Polling Limitations

Setting	Parameter name	Default Value
Initial Delay Before Polling	initial_delay_seconds	2 seconds
Default Delay Between Calls	delay_sec	1.5 seconds
Polling Attempts Before Timeout	max_retries	80 retries

Using the sample below,
we are going to illustrate how to extract the data that we want using the Ruby Client Library.

Quick-Start

#
# Install the Ruby client library by running:
# gem install mindee
#

require 'mindee'

# Init a new client
mindee_client = Mindee::Client.new(api_key: 'my-api-key')

# Load a file from disk
input_source = mindee_client.source_from_path('/path/to/the/file.ext')

# Parse the file
result = mindee_client.parse(
  input_source,
  Mindee::Product::InternationalId::InternationalIdV2
)

# Print a full summary of the parsed data in RST format
puts result.document

# Print the document-level parsed data
# puts result.document.inference.prediction

Output (RST):

Field Types

Standard Fields

These fields are generic and used in several products.

Basic Field

Each prediction object contains a set of fields that inherit from the generic Field class.
A typical Field object will have the following attributes:

• value (String, Float, Integer, bool): corresponds to the field value. Can be nil if no value was extracted.
• confidence (Float, nil): the confidence score of the field prediction.
• bounding_box (Mindee::Geometry::Quadrilateral, nil): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.
• polygon (Mindee::Geometry::Polygon, nil): contains the relative vertices coordinates (Point) of a polygon containing the field in the image.
• page_id (Integer, nil): the ID of the page, always nil when at document-level.
• reconstructed (bool): indicates whether an object was reconstructed (not extracted as the API gave it).

Aside from the previous attributes, all basic fields have access to a to_s method that can be used to print their value as a string.

Classification Field

The classification field ClassificationField does not implement all the basic Field attributes. It only implements
value, confidence and page_id.

Note: a classification field's value is always a String`.

Date Field

Aside from the basic Field attributes, the date field DateField also implements the following:

• date_object (Date): an accessible representation of the value as a JavaScript object.

String Field

The text field StringField only has one constraint: it's value is a String (or nil).
