This is a professional solution to optimize and compress EPUB in C++. Use C++ to maximize EPUB optimization/compression speed. Try it online for free!
We currently do not accept DOCX files as input. But we can produce DOCX files as an ouput. We look forward to full DOCX support in the near future.
C++ library is a stand-alone solution and doesn't require any third party software installed.
Make DOCX files smaller without loss of quality. The C++ library provides developers with an integrated API to optimize DOCX content. DOCX optimization occurs by compressing images inside DOCX files, as well as by removing unused data.
Ebook lossless compression and content optimization made easy with 'Aspose.Words for C++'. The following example demonstrates how to optimize the content of a DOCX file in C++:
dotnet add package Aspose.Words.Cpp
using namespace Aspose::Words;
auto doc = MakeObject<Document>(u"Input.docx");
doc->Cleanup();
auto nodes = doc->GetChildNodes(NodeType::Shape, true);
for (const auto& shape : System::IterateOver<Shape>(nodes))
{
if (shape->get_HasImage())
{
// It's up to developer to choose the library for image compression.
auto image = System::Drawing::Image::Fromstream(shape->get_ImageData()->ToStream());
// ...
// Compress image and set it back to the shape.
shape->get_ImageData()->SetImage("yourCompressedImage");
}
}
doc->Save(u"Output.epub");
using namespace Aspose::Words;
auto doc = MakeObject<Document>(u"Input.docx");
doc->Cleanup();
auto nodes = doc->GetChildNodes(NodeType::Shape, true);
for (const auto& shape : System::IterateOver<Shape>(nodes))
{
if (shape->get_HasImage())
{
// It's up to developer to choose the library for image compression.
auto image =
System::Drawing::Image::FromStream(shape->get_ImageData()->ToStream());
// ...
// Compress image and set it back to the shape.
shape->get_ImageData()->SetImage("yourCompressedImage");
}
}
auto saveOptions = MakeObject<PdfSaveOptions>();
saveOptions->set_CacheBackgroundGraphics(true);
doc->Save(u"Output.epub", saveOptions);
using namespace Aspose::Words;
auto doc = MakeObject<Document>(u"Input.docx");
doc->Cleanup();
auto nodes = doc->GetChildNodes(NodeType::Shape, true);
for (const auto& shape : System::IterateOver<Shape>(nodes))
{
if (shape->get_HasImage())
{
// It's up to developer to choose the library for image compression.
auto image = System::Drawing::Image::Fromstream(shape->get_ImageData()->ToStream());
// ...
// Compress image and set it back to the shape.
shape->get_ImageData()->SetImage("yourCompressedImage");
}
}
doc->Save(u"Output.epub");
using namespace Aspose::Words;
auto doc = MakeObject<Document>(u"Input.docx");
doc->Cleanup();
auto nodes = doc->GetChildNodes(NodeType::Shape, true);
for (const auto& shape : System::IterateOver<Shape>(nodes))
{
if (shape->get_HasImage())
{
// It's up to developer to choose the library for image compression.
auto image =
System::Drawing::Image::FromStream(shape->get_ImageData()->ToStream());
// ...
// Compress image and set it back to the shape.
shape->get_ImageData()->SetImage("yourCompressedImage");
}
}
auto saveOptions = MakeObject<OoxmlSaveOptions>();
saveOptions->set_CompressionLevel(CompressionLevel::Maximum);
doc->Save(u"Output.epub", saveOptions);
using namespace Aspose::Words;
auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);
auto shape = builder->InsertImage(u"Input.docx");
auto saveOptions = MakeObject<ImageSaveOptions>(SaveFormat::Docx);
shape->GetShapeRenderer()->Save(u"Output.epub", saveOptions);
There are three options to install Aspose.Words for C++ to your developer environment. Please choose one that resembles your needs and follow the step-by-step instructions:
You can use this C++ library to develop software on Microsoft Windows, Linux and macOS operating systems:
If you develop software for Linux or macOS, please check information on additional library dependencies (fontconfig and mesa-glu open-source packages) in Product Documentation.
You can optimize files in many other file formats:
