Sample Commands

Easy Start

> amazon-textract --example

this will run the examples document using the DetectDocumentText API. Output will be printed to stdout and look similar to this:

{"DocumentMetadata": {"Pages": 1}, "Blocks": [{"BlockType": "PAGE", "Geometry": {"BoundingBox": {"Width": 1.0, "Height": 1.0, "Left": 0.0
, "Top": 0.0}, "Polygon": [{"X": 9.33321120033382e-17, "Y": 0.0}, {"X": 1.0, "Y": 1.6069064689339292e-16}, {"X": 1.0, "Y": 1.0}],
"HTTPHeaders": {"x-amzn-requestid": "12345678-1234-1234-1234-123456789012", "content-type": "a
pplication/x-amz-json-1.1", "content-length": "48177", "date": "Thu, 01 Apr 2021 21:50:29 GMT"}, "RetryAttempts": 0}}

It is working.

Call with document on S3

> amazon-textract --input-document "s3://somebucket/someprefix/someobjectname.png"

Output similar to Easy Start

Call with document on local file system

> amazon-textract --input-document "./somepath/somefilename.png"

Output similar to Easy Start

We will continue to use the --example parameter to keep it simple and easy to reproduce. S3 and local files work the same way, just instead of --example use --input-document .

Call with STDIN

# first create JSON
amazon-textract --example > example.json
# now use a stored JSON with the ```amazon-textract``` command
cat example.json | amazon-textract --stdin -pretty-print LINES

Call with FORMS and TABLES

> amazon-textract --example --features FORMS TABLES

This will call the [AnalyzeDocument API] (https://docs.aws.amazon.com/textract/latest/dg/API_AnalyzeDocument.html) and output will include Output will look similar to "Easy Start" but include FORMS and TABLES information

Pretty print the output

Pretty print outputs nicely formatted information for words, lines, forms or tables.

For example to print the tables identified by Amazon Textract to stdout, use

> amazon-textract --example --features TABLES --pretty-print TABLES

Output will look like this:

|------------|-----------|---------------------|-----------------|-----------------------|
|            |           | Previous Employment | History         |                       |
| Start Date | End Date  | Employer Name       | Position Held   | Reason for leaving    |
| 1/15/2009  | 6/30/2011 | Any Company         | Assistant Baker | Family relocated      |
| 7/1/2011   | 8/10/2013 | Best Corp.          | Baker           | Better opportunity    |
| 8/15/2013  | present   | Example Corp.       | Head Baker      | N/A, current employer |

to pretty print both, FORMS and TABLES:

> amazon-textract --example --features FORMS TABLES --pretty-print FORMS TABLES

will output

Phone Number:: 555-0100
Home Address:: 123 Any Street, Any Town, USA
Full Name:: Jane Doe
Mailing Address:: same as home address
|------------|-----------|---------------------|-----------------|-----------------------|
|            |           | Previous Employment | History         |                       |
| Start Date | End Date  | Employer Name       | Position Held   | Reason for leaving    |
| 1/15/2009  | 6/30/2011 | Any Company         | Assistant Baker | Family relocated      |
| 7/1/2011   | 8/10/2013 | Best Corp.          | Baker           | Better opportunity    |
| 8/15/2013  | present   | Example Corp.       | Head Baker      | N/A, current employer |

Overlay

At the moment overlay only works with images, we will add support for PDF soon.

The following command runs DetectDocumentText, pretty prints the WORDS in the document to stdout and draws bounding boxes around each WORD and displays the result in a popup window and stores it to a folder called 'overlay-output-folder-name'.

amazon-textract --example --pretty-print WORDS --overlay WORD --pop-up-overlay-output --overlay-output-folder overlay-output-folder-name

The following command runs AnalyzeDocument for FORMS and TABLES, pretty prints FORMS and TABLES to to stdout and draws bounding boxes around each TABLE-CELL and FORM KEY/VALUE and displays the result in a popup window and stores it to a folder called 'overlay-output-folder-name'.

> amazon-textract --example --features TABLES FORMS --pretty-print FORMS TABLES --overlay FORM CELL --pop-up-overlay-output --overlay-output-folder ../mywonderfuloutputfolderfordocs/

The following command draws bounding boxes around each WORD, overlays the detected WORD text, and displays the result in a popup window and stores it to a folder called 'overlay-output-folder-name'.

> amazon-textract --example --overlay WORD --overlay-text --pop-up-overlay-output --overlay-output-folder overlay-output-folder-name

The following command draws bounding boxes around each LINE, overlays LINE text along with percentage confidence of the detected LINE text, and displays the result in a popup window and stores it to a folder called 'overlay-output-folder-name'.

> amazon-textract --example --overlay LINE --overlay-text --overlay-confidence --pop-up-overlay-output --overlay-output-folder overlay-output-folder-name
