void dng_image_writer::WriteTIFF	(	dng_host &	host,
		dng_stream &	stream,
		const dng_image &	image,
		uint32	photometricInterpretation = piBlackIsZero,
		uint32	compression = ccUncompressed,

Write a dng_image to a dng_stream in TIFF format.

Parameters:

	host	Host interface used for progress updates, abort testing, buffer allocation, etc.
	stream	The dng_stream on which to write the TIFF.
	image	The actual image data to be written.
	photometricInterpretation	Either piBlackIsZero for monochrome or piRGB for RGB images.
	compression	Must be ccUncompressed .
	negative	If non-NULL, EXIF, IPTC, and XMP metadata from this negative is written to TIFF.
	space	If non-null and color space has an ICC profile, TIFF will be tagged with this profile. No color space conversion of image data occurs.
	resolution	If non-NULL, TIFF will be tagged with this resolution.
	thumbnail	If non-NULL, will be stored in TIFF as preview image.
	imageResources	If non-NULL, will image resources be stored in TIFF as well.

Write a dng_image to a dng_stream in DNG format.

Parameters:

	host	Host interface used for progress updates, abort testing, buffer allocation, etc.
	stream	The dng_stream on which to write the TIFF.
	negative	The image data and metadata (EXIF, IPTC, XMP) to be written.
	thumbnail	Thumbanil image. Must be provided.
	compression	Either ccUncompressed or ccJPEG for lossless JPEG.
	previewCount	The number of previews (not counting thumbnail).
	preview	Array of previewCount dng_preview pointers.
