# Textractor-Textract-Helper
amazon-textract-helper provides a collection of ready to use functions and sample implementations to speed up the evaluation and development for any project using Amazon Textract.
It installs a command line tool called ```amazon-textract```
# Install
```bash
> python -m pip install amazon-textract-helper
```
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)
# Test
```bash
> amazon-textract --help
usage: amazon-textract [-h] (--input-document INPUT_DOCUMENT | --example | --stdin) [--features {FORMS,TABLES} [{FORMS,TABLES} ...]]
[--pretty-print {WORDS,LINES,FORMS,TABLES} [{WORDS,LINES,FORMS,TABLES} ...]]
[--pretty-print-table-format {csv,plain,simple,github,grid,fancy_grid,pipe,orgtbl,jira,presto,pretty,psql,rst,medi
awiki,moinmoin,youtrack,html,unsafehtml,latex,latex_raw,latex_booktabs,latex_longtable,textile,tsv}]
[--overlay {WORD,LINE,FORM,KEY,VALUE,TABLE,CELL} [{WORD,LINE,FORM,KEY,VALUE,TABLE,CELL} ...]]
[--pop-up-overlay-output] [--overlay-output-folder OVERLAY_OUTPUT_FOLDER] [--version] [--no-stdout] [-v | -vv]
optional arguments:
-h, --help show this help message and exit
--input-document INPUT_DOCUMENT
s3 object (s3://) or file from local filesystem
--example using the example document to call Textract
--stdin receive JSON from stdin
--features {FORMS,TABLES} [{FORMS,TABLES} ...]
features to call Textract with. Will trigger call to AnalyzeDocument instead of DetectDocumentText
--pretty-print {WORDS,LINES,FORMS,TABLES} [{WORDS,LINES,FORMS,TABLES} ...]
--pretty-print-table-format {csv,plain,simple,github,grid,fancy_grid,pipe,orgtbl,jira,presto,pretty,psql,rst,mediawiki,moinmoin,youtrac
k,html,unsafehtml,latex,latex_raw,latex_booktabs,latex_longtable,textile,tsv}
which format to output the pretty print information to. Only effects FORMS and TABLES
--overlay {WORD,LINE,FORM,KEY,VALUE,TABLE,CELL} [{WORD,LINE,FORM,KEY,VALUE,TABLE,CELL} ...]
defines what bounding boxes to draw on the output
--pop-up-overlay-output
shows image with overlay
--overlay-text shows image with WORD or LINE text overlay. When both WORD and LINE overlay are specified, WORD text will be overlayed
--overlay-confidence shows image with confidence overlay
--overlay-output-folder OVERLAY_OUTPUT_FOLDER
output with bounding boxes to folder
--version print version information
--no-stdout no output to stdout
-v >=INFO level logging output to stderr
-vv >=DEBUG level logging output to stderr
```
# Sample Commands
## Easy Start
```bash
> amazon-textract --example
```
this will run the examples document using the DetectDocumentText API.
Output will be printed to stdout and look similar to this:
```json
{"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
```bash
> amazon-textract --input-document "s3://somebucket/someprefix/someobjectname.png"
```
Output similar to Easy Start
## Call with document on local file system
```bash
> 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 <location>.
## Call with STDIN
```bash
# 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
```bash
> 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
```bash
> amazon-textract --example --features TABLES --pretty-print TABLES
```
Output will look like this:
```text
|------------|-----------|---------------------|-----------------|-----------------------|
| | | 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:
```bash
> amazon-textract --example --features FORMS TABLES --pretty-print FORMS TABLES
```
will output
```text
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'.
```bash
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'.
