Overview

A ‘Block` represents items that are recognized in a document within a group of pixels close to each other. The information returned in a `Block` object depends on the type of operation. In text detection for documents (for example DetectDocumentText), you get information about the detected words and lines of text. In text analysis (for example AnalyzeDocument), you can also get information about the fields, tables, and selection elements that are detected in the document.

An array of ‘Block` objects is returned by both synchronous and asynchronous operations. In synchronous operations, such as DetectDocumentText, the array of `Block` objects is the entire set of results. In asynchronous operations, such as GetDocumentAnalysis, the array is returned over one or more responses.

Instance Attribute Details

#block_type ⇒ String

The type of text item that’s recognized. In operations for text detection, the following types are returned:

• PAGE - Contains a list of the LINE ‘Block` objects that are detected on a document page.

• WORD - A word detected on a document page. A word is one or more ISO basic Latin script characters that aren’t separated by spaces.

• LINE - A string of tab-delimited, contiguous words that are detected on a document page.

In text analysis operations, the following types are returned:

• PAGE - Contains a list of child ‘Block` objects that are detected on a document page.

• KEY_VALUE_SET - Stores the KEY and VALUE ‘Block` objects for linked text that’s detected on a document page. Use the ‘EntityType` field to determine if a KEY_VALUE_SET object is a KEY `Block` object or a VALUE `Block` object.

• WORD - A word that’s detected on a document page. A word is one or more ISO basic Latin script characters that aren’t separated by spaces.

• LINE - A string of tab-delimited, contiguous words that are detected on a document page.

• TABLE - A table that’s detected on a document page. A table is grid-based information with two or more rows or columns, with a cell span of one row and one column each.

• TABLE_TITLE - The title of a table. A title is typically a line of text above or below a table, or embedded as the first row of a table.

• TABLE_FOOTER - The footer associated with a table. A footer is typically a line or lines of text below a table or embedded as the last row of a table.

• CELL - A cell within a detected table. The cell is the parent of the block that contains the text in the cell.

• MERGED_CELL - A cell in a table whose content spans more than one row or column. The ‘Relationships` array for this cell contain data from individual cells.

• SELECTION_ELEMENT - A selection element such as an option button (radio button) or a check box that’s detected on a document page. Use the value of ‘SelectionStatus` to determine the status of the selection element.

• SIGNATURE - The location and confidence score of a signature detected on a document page. Can be returned as part of a Key-Value pair or a detected cell.

• QUERY - A question asked during the call of AnalyzeDocument. Contains an alias and an ID that attaches it to its answer.

• QUERY_RESULT - A response to a question asked during the call of analyze document. Comes with an alias and ID for ease of locating in a response. Also contains location and confidence score.

The following BlockTypes are only returned for Amazon Textract Layout.

• ‘LAYOUT_TITLE` - The main title of the document.

• ‘LAYOUT_HEADER` - Text located in the top margin of the document.

• ‘LAYOUT_FOOTER` - Text located in the bottom margin of the document.

• ‘LAYOUT_SECTION_HEADER` - The titles of sections within a document.

• ‘LAYOUT_PAGE_NUMBER` - The page number of the documents.

• ‘LAYOUT_LIST` - Any information grouped together in list form.

• ‘LAYOUT_FIGURE` - Indicates the location of an image in a document.

• ‘LAYOUT_TABLE` - Indicates the location of a table in the document.

• ‘LAYOUT_KEY_VALUE` - Indicates the location of form key-values in a document.

• ‘LAYOUT_TEXT` - Text that is present typically as a part of paragraphs in documents.

Returns:

• (String)

  include Aws::Structure
end

#page ⇒ Integer

The page on which a block was detected. ‘Page` is returned by synchronous and asynchronous operations. Page values greater than 1 are only returned for multipage documents that are in PDF or TIFF format. A scanned image (JPEG/PNG) provided to an asynchronous operation, even if it contains multiple document pages, is considered a single-page document. This means that for scanned images the value of `Page` is always 1.

Returns:

• (Integer)

#relationships ⇒ Array<Types::Relationship>

A list of relationship objects that describe how blocks are related to each other.
