    footerTemplate: '<div></div>',
    margin: {
        top: '100px',
        bottom: '100px',
        left: '100px',
        right: '100px'
    },
    fontFamily: {
        'customFont': 'customFont.ttf'
    }
});

By specifying the font-family in this way, Puppeteer will be able to access and use the custom font when generating a PDF on the Ubuntu server.

What is the role of CSS in custom font rendering in puppeteer on Ubuntu?

CSS plays a crucial role in custom font rendering in puppeteer on Ubuntu. With CSS, you can define the font family, size, weight, and style for your text content. This allows you to use custom fonts in your puppeteer application and control how they are rendered on the page.

To include custom font rendering in puppeteer on Ubuntu, you can define the font-face rule in your CSS file, which specifies the font file location, format, and other properties. By using CSS, you can style your text content with the custom font and achieve the desired rendering results in your puppeteer application.

What is the benefit of using a Unicode font in puppeteer for rendering special characters on Ubuntu?

Using a Unicode font in puppeteer for rendering special characters on Ubuntu has several benefits:

1. Support for a wide range of characters: Unicode fonts support a vast range of characters from different languages and scripts, allowing you to render special characters accurately and consistently across different platforms.
2. Improved cross-platform compatibility: By using a Unicode font, you can ensure that your special characters will render correctly on different operating systems and devices, including Ubuntu.
3. Better text shaping and rendering: Unicode fonts are designed to handle complex text layout and shaping, ensuring that special characters are displayed correctly in various contexts and languages.
4. Enhanced user experience: Using a Unicode font for rendering special characters can improve the overall user experience by providing a visually appealing and consistent display of text, regardless of the content being rendered.

How to create a font mapping in puppeteer for Ubuntu?

To create a font mapping in Puppeteer for Ubuntu, you can follow these steps:

1. Install the necessary packages:

Make sure you have Puppeteer installed. If not, you can install it using npm:

1

npm install puppeteer

1. Create a new Puppeteer script:

Create a new JavaScript file for your Puppeteer script, for example font_mapping.js.

1. Use the fontMapping option:

In your Puppeteer script, use the fontMapping option to map specific fonts to their corresponding font files on your Ubuntu system. Here is an example of how you can use the fontMapping option in Puppeteer:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch({
    headless: true,
    fontMapping: {
      'Arial': '/path/to/Arial.ttf',
      'Times New Roman': '/path/to/times.ttf',
      'Verdana': '/path/to/verdana.ttf',
      // Add more font mappings as needed
    }
  });

  const page = await browser.newPage();
  await page.goto('https://www.example.com');

  // Your Puppeteer code here

  await browser.close();
})();

Replace /path/to/Arial.ttf, /path/to/times.ttf, and /path/to/verdana.ttf with the actual file paths of the font files on your Ubuntu system.

1. Run the Puppeteer script:

Run your Puppeteer script using Node.js:

1

node font_mapping.js

The Puppeteer script will now use the specified font mapping when rendering web pages in Ubuntu.

How to override default fonts with a custom font in puppeteer?

To override default fonts with a custom font in Puppeteer, you can use the font-family CSS property in combination with the page.addStyleTag method to inject custom styles into the page. Here's a step-by-step guide on how to do this:

1. First, you need to have the custom font file (e.g. a .woff or .ttf file) available in your project directory.
2. Use the page.addStyleTag method in Puppeteer to inject custom CSS styles that override the default fonts. Here's an example code snippet that shows how to do this:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  // Add custom font
  await page.addStyleTag({
    content: `
      @font-face {
        font-family: 'CustomFont';
        src: url('/path/to/custom-font.woff') format('woff');
      }
      
      body {
        font-family: 'CustomFont', sans-serif;
      }
    `
  });

  await page.goto('https://example.com');
  // Other Puppeteer actions

  await browser.close();
})();

1. In the CSS content passed to page.addStyleTag, define the @font-face rule to load the custom font file and set its font-family. Then, use the font-family property in your CSS rules to apply the custom font to specific elements on the page.
2. Make sure to replace '/path/to/custom-font.woff' with the correct path to your custom font file.
3. Run your Puppeteer script and verify that the custom font is applied to the elements on the page. You can also check the network tab in the browser's developer tools to ensure that the custom font file is loaded successfully.

By following these steps, you can override default fonts with a custom font in Puppeteer.

How to set font size and color in puppeteer with a custom font on Ubuntu?

To set font size and color in Puppeteer with a custom font on Ubuntu, you can follow these steps:

1. Install the custom font on your Ubuntu system: Download the font file (usually in .ttf or .otf format). Copy the font file to the fonts directory in your Ubuntu system. You can find the fonts directory at /usr/share/fonts or /usr/local/share/fonts. Update the font cache by running the command sudo fc-cache -f -v.
2. Use the custom font in your Puppeteer script: In your Puppeteer script, you can set the font family, size, and color using CSS styles. For example: const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.setContent(`

   Hello, world!

   `);
3. To make sure the custom font is loaded correctly in Puppeteer, you may need to update the Chromium settings to include the custom font. You can do this by passing additional arguments when launching Puppeteer: const browser = await puppeteer.launch({ args: ['--font-render-hinting=none', '--font-kerning=none'] });

By following these steps, you should be able to set the font size and color in Puppeteer with a custom font on Ubuntu.
