using (var writer = new TiffWriter(@"Images\Output\result.tif"))
{
// Load bitmap for the extra channel.
// Note: image for extra channel must be gray scale and have the same dimensions and DPI as the source one.
using (var extraBitmap = new Bitmap(@"Images\extraChannel.jpg"))
{
// Create extra channel options based on extraBitmap.
var extraChannel = new TiffExtraChannelEntry(extraBitmap, TiffChannelType.Alpha);
writer.ExtraChannels.Add(extraChannel);
Pipeline.Run(reader + writer);
