Unpack MHT to Files

See more MHT / HTML Email Examples

Demonstrates how to unpack a .mhtml to files. Unpacks the HTML and to a directory, and image files to a sub-directory located under the directory where the HTML file is unpacked. The image links in the HTML are updated to point to the image files. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final mht = CkMht();

  // This should be an absolute or relative path to the MHT file.
  // It is the MHT to be unpacked.
  final mhtPath = 'qa_data/mht/test.mht';

  final unpackDir = 'C:/AAWorkarea/mht_unpack';
  final htmlFilename = 'test.html';
  final partsSubDir = 'images';

  // Unpacking will create the HTML file C:/AAWorkarea/mht_unpack/test.html
  // The image files are unpacked to C:/AAWorkarea/mht_unpack/images
  // The unpackDir and partsSubDir are automatically created if needed.

  try {
    mht.unpackMHT(mhtPath, unpackDir, htmlFilename, partsSubDir);
    print('Success.');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    print('Failed.');
  }
