PHP REST API for OMR Processing

Aspose.OMR for Cloud is a REST API that helps you to perform optical mark recognition in the cloud. We provide a series of SDKs. Along with that, you can get binaries to start working immediately and recognize various OMR forms.

Developers can embed optical recognition in any type of application to extract data from images of tests, exams, questionnaires, surveys, etc. In the repository you can find examples on how to start using Aspose.OMR API in your project.

OMR Processing Features

  • Perform recognition of scanned photos and images for OMR operations.
  • Ability to perform OMR on rotated & perspective (within 25 deg) photos.
  • Extract & recognize human-marked data from scanned tests, exams, surveys, etc.
  • Supports the export of OMR results to CSV file format.
  • Use textual markup to generate OMR templates, generate surveys, and test sheets.
  • Availability of GUI application for managing OMR templates.
  • Specify the number of OMR based questions & answers in the template.
  • Availability of GUI OMR editor as a cloud client.
  • Provide JSON rules to perform OMR answer grading.
  • Clip an area of interest from an image, save it as JPEG & perform OMR on it.
  • Perform highly accurate optical mark recognition (OMR).

Save OMR As

CSV

Read OMR Formats

JPEG, PNG, BMP, TIFF, PDF

Quickstart

You can perform tasks out of the box without writing a single line of code with our GUI client. You can also refer to the client documentation.

Using OMR Cloud API in your Php projects

This PHP package is automatically generated by the Swagger Codegen project:

  • API version: 1.1
  • Build package: io.swagger.codegen.languages.PhpClientCodegen

Requirements

PHP 5.6 and later

PHP 5.6/Windows:

  • Please make sure that local repository path and all paths of all required packages do not exceed maximum length of a path (usually 255 symbols).
  • Aspose.OMR for Cloud use Guzzle library to perform REST requests. Guzzle framework uses cURL (libcurl) as transport library. On windows platform you can face problems with accessing https resources depending on libcurl version you are using.
    • If you are using libcurl built with OpenSSL, you need to download CA Certificates and update your php.ini:
    ....
    [curl]
    curl.cainfo="<full path to cacert.pem file>"
    [openssl]
    openssl.cafile="<full path to cacert.pem file>"
    ...
    
    • If you are using libcurl built with WinSSL, you are ready to go becuase WinSSL uses windows certificates store

OpenSSL and WinSSL based libcurl versions can be downloaded from here. Just choose your platform (x86 or x64) and OpenSSL (look for ssl string in the file name) or WinSSL (look for winssl string in the file name)

Installation

Clone repository

Clone aspose-omr-cloud with submodules:

git clone https://github.com/aspose-omr-cloud/aspose-omr-cloud-php.git --recurse-submodules
