Combine image using C++ REST API

Easily merge image files together in C++ code. This C++ library is designed to combine multiple image files into a single file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native image merging solution that provides C++ programmers with both great development flexibility and powerful features. Joining image files together is often used when it is necessary to create a set of documents of the same structure, each of which contains unique data. By merging image files, you can automate your digital workflows and offload some routine parts of the process to fast and efficient image processing C++ software.

Merge multiple image into one in C++

You may need to combine image files together in many cases. For example, you may want to combine multiple image files together before printing or archiving.

image merging can be part of a whole integrated document-processing approach for generating documents from disparate data sources. Such tasks involve the use of a full-featured image manipulation C++ library that will process a set of image files and merge them together in the shortest possible time, producing a compact and accurate result.

Merge image files in C++

To merge image in C++, you need at least two source image files. For a quick start, please check out the C++ code example below.

How to merge image C++ REST API

  1. Install C++ SDK and add the reference (import the library) to your C++ project.
  2. Open the source image file in C++.
  3. Load a document to append from the Cloud storage.
  4. Call the appendDocumentOnline() method, passing the output filename with the required extension.
  5. Get the combined result as a single file.
