How to create a PDF with Rotated Text & Images

Dynamically creating PDFs with rotated text and images is simple with DocRaptor's HTML to PDF API. You can use the same CSS transform properties typically used in web development, like this:

#text {
  transform: rotate(-30deg);
}

#image {
  transform: rotate(30deg);
}

This transforms the following HTML:

<div id="text">Rotate me!</div>
<div id="image"><img src="https://docraptor-production-cdn.s3.amazonaws.com/tutorials/raptor.png" /></div>

To see how it works with the DocRaptor HTML to PDF API in your programming language, check out the below rotated-content samples:

Select Your Language

Using DocRaptor's API

Below are the basics of using DocRaptor's HTTP API. It can easily be used in any programming language, but if we don't have a native agent for your language, please let us know! That'll help us write the best examples and agents.

The API key shown here, YOUR_API_KEY_HERE, actually works! Use it for testing without creating an account. The only requirement is test mode must be used (test parameter set to true).

To make documents, send a POST request to this URL:

https://YOUR_API_KEY_HERE@api.docraptor.com/docs

Send JSON-encoded API parameters (you'll need to set an HTTP header for Content-Type as application/json). These are the only required parameters:

{
  "type": "pdf",
  "document_content": "Hello World!"
}

Generating the Document with cURL

Here's a completely functional code sample for this tutorial:

cat <<-'DOCUMENT_OPTIONS' > docraptor_parameters.json
  {
    "test": true,
    "document_type": "pdf",
    "document_content": "<div id=\"text\">Rotate me!</div><div id=\"image\"><img src=\"https://docraptor-production-cdn.s3.amazonaws.com/tutorials/raptor.png\" /></div><style>#text {transform: rotate(-30deg);}#image {transform: rotate(30deg);}</style>"
  }
DOCUMENT_OPTIONS

curl https://YOUR_API_KEY_HERE@api.docraptor.com/docs \
  --fail --silent --show-error \
  --header "Content-Type:application/json" \
  --data @docraptor_parameters.json \
  > rotated-text-images.pdf

The DocRaptor JavaScript Library

The DocRaptor JavaScript library makes it easy to create PDFs with JavaScript. The library does not require jQuery, but you can use jQuery to define your document content. When a PDF is requested, the library constructs a hidden form and submits it to the DocRaptor API. The form is necessary to trigger the browser download window.

This library exposes your API key in your website source code. This code should never be used in a publicly-accessible location, instead try using our referrer-based API or a server-side agent such as PHP or Ruby.

JavaScript Example

<html>
  <head>
    <script src="https://docraptor.com/docraptor-1.0.0.js"></script>
    <script>
      var downloadDocumentFrom = function(selector) {
        // this key works in test mode!
        DocRaptor.createAndDownloadDoc("YOUR_API_KEY_HERE", {
          name: "rotated-text-images",
          test: true, // test documents are free but watermarked
          document_type: "pdf",
          document_content: document.querySelector(selector).innerHTML
          // document_url: "https://docraptor.com/examples/invoice.html",
          // javascript: true,
          // prince_options: {
          //   media: "print", // @media 'screen' or 'print' CSS
          //   baseurl: "https://yoursite.com", // the base URL for any relative URLs
          // }
        });
      };
    </script>
    <style>
      @media print {
        #download-button {
          display: none;
        }
      }
    </style>
  </head>
  <body>
    <div id="text">Rotate me!</div>
    <div id="image"><img src="https://docraptor-production-cdn.s3.amazonaws.com/tutorials/raptor.png" /></div>

    <style>
      #text {
        transform: rotate(-30deg);

      #image {

DocRaptor & Node.js

The best way to use DocRaptor with Node.js is directly through our HTTP API. In this example, we'll use the axios module, but you can obviously use any HTTP client you'd like.

Install the Axios Module

  <div id="image"><img src="https://docraptor-production-cdn.s3.amazonaws.com/tutorials/raptor.png" /></div>

  <style>
    #text {
      transform: rotate(-30deg);
    }

    #image {
      transform: rotate(30deg);
    }
  </style>
`;

config = {
  url: "https://api.docraptor.com/docs",
  method: "post",
  responseType: "arraybuffer", //IMPORTANT! Required to fetch the binary PDF
  headers: {
    "Content-Type": "application/json"
  },
  data: {
    user_credentials: "YOUR_API_KEY_HERE", // this key works in test mode!
    doc: {
      test: true, // test documents are free but watermarked
      document_type: "pdf",
      document_content: document_content
      // document_url: "https://docraptor.com/examples/invoice.html",
      // javascript: true,

      //   baseurl: "https://yoursite.com", // the base URL for any relative URLs
      //   }
    }
  }
};

axios(config)
  .then(function(response) {
    fs.writeFile("rotated-text-images.pdf", response.data, "binary", function(
      writeErr
    ) {
      if (writeErr) throw writeErr;
      console.log("Saved rotated-text-images.pdf!");
    });
  })
  .catch(function(error) {
    // DocRaptor error messages are contained in the response body
    // Since the response is binary encoded, let's decode
    var decoder = new TextDecoder("utf-8");
    console.log(decoder.decode(error.response.data));
