The ability to compare changes made to documents or images of documents is vital when working within a team or with clients. Quickly integrate multi-format document comparison technology using LEADTOOLS Zero-footprint Document Compare solution. This interactive comparison navigator allows user to step-thru insertions, deletions, and edits. Additionally, you have access to detailed comparison information such as page number and bounding box for the difference. Simply upload your files and click compare, then let the Document Compare tool leverage LEAD’s AI-enhanced OCR engine to instantly make all the differences visible.

Last year, as part of our 25 projects in 25 days, we created a MeteorJS app to perform OCR using the LEADTOOLS web services.

Introduction

This post describes how to use LEADTOOLS (Windows or Linux) in .NET Core to convert almost any image to a PNG. This service can be used to display non-standard files in any modern web browser without installing plug-ins or third party code on the client.

Background

If you follow this tutorial, the resulting project demonstrates a quick and easy way to use 3rd party C API in .NET Core using DLLImport. Specifically, this project uses LEADTOOLS DLL/SO C API in .NET Core to convert files to PNG. Native .NET Core support is not available now available in LEADTOOLS version 20. An updated blog post that uses NuGet packages has been published for version 20.

The latest update of LEADTOOLS V19 includes an MVC project using the LEADTOOLS DocumentViewer. Additionally, the services have been refactored so that the services configuration part of this paper is out of date and no longer applies. However, we have decided to continue to make this paper available because there is useful information on configuring CORS in IIS that applies to many different applications.

If you have any questions about how to use the LEADTOOLS DocumentViewer in an MVC application, please contact support@LEADTOOLS.com.

As part of the LEAD Technologies 25th anniversary, we are creating 25 projects in 25 days to celebrate LEAD's depth of features and ease of use. Today's project comes from Daoud.

This web application will scan documents and convert them to searchable PDF with OCR using LEADTOOLS Version 19.
