Reorder pages

Introduction

GroupDocs.Viewer Cloud allows you to reorder the document pages. The order of the pages in the source document is never changed, instead, the API applies reordering to the resultant PDF document.

The following code snippet shows how to reorder pages.

API Usage

There are steps that usage of GroupDocs.Viewer Cloud consists of:

  1. Upload input document into cloud storage
  2. Render document or get document info
  3. Download rendered document from storage

Steps 1 and 3 are storage operations, please refer to this File API documentation for usage details.

Swagger UI lets you call this REST API directly from the browser.

SDKs

The API is completely independent of your operating system, database system or development language. We provide and support API SDKs in many development languages in order to make it even easier to integrate. You can see our available SDKs list here.
