Combine PNG to PNG using Dart REST API

Easily merge PNG to PNG format in Dart code. This Dart 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 Dart 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 Dart software.

Merge several PNG into one PNG in Dart

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 Dart 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 Dart

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

final config = Configuration("####-####-####-####-####", "##################");
final wordsApi = WordsApi(config);

final document = (await File(
   'Input1.png').readAsBytes()).buffer.asByteData();
final mergeProps = ImageEntry();
mergeProps.fileReference = FileReference.fromRemoteFile('Input2.png');
final imageEntries = [
  mergeProps];
final imageList = ImageEntryList();
imageList.imageEntries = imageEntries;
final appendDocumentOnline = AppendDocumentOnlineRequest(document, imageList);
final mergedImages = await wordsApi.appendDocumentOnline(appendDocumentOnline);

final convertDocument = ConvertDocumentRequest(mergedImages, 'png');
await wordsApi.convertDocument(convertDocument);
