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_typeString

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.

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

  • 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.

Returns:

  • (String)

#pageInteger

The page on which a block was detected. Page is returned by asynchronous operations. Page values greater than 1 are only returned for multipage documents that are in PDF format. A scanned image (JPEG/PNG), even if it contains multiple document pages, is considered to be a single-page document. The value of Page is always 1. Synchronous operations don't return Page because every input document is considered to be a single-page document.

Returns:

  • (Integer)

#relationshipsArray<Types::Relationship>

A list of child blocks of the current block. For example, a LINE object has child blocks for each WORD block that's part of the line of text. There aren't Relationship objects in the list for relationships that don't exist, such as when the current block has no child blocks. The list size can be the following:

  • 0 - The block has no child blocks.

  • 1 - The block has child blocks.
