Generate a document with full height in Python with requests

In this guide, we'll show you how to generate a document with full height dynamically using Python and the requests library to convert them to PDF using PDFShift's API.

When you're converting a document, you might want to generate a document with full height dynamically. This can be done by setting the format parameter to the request and passing it a custom "auto" value for the {height} part.

import requests

# You can get an API key at https://pdfshift.io
api_key = 'sk_xxxxxxxxxxxx'

params = {
    'source': 'https://www.example.com',
    'format': '1280xauto'
}

response = requests.post(
    'https://api.pdfshift.io/v3/convert/pdf',
    auth=('api', api_key),
    json=params
)
response.raise_for_status()

with open('result.pdf', 'wb') as f:
    f.write(response.content)

print('The PDF document was generated and saved to result.pdf')

The format parameter can accept various values, such as 'Letter', 'Legal', 'Tabloid', 'Ledger', 'A0', 'A1', 'A2', 'A3', 'A4', 'A5'.

But it can also accept a custom values that is defined per the width and height as follow: {width}x{height}

Both width and height are pixel value by default, but if you precise the unit (in "cm", "mm", "in" or "pt"). That unit will be used instead.

For instance, you can set a format of:

{
    "source": "https://www.example.com",
    "format": "21cmx29,7cm"
}

Now, if you want a "liquid" height, which will analyze the height of the page and use it as your format, you can set the {height} value to auto. So, instead of setting a fixed height such as 'format': '1280x1024', you can set 'format': '1280xauto' and the height will be calculated based on the content of the page.
