Aspose::Words::Saving::ImageSavingArgs::get_KeepImageStreamOpen method

ImageSavingArgs::get_KeepImageStreamOpen method

Specifies whether Aspose.Words should keep the stream open or close it after saving an image.

bool Aspose::Words::Saving::ImageSavingArgs::get_KeepImageStreamOpen() const

Remarks

Default is false and Aspose.Words will close the stream you provided in the ImageStream property after writing an image into it. Specify true to keep the stream open.

Examples

Shows how to involve an image saving callback in an HTML conversion process.

void ImageSavingCallback()
{
    auto doc = MakeObject<Document>(MyDir + u"Rendering.docx");

    // When we save the document to HTML, we can pass a SaveOptions object to designate a callback
    // to customize the image saving process.
    auto options = MakeObject<HtmlSaveOptions>();
    options->set_ImageSavingCallback(MakeObject<ExHtmlSaveOptions::ImageShapePrinter>());

    doc->Save(ArtifactsDir + u"HtmlSaveOptions.ImageSavingCallback.html", options);
}

class ImageShapePrinter : public IImageSavingCallback
{
public:
    ImageShapePrinter() : mImageCount(0)
    {
    }

private:
    int mImageCount;

    void ImageSaving(SharedPtr<ImageSavingArgs> args) override
    {
        args->set_KeepImageStreamOpen(false);
        ASSERT_TRUE(args->get_IsImageAvailable());

        std::cout << args->get_Document()->get_OriginalFileName().Split(MakeArray<char16_t>({u'\\'}))->LINQ_Last() << " Image #" << ++mImageCount
                  << std::endl;

        auto layoutCollector = MakeObject<LayoutCollector>(args->get_Document());

        std::cout << "\tOn page:\t" << layoutCollector->GetStartPageIndex(args->get_CurrentShape()) << std::endl;
        std::cout << "\tDimensions:\t" << args->get_CurrentShape()->get_Bounds() << std::endl;
        std::cout << String::Format(u"\tAlignment:\t{0}", args->get_CurrentShape()->get_VerticalAlignment()) << std::endl;
        std::cout << String::Format(u"\tWrap type:\t{0}", args->get_CurrentShape()->get_WrapType()) << std::endl;
        std::cout << "Output filename:\t" << args->get_ImageFileName() << "\n" << std::endl;
    }
};
