Combine PNG to PNG using JavaScript REST API

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

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

Merge several PNG into one PNG in JavaScript

You may need to combine PNG files into a single PNG file in many cases. For example, you may want to combine multiple PNG files together before printing or archiving.

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

Merge PNG to PNG in JavaScript

To perform PNG to PNG merging in JavaScript, you need at least two source PNG files. For a quick start, please check out the JavaScript code example below.

Upload files you want to combine
Select the target format from the list
import * as fs from "fs";

// Current APIs is under development.
const wordsApi = new WordsApi("####-####-####-####-####", "##################");

const document = fs.createReadStream("Input1.png");
const mergeProps = new model.ImageEntry({
    fileReference: model.FileReference.fromRemoteFilePath("Input2.png")
})
const imageEntries = [
    mergeProps
]
const imageList = new model.ImageEntryList({
    imageEntries: imageEntries
})
const appendDocumentOnline = new model.AppendDocumentOnlineRequest({
    document: document,
    imageList: imageList
});

wordsApi.appendDocumentOnline(appendDocumentOnline)
.then((appendDocumentOnlineResult) => {
    console.log("Result of AppendDocumentOnline: ", appendDocumentOnlineResult);

    const convertDocument = new model.ConvertDocumentRequest({
        document: appendDocumentOnlineResult,
        format: "png"
    });

    wordsApi.convertDocument(convertDocument)
    .then((convertDocumentResult) => {
        console.log("Result of ConvertDocument: ", convertDocumentResult);
    });
});
