Working with Images

Aspose.Words allows users to work with images in a very flexible way. In this article, you can explore only some of the possibilities of working with images.

How to Extract Images from a Document

All images are stored inside Shape nodes in a Document. To extract all images or images having a specific type from the document, follow these steps:

• Use the GetChildNodes method to select all Shape nodes.
• Iterate through resulting node collections.
• Check the HasImage boolean property.
• Extract image data using the ImageData property.
• Save image data to a file.

The following code example shows how to extract images from a document and save them as files:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
// The path to the documents directories.
System::String inputDataDir = GetInputDataDir_WorkingWithImages();
System::String outputDataDir = GetOutputDataDir_WorkingWithImages();
System::SharedPtr<Document> doc = System::MakeObject<Document>(inputDataDir + u"Image.SampleImages.doc");

System::SharedPtr<NodeCollection> shapes = doc->GetChildNodes(NodeType::Shape, true);
int32_t imageIndex = 0;

for (System::SharedPtr<Shape> shape : System::IterateOver<System::SharedPtr<Shape>>(shapes))
{
    if (shape->get_HasImage())
    {
        System::String imageFileName = System::String::Format(u"Image.ExportImages.{0}.{1}", imageIndex, FileFormatUtil::ImageTypeToExtension(shape->get_ImageData()->get_ImageType()));
        System::String imagePath = outputDataDir + imageFileName;
        shape->get_ImageData()->Save(imagePath);
        std::cout << "Image saved at " << imagePath.ToUtf8String() << std::endl;
        imageIndex++;
    }
}

Saving Images as WMF

Aspose.Words provides functionality to save all the available images in a document to WMF format while converting DOCX to RTF.

The following code example shows how to save images as WMF with RTF save options:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>(inputDataDir + u"TestFile.doc");

System::SharedPtr<RtfSaveOptions> options = System::MakeObject<RtfSaveOptions>();
options->set_SaveImagesAsWmf(true);

doc->Save(outputDataDir + u"WorkingWithRtfSaveOptions.SavingImagesAsWmf.rtf", options);
