Aspose::Words::Drawing::Shape::get_HasImage method

Shape::get_HasImage method

Returns true if the shape has image bytes or links an image.

bool Aspose::Words::Drawing::Shape::get_HasImage()

Examples

Shows how to extract images from a document, and save them to the local file system as individual files.

auto doc = System::MakeObject<Aspose::Words::Document>(get_MyDir() + u"Images.docx");

// Get the collection of shapes from the document,
// and save the image data of every shape with an image as a file to the local file system.
System::SharedPtr<Aspose::Words::NodeCollection> shapes = doc->GetChildNodes(Aspose::Words::NodeType::Shape, true);

{
    return (System::ExplicitCast<Aspose::Words::Drawing::Shape>(s))->get_HasImage();
}))));

int32_t imageIndex = 0;
for (auto&& shape : System::IterateOver(shapes->LINQ_OfType<System::SharedPtr<Aspose::Words::Drawing::Shape> >()))
{
    if (shape->get_HasImage())
    {
        // The image data of shapes may contain images of many possible image formats.
        // We can determine a file extension for each image automatically, based on its format.
        System::String imageFileName = System::String::Format(u"File.ExtractImages.{0}{1}", imageIndex, Aspose::Words::FileFormatUtil::ImageTypeToExtension(shape->get_ImageData()->get_ImageType()));
        shape->get_ImageData()->Save(get_ArtifactsDir() + imageFileName);
