Barcode Reader

Barcode Reader

The PHP SDK supports the Mindee V1 Barcode Reader API.

Product Specifications

Specification	Details
Endpoint Name	barcode_reader
Recommended Version	v1.0
Supports Polling/Webhooks	❌ No
Support Synchronous HTTP Calls	✔️ Yes
Geography	🌐 Global

Quick-Start

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

Sample Code

<?php

use Mindee\Client;
use Mindee\Product\BarcodeReader\BarcodeReaderV1;

// Init a new client
$mindeeClient = new Client("my-api-key");

// Load a file from disk
$inputSource = $mindeeClient->sourceFromPath("/path/to/the/file.ext");

// Parse the file
$apiResponse = $mindeeClient->parse(BarcodeReaderV1::class, $inputSource);

echo $apiResponse->document;

Sample Output (rST)

Field Types

Standard Fields

These fields are generic and used in several products.

BaseField

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

• value (float|string): corresponds to the field value. Can be null if no value was extracted.

• confidence (float): the confidence score of the field prediction.

• boundingBox ([Point, Point, Point, Point]): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.

• polygon (Point[]): contains the relative vertices coordinates (Point) of a polygon containing the field in the image.

• pageId (integer): the ID of the page, always null when at document-level.

• reconstructed (bool): indicates whether an object was reconstructed (not extracted as the API gave it).

A Point simply refers to a list of two numbers ([float, float]).

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

StringField

The text field StringField implements the following:

• value (string): represents the value of the field as a string.

• rawValue (string): the value of the string as it appears on the document.

Attributes

The following fields are extracted for Barcode Reader V1:

Barcodes 1D

codes1D : List of decoded 1D barcodes.

foreach ($result->document->inference->prediction->codes1D as $codes1DElem)
{
    echo $codes1DElem->value;
}

Barcodes 2D

codes2D : List of decoded 2D barcodes.

foreach ($result->document->inference->prediction->codes2D as $codes2DElem)
{
    echo $codes2DElem->value;
}
