Package-Level Type Names (total 4)

	/* sort by: alphabet | popularity */
	 type CompressionType int (basic type)
		CompressionType describes the type of compression used in Options.

		As Types Of (total 5)
			const CCITTGroup3
			const CCITTGroup4
			const Deflate
			const LZW
			const Uncompressed

	 type FormatError string (basic type)
		A FormatError reports that the input is not a valid TIFF image.

		Methods (only one)
			( FormatError) Error() string
		Implements (at least one exported)
			 FormatError : error

	 type Options (struct)
		Options are the encoding parameters.

		Fields (total 2)
			Compression CompressionType
				Compression is the type of compression used.

			Predictor bool
				Predictor determines whether a differencing predictor is used;
				if true, instead of each pixel's color, the color difference to the
				preceding one is saved. This improves the compression for certain
				types of images and compressors. For example, it works well for
				photos with Deflate compression.

		As Inputs Of (at least one exported)
			func Encode(w io.Writer, m image.Image, opt *Options) error

	 type UnsupportedError string (basic type)
		An UnsupportedError reports that the input uses a valid but
		unimplemented feature.

		Methods (only one)
			( UnsupportedError) Error() string
		Implements (at least one exported)
			 UnsupportedError : error


Package-Level Functions (total 3)

	 func Decode(r io.Reader) (img image.Image, err error)
		Decode reads a TIFF image from r and returns it as an image.Image.
		The type of Image returned depends on the contents of the TIFF.

	 func DecodeConfig(r io.Reader) (image.Config, error)
		DecodeConfig returns the color model and dimensions of a TIFF image without
		decoding the entire image.

	 func Encode(w io.Writer, m image.Image, opt *Options) error
		Encode writes the image m to w. opt determines the options used for
		encoding, such as the compression type. If opt is nil, an uncompressed
		image is written.


Package-Level Constants (total 5)

	const CCITTGroup3 CompressionType = 3
		Constants for supported compression types.

	const CCITTGroup4 CompressionType = 4
		Constants for supported compression types.

	const Deflate CompressionType = 1
		Constants for supported compression types.

	const LZW CompressionType = 2
		Constants for supported compression types.

	const Uncompressed CompressionType = 0
		Constants for supported compression types.
