Aspose::Words::Saving::CssSavingArgs::get_IsExportNeeded method

CssSavingArgs::get_IsExportNeeded method

Allows to specify whether the CSS will be exported to file and embedded to HTML document. Default is true. When this property is false, the CSS information will not be saved to a CSS file and will not be embedded to HTML document.

bool Aspose::Words::Saving::CssSavingArgs::get_IsExportNeeded() const

Examples

Shows how to work with CSS stylesheets that an HTML conversion creates.

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

    // Create an "HtmlFixedSaveOptions" object, which we can pass to the document's "Save" method
    // to modify how we convert the document to HTML.
    auto options = MakeObject<HtmlSaveOptions>();

    // Set the "CssStylesheetType" property to "CssStyleSheetType.External" to
    // accompany a saved HTML document with an external CSS stylesheet file.
    options->set_CssStyleSheetType(CssStyleSheetType::External);

    // Below are two ways of specifying directories and filenames for output CSS stylesheets.
    // 1 -  Use the "CssStyleSheetFileName" property to assign a filename to our stylesheet:
    options->set_CssStyleSheetFileName(ArtifactsDir + u"SavingCallback.ExternalCssFilenames.css");

    // 2 -  Use a custom callback to name our stylesheet:
    options->set_CssSavingCallback(
        MakeObject<ExSavingCallback::CustomCssSavingCallback>(ArtifactsDir + u"SavingCallback.ExternalCssFilenames.css", true, false));

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

class CustomCssSavingCallback : public ICssSavingCallback
{
public:
    CustomCssSavingCallback(String cssDocFilename, bool isExportNeeded, bool keepCssStreamOpen) : mIsExportNeeded(false), mKeepCssStreamOpen(false)
    {
        mCssTextFileName = cssDocFilename;
        mIsExportNeeded = isExportNeeded;
        mKeepCssStreamOpen = keepCssStreamOpen;
    }

    void CssSaving(SharedPtr<CssSavingArgs> args) override
    {
        // We can access the entire source document via the "Document" property.
        ASSERT_TRUE(args->get_Document()->get_OriginalFileName().EndsWith(u"Rendering.docx"));

        args->set_CssStream(MakeObject<System::IO::FileStream>(mCssTextFileName, System::IO::FileMode::Create));
        args->set_IsExportNeeded(mIsExportNeeded);
        args->set_KeepCssStreamOpen(mKeepCssStreamOpen);

        ASSERT_TRUE(args->get_CssStream()->get_CanWrite());
    }

private:
    String mCssTextFileName;
    bool mIsExportNeeded;
    bool mKeepCssStreamOpen;
};
