Examples

The following example shows how to convert PowerPoint to TIFF with default size.

[C#]
// Instantiate a Presentation object that represents a presentation file
using (Presentation presentation = new Presentation("DemoFile.pptx"))
{
    // Saving the presentation to TIFF document
    presentation.Save("Tiffoutput_out.tiff", SaveFormat.Tiff);
}

The following example shows how to convert PowerPoint to TIFF with custom size.

[C#]
// Instantiate a Presentation object that represents a Presentation file
using (Presentation pres = new Presentation("Convert_Tiff_Custom.pptx"))
{
    // Instantiate the TiffOptions class
    TiffOptions opts = new TiffOptions();
    // Setting compression type
    opts.CompressionType = TiffCompressionTypes.Default;
    INotesCommentsLayoutingOptions notesOptions = opts.NotesCommentsLayouting;
    notesOptions.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.DpiX = 200;
    opts.DpiY = 100;
    // Set Image Size
    opts.ImageSize = new Size(1728, 1078);
    // Save the presentation to TIFF with specified image size
    pres.Save("TiffWithCustomSize_out.tiff", SaveFormat.Tiff, opts);
}

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

[C#]
// Instantiate a Presentation object that represents a Presentation file
using (Presentation presentation = new Presentation("DemoFile.pptx"))
{
    TiffOptions options = new TiffOptions();
    options.PixelFormat = ImagePixelFormat.Format8bppIndexed;
    /*
    ImagePixelFormat contains the following values (as could be seen from documentation):
    Format1bppIndexed; // 1 bits per pixel, indexed.
    Format4bppIndexed; // 4 bits per pixel, indexed.
    Format8bppIndexed; // 8 bits per pixel, indexed.
    Format24bppRgb; // 24 bits per pixel, RGB.
    Format32bppArgb; // 32 bits per pixel, ARGB.
    */
    // Save the presentation to TIFF with specified image size
    presentation.Save("Tiff_With_Custom_Image_Pixel_Format_out.tiff", SaveFormat.Tiff, options);
}
