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);
auto notesOptions = opts->get_NotesCommentsLayouting();
notesOptions->set_NotesPosition(NotesPositions::BottomFull);
// 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);

The following example shows how to convert PowerPoint to TIFF with custom image pixel format.

// Instantiate a Presentation object that represents a Presentation file
auto presentation = System::MakeObject<Presentation>(u"DemoFile.pptx");

System::SharedPtr<TiffOptions> options = System::MakeObject<TiffOptions>();
options->set_PixelFormat(ImagePixelFormat::Format8bppIndexed);

// Save the presentation to TIFF with specified image size
presentation->Save(u"Tiff_With_Custom_Image_Pixel_Format_out.tiff", SaveFormat::Tiff, options);
