Examples

Shows how to use the FileFormatUtil methods to detect the format of a document.

# Load a document from a file that is missing a file extension, and then detect its file format.
with system_helper.io.File.open_read(MY_DIR + 'Word document with missing file extension') as doc_stream:
    info = aw.FileFormatUtil.detect_file_format(stream=doc_stream)
    load_format = info.load_format
    self.assertEqual(aw.LoadFormat.DOC, load_format)
    # Below are two methods of converting a LoadFormat to its corresponding SaveFormat.
    # 1 -  Get the file extension string for the LoadFormat, then get the corresponding SaveFormat from that string:
    file_extension = aw.FileFormatUtil.load_format_to_extension(load_format)
    save_format = aw.FileFormatUtil.extension_to_save_format(file_extension)
    # 2 -  Convert the LoadFormat directly to its SaveFormat:
    save_format = aw.FileFormatUtil.load_format_to_save_format(load_format)
    # Load a document from the stream, and then save it to the automatically detected file extension.
    doc = aw.Document(stream=doc_stream)
    self.assertEqual('.doc', aw.FileFormatUtil.save_format_to_extension(save_format))
    doc.save(file_name=ARTIFACTS_DIR + 'File.SaveToDetectedFileFormat' + aw.FileFormatUtil.save_format_to_extension(save_format))
