Public API changes

Converter class

  1. The Converter class constructor that accepts a stream has been removed and replaced with a stream supplier:
const fs = require('fs');
const java = require('java');
const path = require('path');

// Create read stream from file
const readStream = fs.createReadStream("source.docx");

// Convert to GroupDocs input stream
const stream = await groupdocs.readDataFromStream(readStream);

// Create Supplier<InputStream> that returns the stream (equivalent to Java lambda: () -> stream)
const streamSupplier = java.newProxy('java.util.function.Supplier', {
  get: function() {
    return stream;
  }
});

// Initialize converter with stream data
const converter = new groupdocs.Converter(streamSupplier);

PdfConvertOptions class

  1. Method setWidth renamed to setPageWidth
  2. Method setHeight renamed to setPageHeight
// Configure PDF conversion options with advanced settings
const convertOptions = new groupdocs.PdfConvertOptions();
convertOptions.setPageWidth(1024); // Set output width
convertOptions.setPageHeight(768); // Set output height

How to get the update
