| virtual bool FastCast(const Details::FastRttiBase&, void **) const | For internal purposes only. |
| BlackWhiteConversionMode get_BwConversionMode() override | Specifies the algorithm for converting a color image into a black and white image.

Remarks
The following example shows how to convert PowerPoint to TIFF with default size.
// Instantiate a Presentation object that represents a presentation file
auto presentation = System::MakeObject<Presentation>(u"DemoFile.pptx");
// Saving the presentation to TIFF document
presentation->Save(u"Tiffoutput_out.tiff", SaveFormat::Tiff);
The following example shows how to convert PowerPoint to TIFF with custom size.
// Instantiate a Presentation object that represents a Presentation file
auto pres = System::MakeObject<Presentation>(u"Convert_Tiff_Custom.pptx");
// Instantiate the TiffOptions class
System::SharedPtr<TiffOptions> opts = System::MakeObject<TiffOptions>();
// Setting compression type
opts->set_CompressionType(TiffCompressionTypes::Default);
System::SharedPtr<NotesCommentsLayoutingOptions> slidesLayoutOptions = System::MakeObject<NotesCommentsLayoutingOptions>();
slidesLayoutOptions->set_NotesPosition(NotesPositions::BottomFull);
opts->set_SlidesLayoutOptions(slidesLayoutOptions);
// Compression Types
// Default - Specifies the default compression scheme (LZW).
// None - Specifies no compression.
// CCITT3
// CCITT4
// LZW
// RLE
// Depth depends on the compression type and cannot be set manually.
// Resolution unit is always equal to "2" (dots per inch)
// Setting image DPI
opts->set_DpiX(200);
opts->set_DpiY(100);
// Set Image Size
opts->set_ImageSize(System::Drawing::Size(1728, 1078));
// Save the presentation to TIFF with specified image size
pres->Save(u"TiffWithCustomSize_out.tiff", SaveFormat::Tiff, opts);
