To save as a screenshot instead, supply `screenshotOptions`.\nAll supported options can be viewed [here](https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-captureScreenshot).\n\n```js\nconst htmlPdf = require('html-pdf-chrome');\n\nconst html = 'Hello, world!
';\nconst options = {\n port: 9222, // port Chrome is listening on\n screenshotOptions: {\n format: 'png', // png, jpeg, or webp. Optional, defaults to png.\n // quality: 100, // Optional, quality percent (jpeg only)\n\n // optional, defaults to entire window\n clip: {\n x: 0,\n y: 0,\n width: 100,\n height: 200,\n scale: 1,\n },\n },\n // Optional. Options here: https://chromedevtools.github.io/devtools-protocol/tot/Emulation/#method-setDeviceMetricsOverride\n deviceMetrics: {\n width: 1000,\n height: 1000,\n deviceScaleFactor: 0,\n mobile: false,\n },\n};\n\nhtmlPdf.create(html, options).then((pdf) => pdf.toFile('test.png'));\n```\n\n### Using an External Site\n\n```js\nimport * as htmlPdf from 'html-pdf-chrome';\n\nconst options: htmlPdf.CreateOptions = {\n port: 9222, // port Chrome is listening on\n};\n\nconst url = 'https://github.com/westy92/html-pdf-chrome';\nconst pdf = await htmlPdf.create(url, options);\n```\n\n### Using Markdown\n\n```js\nimport * as htmlPdf from 'html-pdf-chrome';\nimport * as marked from 'marked';\n\nconst options: htmlPdf.CreateOptions = {\n port: 9222, // port Chrome is listening on\n};\n\nconst html = marked('# Hello [World](https://www.google.com/)!');\nconst pdf = await htmlPdf.create(html, options);\n```\n\n### Using a Template Engine\n\nPug (formerly known as Jade)\n\n```js\nimport * as htmlPdf from 'html-pdf-chrome';\nimport * as pug from 'pug';\n\nconst template = pug.compile('p Hello, #{noun}!');\nconst templateData = {\n noun: 'world',\n};\nconst options: htmlPdf.CreateOptions = {\n port: 9222, // port Chrome is listening on\n};\n\nconst html = template(templateData);\nconst pdf = await htmlPdf.create(html, options);\n```\n\n### HTTP Headers\n\nSpecify additional headers you wish to send with your request via `CreateOptions.extraHTTPHeaders`.\n\n```js\nconst options: HtmlPdf.CreateOptions = {\n port: 9222, // port Chrome is listening on\n extraHTTPHeaders: {\n 'Authorization': 'Bearer 123',\n 'X-Custom-Test-Header': 'This is great!',\n },\n};\n\nconst pdf = await HtmlPdf.create('https://httpbin.org/headers', options);\n```\n\n### Custom Headers and Footers\n\n_Note: Requires Chrome 65 or later._\n\nYou can optionally provide an HTML template for a custom header and/or footer.\n\nA few classes can be used to inject printing values:\n\n* `date` - formatted print date\n* `title` - document title\n* `url` - document location\n* `pageNumber` - current page number\n* `totalPages` - total pages in the document\n\nYou can tweak the margins with the `printOptions` of `marginTop`, `marginBottom`, `marginLeft`, and `marginRight`.\n\nAt this time, you must inline any images using [base64 encoding](http://www.bigfastblog.com/embed-base64-encoded-images-inline-in-html).\n\nYou can view how Chrome lays out the templates [here](https://cs.chromium.org/chromium/src/components/printing/resources/print_preview_page.html).\n\n#### Example\n\n```js\nconst pdf = await htmlPdf.create(html, {\n port,\n printOptions: {\n displayHeaderFooter: true,\n headerTemplate: `\n
