Amazon Textract Pipeline Component to add page dimensions to page block types
Project description
Textract-Pipeline-PageDimensions
Provides functions to add page dimensions with doc_width and doc_height to the Textract JSON schema for the PAGE blocks under the custom attribute in the form of:
e. g.
{'PageDimension': {'doc_width': 1549.0, 'doc_height': 370.0} }
Install
> python -m pip install amazon-textract-pipeline-pagedimensions
Make sure your environment is setup with AWS credentials through configuration files or environment variables or an attached role. (https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html)
Samples
Add Page dimensions for a local file
sample uses amazon-textract-caller amazon-textract-pipeline-pagedimensions
python -m pip install amazon-textract-caller
from textractpagedimensions.t_pagedimensions import add_page_dimensions
from textractcaller.t_call import call_textract
from trp.trp2 import TDocument, TDocumentSchema
j = call_textract(input_document='<path to some image file>')
t_document: TDocument = TDocumentSchema().load(j)
add_page_dimensions(t_document=t_document, input_document=input_file)
print(t_document.pages[0].custom['PageDimension'])
# output will be something like this:
# {
# 'doc_width': 1544,
# 'doc_height': 1065
# }
Using the Amazon Textact Helper command line tool with PageDimensions
Together with the Amazon Textract Helper and Amazon Textract Response Parser, we can build a pipeline that includes information about PageDimension and Orientation of pages as a short demonstration on the information that is added to the Textract JSON.
