Fetching PDF converted from DjVu
Contents
[
Hide
]
When a DjVu file is submitted for conversion, it is queued to ensure a stable response even under high load. To obtain the result, send a GET request to the https://api.aspose.cloud/v5.0/ocr/djvu2pdf Aspose.OCR Cloud REST API endpoint. To authorize the request, pass the access token in Authorization header (Bearer authentication).
Provide the unique identifier of the conversion task in id parameter:
curl --request GET --location 'https://api.aspose.cloud/v5.0/ocr/djvu2pdf?id=c4b60313-4f78-45f8-b708-069eb98dc22e' \
--header 'Accept: text/plain' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...HaRYOxBcCRCPLnrFCVXpw7UA' \
Conversion results
The resulting PDF document is returned in JSON format in the response body.
