Invoice OCR Ruby
The Ruby OCR SDK supports the Invoice API.
Using the sample below, we are going to illustrate how to extract the data that we want using the OCR SDK.
Quick-Start
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::Invoice::InvoiceV4
)
# 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
,Boolean
): corresponds to the field value. Can benil
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, isnil
when at document-level. - reconstructed (
Boolean
): indicates whether or not 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.
Amount Field
The amount field AmountField
only has one constraint: its value is a Float
(or nil
).
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`.
Company Registration Field
Aside from the basic Field
attributes, the company registration field CompanyRegistrationField
also implements the following:
- type (
String
): the type of company.
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.
Locale Field
The locale field LocaleField
only implements the value, confidence and page_id base Field
attributes, but it comes with its own:
- language (
String
): ISO 639-1 language code (e.g.:en
for English). Can benil
. - country (
String
): ISO 3166-1 alpha-2 or ISO 3166-1 alpha-3 code for countries (e.g.:GRB
orGB
for "Great Britain"). Can benil
. - currency (
String
): ISO 4217 code for currencies (e.g.:USD
for "US Dollars"). Can benil
.
String Field
The text field StringField
only has one constraint: it's value is a String
(or nil
).
Taxes Field
Tax
Aside from the basic Field
attributes, the tax field TaxField
also implements the following:
- rate (
Float
): the tax rate applied to an item can be undefined. Expressed as a percentage. Can benil
. - code (
String
): tax code (or equivalent, depending on the origin of the document). Can benil
. - base (
Float
): base amount used for the tax. Can benil
.
Note: currently
TaxField
is not used on its own, and is accessed through a parentTaxes
object, an array-like structure.
Taxes (Array)
The Taxes
field represents an array-like collection of TaxField
objects. As it is the representation of several objects, it has access to a custom to_s
method that can render a TaxField
object as a table line.
Specific Fields
Fields which are specific to this product; they are not used in any other product.
Line Items Field
List of line item details.
A InvoiceV4LineItem
implements the following attributes:
description
(String): The item description.product_code
(String): The product code referring to the item.quantity
(Integer): The item quantitytax_amount
(Float): The item tax amount.tax_rate
(Float): The item tax rate in percentage.total_amount
(Float): The item total amount.unit_price
(Float): The item unit price.
