Usage

tc_pdf handler route requires /pdf/ in URL after all filters but before the resource URL part e.g.

http://<thumbor_server>/unsafe/240x240/smart/pdf/localhost:8000/media/document/test.pdf

If you are using libthumbor to generate URLs then you can use this patch for CryptoURL class and then use it like this:

from crypto import CryptoURL

crypto = CryptoURL(key='my-security-key')

encrypted_url = crypto.generate(
    width=300,
    height=200,
    smart=True,
    image_url='/path/to/my/pdf_file.pdf',
    pdf=True, # <-- Pass this
)
