Aspose::Words::Saving::CompressionLevel enum

CompressionLevel enum

Compression level for OOXML files. (DOCX and DOTX files are internally a ZIP-archive, this property controls the compression level of the archive. Note, that FlatOpc file is not a ZIP-archive, therefore, this property does not affect the FlatOpc files.)

enum class CompressionLevel

Values

Name	Value	Description
Normal	0	Normal compression level. Default compression level used by Aspose.Words.
Maximum	1	Maximum compression level.
Fast	2	Fast compression level.
SuperFast	3	Super Fast compression level. Microsoft Word uses this compression level.

Examples

Shows how to specify the compression level to use while saving an OOXML document.

auto doc = MakeObject<Document>(MyDir + u"Big document.docx");

// When we save the document to an OOXML format, we can create an OoxmlSaveOptions object
// and then pass it to the document's saving method to modify how we save the document.
// Set the "CompressionLevel" property to "CompressionLevel.Maximum" to apply the strongest and slowest compression.
// Set the "CompressionLevel" property to "CompressionLevel.Normal" to apply
// the default compression that Aspose.Words uses while saving OOXML documents.
// Set the "CompressionLevel" property to "CompressionLevel.Fast" to apply a faster and weaker compression.
// Set the "CompressionLevel" property to "CompressionLevel.SuperFast" to apply
// the default compression that Microsoft Word uses.
auto saveOptions = MakeObject<OoxmlSaveOptions>(SaveFormat::Docx);
saveOptions->set_CompressionLevel(compressionLevel);

SharedPtr<System::Diagnostics::Stopwatch> st = System::Diagnostics::Stopwatch::StartNew();
doc->Save(ArtifactsDir + u"OoxmlSaveOptions.DocumentCompression.docx", saveOptions);
st->Stop();

auto fileInfo = MakeObject<System::IO::FileInfo>(ArtifactsDir + u"OoxmlSaveOptions.DocumentCompression.docx");

std::cout << String::Format(u"Saving operation done using the \"{0}\" compression level:", compressionLevel) << std::endl;
std::cout << "\tDuration:\t" << st->get_ElapsedMilliseconds() << " ms" << std::endl;
std::cout << "\tFile Size:\t" << fileInfo->get_Length() << " bytes" << std::endl;
