Output from a PDF/TIFF request is written to a JSON file created in the specified Google Cloud Storage bucket.ġ) Upload a file to your Google Cloud StorageĢ) Make a POST request to perform PDF/TIFF document text detectionģ) Make a GET request to check if document text detection is done The Vision API can detect and transcribe text from PDF and TIFFĭocument text detection from PDF and TIFF must be requested using theĪsyncBatchAnnotate function, which performs an asynchronous request and provides its status using the operations resources. On April 6, 2018, support for PDF and TIFF files in document text detection was added to Google Cloud Vision API (see Release Notes). # including confidence scores and bounding boxes # annotation/pages/blocks/paragraphs/words/symbols # The response contains more information: # Here we print the full text from the first page. # The actual response for the first page of the input file.įirst_page_response = response.responsesĪnnotation = first_page_response.full_text_annotation Json_string = output.download_as_string() # Since we specified batch_size=2, the first response contains # Process the first output file from GCS.

This makes the JSON object quite unwieldy and very difficult to use. My issue is that the JSON file that is saved to GCS only contains bounding boxes and text for "symbols", i.e. Using their example code I am able to submit a PDF and receive back a JSON object with the extracted text. I am attempting to use the now supported PDF/TIFF Document Text Detection from the Google Cloud Vision API.
