|
||
|
||
### AmazonTextractConverter
|
||
|
||
Converts documents to Haystack Documents using AWS Textract.
|
||
|
||
This component uses AWS Textract to extract text and optionally structured data
|
||
(tables, forms) from images and single-page PDFs.
|
||
|
||
When `feature_types` is not set, the component uses `DetectDocumentText` for
|
||
plain text OCR. When `feature_types` is set (e.g. `["TABLES", "FORMS"]`), it
|
||
uses `AnalyzeDocument` for richer structural analysis.
|
||
|
||
Natural-language queries are also supported via the `queries` parameter on
|
||
`run()`. When queries are provided, the `QUERIES` feature type is added
|
||
automatically and Textract returns answers extracted from the document.
|
||
|
||
Supported input formats: JPEG, PNG, TIFF, BMP, and single-page PDF (up to 10 MB).
|
||
|
||
AWS credentials are resolved via `Secret` parameters or the default boto3
|
||
credential chain (environment variables, AWS config files, IAM roles).
|
||
|
||
### Usage example
|
||
|
||
```python
|
||
from haystack_integrations.components.converters.amazon_textract import AmazonTextractConverter
|
||
|
||
converter = AmazonTextractConverter()
|
||
results = converter.run(sources=["document.png"])
|
||
documents = results["documents"]
|
||
```
|
||
|
||
#### __init__
|
||
|
||
```python
|
||
__init__(
|
||
*,
|
||
aws_access_key_id: Secret | None = Secret.from_env_var(
|
||
"AWS_ACCESS_KEY_ID", strict=False
|
||
),
|
||
aws_secret_access_key: Secret | None = Secret.from_env_var(
|
||
"AWS_SECRET_ACCESS_KEY", strict=False
|
||
),
|
||
aws_session_token: Secret | None = Secret.from_env_var(
|
||
"AWS_SESSION_TOKEN", strict=False
|
||
),
|
||
aws_region_name: Secret | None = Secret.from_env_var(
|
||
"AWS_DEFAULT_REGION", strict=False
|
||
),
|
||
aws_profile_name: Secret | None = Secret.from_env_var(
|
||
"AWS_PROFILE", strict=False
|
||
),
|
||
feature_types: list[str] | None = None,
|
||
store_full_path: bool = False,
|
||
boto3_config: dict[str, Any] | None = None
|
||
) -> None
|
||
```
|
||
|
||
Creates an AmazonTextractConverter component.
|
||
|
||
**Parameters:**
|
||
|
||
- **aws_access_key_id** (<code>Secret | None</code>) – AWS access key ID.
|
||
- **aws_secret_access_key** (<code>Secret | None</code>) – AWS secret access key.
|
||
- **aws_session_token** (<code>Secret | None</code>) – AWS session token.
|
||
- **aws_region_name** (<code>Secret | None</code>) – AWS region name. Must be a region that supports Textract.
|
||
- **aws_profile_name** (<code>Secret | None</code>) – AWS profile name from the credentials file.
|
||
- **feature_types** (<code>list\[str\] | None</code>) – List of feature types to detect when using AnalyzeDocument.
|
||
Valid values: "TABLES", "FORMS", "SIGNATURES", "LAYOUT".
|
||
If None, uses DetectDocumentText for basic text extraction.
|
||
The "QUERIES" feature type is managed automatically when the
|
||
`queries` parameter is passed to `run()`.
|
||
- **store_full_path** (<code>bool</code>) – If True, stores the complete file path in Document metadata.
|
||
If False, stores only the filename (default).
|
||
- **boto3_config** (<code>dict\[str, Any\] | None</code>) – Dictionary of configuration options for the underlying boto3 client.
|
||
Can be used to tune retry behavior, timeouts, and connection management.
|
||
|
||
#### warm_up
|
||
|
||
```python
|
||
warm_up() -> None
|
||
```
|
||
|
||
Initializes the AWS Textract client.
|
||
|
||
#### run
|
||
|
||
```python
|
||
run(
|
||
sources: list[str | Path | ByteStream],
|
||
meta: dict[str, Any] | list[dict[str, Any]] | None = None,
|
||
queries: list[str] | None = None,
|
||
) -> dict[str, Any]
|
||
```
|
||
|
||
Convert documents to Haystack Documents using AWS Textract.
|
||
|
||
**Parameters:**
|
||
|
||
- **sources** (<code>list\[str | Path | ByteStream\]</code>) – List of file paths or ByteStream objects to convert.
|
||
- **meta** (<code>dict\[str, Any\] | list\[dict\[str, Any\]\] | None</code>) – Optional metadata to attach to the Documents.
|
||
This value can be either a list of dictionaries or a single dictionary.
|
||
If it's a single dictionary, its content is added to the metadata of all produced Documents.
|
||
If it's a list, the length of the list must match the number of sources.
|
||
- **queries** (<code>list\[str\] | None</code>) – Optional list of natural-language questions to ask about each document.
|
||
When provided, the Textract `QUERIES` feature type is enabled
|
||
automatically and each question is sent as a query. Answers are
|
||
included in the raw Textract response. Example:
|
||
`["What is the patient name?", "What is the total due?"]`
|
||
|
||
**Returns:**
|
||
|
||
- <code>dict\[str, Any\]</code> – A dictionary with the following keys:
|
||
- `documents`: List of created Documents with extracted text as content.
|
||
- `raw_textract_response`: List of raw Textract API responses.
|
||
|
||
#### to_dict
|
||
|
||
```python
|
||
to_dict() -> dict[str, Any]
|
||
```
|
||
|
||
Serializes the component to a dictionary.
|
||
|
||
**Returns:**
|
||
|
||
- <code>dict\[str, Any\]</code> – Dictionary with serialized data.
|
||
|
||
#### from_dict
|
||
|
||
```python
|
||
from_dict(data: dict[str, Any]) -> AmazonTextractConverter
|
||
```
|
||
|
||
Deserializes the component from a dictionary.
|
||
|
||
**Parameters:**
|
||
|
||
- **data** (<code>dict\[str, Any\]</code>) – The dictionary to deserialize from.
|
||
|
||
**Returns:**
|
||
|
||
