Functions

from textractcaller import call_textract
def call_textract(input_document: Union[str, bytearray],
                  features: List[Textract_Features] = None,
                  output_config: OutputConfig = None,
                  kms_key_id: str = None,
                  job_tag: str = None,
                  notification_channel: NotificationChannel = None,
                  client_request_token: str = None,
                  return_job_id: bool = False,
                  force_async_api: bool = False) -> dict:

Also useful when receiving the JSON response from an asynchronous job (start_document_text_detection or start_document_analysis)

from textractcaller import get_full_json
def get_full_json(job_id: str = None,
                  textract_api: Textract_API = Textract_API.DETECT,
                  boto3_textract_client=None)->dict:

And when receiving the JSON from the OutputConfig location, this method is useful as well.

from textractcaller import get_full_json_from_output_config
def get_full_json_from_output_config(output_config: OutputConfig = None,
                                     job_id: str = None,
                                     s3_client = None)->dict:

Samples

Calling with file from local filesystem only with detect_text

textract_json = call_textract(input_document="/folder/local-filesystem-file.png")

Calling with file from local filesystem only detect_text and using in Textract Response Parser

(needs trp dependency through python -m pip install amazon-textract-response-parser)

import json
from trp import Document
from textractcaller import call_textract

textract_json = call_textract(input_document="/folder/local-filesystem-file.png")
d = Document(textract_json)

Calling with file from local filesystem with TABLES features

from textractcaller import call_textract, Textract_Features
features = [Textract_Features.TABLES]
response = call_textract(
    input_document="/folder/local-filesystem-file.png", features=features)

Call with images located on S3 but force asynchronous API

from textractcaller import call_textract
response = call_textract(input_document="s3://some-bucket/w2-example.png", force_async_api=True)

Call with OutputConfig, Customer-Managed-Key

from textractcaller import call_textract
from textractcaller import OutputConfig, Textract_Features
output_config = OutputConfig(s3_bucket="somebucket-encrypted", s3_prefix="output/")
response = call_textract(input_document="s3://someprefix/somefile.png",
                          force_async_api=True,
                          output_config=output_config,
                          kms_key_id="arn:aws:kms:us-east-1:12345678901:key/some-key-id-ref-erence",
                          return_job_id=False,
                          job_tag="sometag",
                          client_request_token="sometoken")

Call with PDF located on S3 and force return of JobId instead of JSON response

from textractcaller import call_textract
response = call_textract(input_document="s3://some-bucket/some-document.pdf", return_job_id=True)
job_id = response['JobId']
