Combine image using Java REST API

Easily merge image files together in Java code. This Java 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 Java 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 Java software.

Merge multiple image into one in Java

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 Java 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 Java

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

ApiClient apiClient = new ApiClient("####-####-####-####-####", "##################", null);
WordsApi wordsApi = new WordsApi(apiClient);

byte[] document = Files.readAllBytes(
   Paths.get("Input1.png").toAbsolutePath());
ImageEntry mergeProps = new ImageEntry();
mergeProps.setFileReference(new FileReference("Input2.png"));

ArrayList imageEntries = new ArrayList();
imageEntries.add(mergeProps);

ImageEntryList imageList = new ImageEntryList();
imageList.setDocumentEntries(imageEntries);

AppendDocumentOnlineRequest appendDocumentOnline = new AppendDocumentOnlineRequest(
   document, imageList, null, null, null, null, null, null);
AppendDocumentOnline mergedImages = wordsApi.appendDocumentOnline(appendDocumentOnline);

ConvertDocumentRequest convertDocument = new ConvertDocumentRequest(
   mergedImages, "png", null, null, null, null);
wordsApi.convertDocument(convertDocument);
