Easily merge PDF documents and export the result to PNG graphic format in JavaScript code. This JavaScript library is designed to combine multiple PDF files into a single PNG image using the REST API, i.e. by passing HTTPS calls over the Internet.
This is a professional Cloud-native PDF to PNG merging solution that provides JavaScript programmers with both great development flexibility and powerful features. By merging documents, you can automate your digital PDF/PNG workflows and offload some routine parts of the process to fast and efficient PDF processing JavaScript software.
You may need to combine PDF files into a single PNG image in many cases. For example, you may want to combine multiple PDF files together before printing or archiving.
PDF merging can be part of a whole integrated document-processing approach for generating PNG images from disparate data sources. Such tasks involve the use of a full-featured PDF/PNG manipulation JavaScript library that will process a set of PDF files and merge them together in the shortest possible time, producing a compact and accurate graphical output.
To perform PDF to PNG merging in JavaScript, you need at least two source PDF documents. For a quick start, please check out the JavaScript code example below.
import * as fs from "fs";
const wordsApi = new WordsApi("####-####-####-####-####", "##################");
const document = fs.createReadStream("Input1.pdf");
const mergeProps = new model.DocumentEntry({
fileReference: model.FileReference.fromRemoteFilePath("Input2.pdf"),
importFormatMode: "KeepSourceFormatting"
})
const documentEntries = [
mergeProps
]
const documentList = new model.DocumentEntryList({
documentEntries: documentEntries
})
const appendDocumentOnline = new model.AppendDocumentOnlineRequest({
document: document,
documentList: documentList
});
wordsApi.appendDocumentOnline(appendDocumentOnline)
.then((appendDocumentOnlineResult) => {
console.log("Result of AppendDocumentOnline: ", appendDocumentOnlineResult);
const splitDocumentOnline = new model.SplitDocumentOnlineRequest({
document: appendDocumentOnlineResult,
format: "png",
zipOutput: true
});
wordsApi.splitDocumentOnline(splitDocumentOnline)
.then((splitDocumentOnlineResult) => {
console.log("Result of SplitDocumentOnline: ", splitDocumentOnlineResult);
});
