Add Barcode Signature to your Documents

What is an Electronic Signature?

An electronic signature or e-signature refers to data in electronic form which is logically associated with other data in electronic form and which is used by the signatory to sign. This type of signature provides the same legal standing as a handwritten signature as long as it adheres to the requirements of the specific regulation. E-Signatures can be in the form of digital text, images, barcode, QR codes, etc.

Electronic signatures are a legal concept distinct from digital signatures, a cryptographic mechanism often used to implement electronic signatures. While an electronic signature can be as simple as a name entered in an electronic document, digital signatures are increasingly used in e-commerce and in regulatory filings to implement electronic signatures in a cryptographically protected way.

This option is ignored when either Height or Width options are set.

Width

The width of the output result in pixels.

Height

The height of the output result in pixels.

Guys! New version of Groupdocs.Comparison Cloud 19.5 is here. Your feedback and interest in our Document Comparison Cloud API keeps us motivated to implement new features. It is all new API; in this version we have implemented the API as a Microservice. It improves the performance and stability of the API. New API has less methods and options. We have also introduced new methods for cloud storage operations in GroupDocs.Comparison Cloud API. I will give you an overview of some of the new features in the following sections. For complete details of new features and enhancement, please check the release notes of this version.

New API Version

We have introduced V2 API Version in 19.5 version and following base URL will be used. Please note V1 will remain available.

https://api.groupdocs.cloud/v2.0/comparison/

Authentication

For improved security, we have introduced JWT(JSON Web Token) authentication in this release. OAuth2 and URL signing authentication methods are not supported any more by V2 API Version. Let us show you how to get JWT Access Token.

Storage APIs

Now onward, you do not need to use GroupDocs.Storage Cloud REST API for storage operations. GroupDocs.Comparison Cloud API has introduced following API methods for the purpose.

File API – Introduced methods for upload, download, copy, move, delete files : input documents and rendering results, in the cloud storage

Upload file to Storage

Download file from Storage

Folder API – Introduced methods for create, copy, move, delete folders in the cloud storage

Storage API – Introduced methods for getting storage information and file information

Comparison API

In this digital era, Document comparison is a basic requirement of individuals and organizations for their legal and financial tasks. And GroupDocs.Comparison Cloud REST API is a proven API for developers to add this feature in their applications without worrying about platform dependence. It can be used on any platform without any third party software. It provides simple methods to compare most popular business file formats (Word, Excel, PowerPoint, PDF, Images, Email, Html, Note). Following API methods

Comparisons – Compares source and target documents and returns a link to saved result

POST ​/comparison​/comparisons

Changes – Retrieves a list of changes between source and target documents

POST ​/comparison​/changes

Update – Accepts or rejects changes to the resultant document and returns a link to saved result

PUT ​/comparison​/updates

Here we will show you how easily you can compare two versions of the same document for changes with default Comparison options and get result document path.
