<title>Validation rules for the TIFF Image File Directory Entry(IFD)</title>
<description>Each 12-byte IFD entry has the following format:
Bytes 0-1 The Tag that identifies the field.
Bytes 2-3 The field Type.
Bytes 4-7 The number of values, Count of the indicated Type.
Bytes 8-11 The Value Offset, the file offset (in bytes) of the Value for the field.
The Value is expected to begin on a word boundary; the corresponding Value Offset will thus be an even number.
This file offset may point anywhere in the file, even after the image data.</description>
<rule id="IFDE-0001-1" context="ifd" level="error" experimental="true">
<title>invalid IFDE type</title>
<description>The field types and their sizes are:
1 = BYTE 8-bit unsigned integer.
2 = ASCII 8-bit byte that contains a 7-bit ASCII code; the last byte must be NUL (binary zero).
3 = SHORT 16-bit (2-byte) unsigned integer.
4 = LONG 32-bit (4-byte) unsigned integer.
5 = RATIONAL Two LONGs: the first represents the numerator of a fraction; the second, the denominator.
7 = UNDEFINED An 8-bit byte that may contain anything, depending on the definition of the field.
To store a complicated data structure in a private tag, use the UNDEFINED field type and set the Count to the number of bytes required to hold the data structure.</description>

Currently defined values are:
0 = BackgroundColor. Recommended for MP, BP, and BL images
1 = ImageColor (foreground colour). for MP, BP, and BL images
2 = RGB. In the RGB model, a color is described as a combination of the three primary colors of light (red, green, and blue) in particular concentrations.
5 = CMYK. (The primary colour space for TIFF/IT Standard) for CT, LW, SD, and HC images, file data in the sequence CMYK, or separated image file data in other colours or sequences if modified by other fields.
6 = YCbCr.
8 = CIE L*a*b*.

0 = WhiteIsZero. For bilevel and grayscale images: 0 is imaged as white.
1 = BlackIsZero. For bilevel and grayscale images: 0 is imaged as black.
2 = RGB. RGB value of (0,0,0) represents black, and (255,255,255) represents white, assuming 8-bit components. The components are stored in the indicated order: first Red, then Green, then Blue.
3 = Palette color. In this model, a color is described with a single component. The value of the component is used as an index into the red, green and blue curves in the ColorMap field to retrieve an RGB triplet that defines the color. When PhotometricInterpretation=3 is used, ColorMap must be present and SamplesPerPixel must be 1.
4 = Transparency Mask. This means that the image is used to define an irregularly shaped region of another image in the same TIFF file. SamplesPerPixel and BitsPerSample must be 1. PackBits compression is recommended. The 1-bits define the interior of the region; the 0-bits define the exterior of the region.

If a DotRange pair is included for each component, the values for each component are stored together, so that the pair for Cyan would be first, followed by the pair for Magenta, and so on.
Use of multiple dot ranges is, however, strongly discouraged in the interests of simplicity and compatibility with ANSI IT8 standards.
A number of prepress systems like to keep some “headroom” and “footroom” on both ends of the range. What to do with components that are less than the 0% aim point or greater than the 100% aim point is not specified and is application-dependent.
It is strongly recommended that a CMYK TIFF writer not attempt to use this field to reverse the sense of the pixel values so that smaller values mean more ink instead of less ink. That is, DotRange[0] should be less than DotRange[1].
DotRange[0] and DotRange[1] must be within the range [0, (2**BitsPerSample) - 1].
Tag = 336 (150.H)
Type = BYTE or SHORT

Default: a component value of 0 corresponds to a 0% dot, and a component value of 255 (assuming 8-bit pixels) corresponds to a 100% dot. That is, DotRange[0] = 0 and DotRange[1] = (2**BitsPerSample) - 1.

<title>TransferFunction</title>
<description>Describes a transfer function for the image in tabular style. Pixel components can be gamma-compensated, companded, non-uniformly quantized, or coded in some other way. The TransferFunction maps the pixel components from a non-linear
BitsPerSample (e.g. 8-bit) form into a 16-bit linear form without a perceptible loss of accuracy.
If N = 1 << BitsPerSample, the transfer function is the same for each channel and all channels share a single table. Of course, this assumes that each channel has the same BitsPerSample value.
If N = 3 * (1 << BitsPerSample), there are three tables, and the ordering is the same as it is for pixel components of the PhotometricInterpretation field. These tables are separate and not interleaved. For example, with RGB images all red entries come first, followed by all green entries, followed by all blue entries.

<title>TIFF/IT-CT Colour continuous-tone picture</title>
<description>There are three formats for describing the pixel structure of colour continuous-tone picture file data:
pixel interleaving (also called chunky format).
line interleaving (also called row interleaving).
colour interleaving (also called planar format).
TIFF/IT-CT makes use of all the features and functionality supported by the TIFF and TIFF/IT fields
appropriate to colour continuous-tone picture images.
TIFF/IT-CT for RGB (PhotometricInterpretation value of 2) and LAB (PhotometricInterpretation value of 8) can
be considered as an expansion of TIFF/IT-CT (see Annex G and Annex H, respectively).
TIFF/IT-CT permit optional JPEG or Flate compression of image data.
NOTE Some machines and applications require data to be written to 16-bit word boundaries. Therefore, if the
number of bytes per line is odd, there would be one fill byte at the end of each line. In this case, field 34019
(RasterPadding) with value 1 indicates the value of the padding to the word boundary (word-aligned), and value 32895 for
field 259 (Compression) indicates the presence of such padding.

one or more blocks of run-length encoded data describing the colour line-art image in terms of colour numbers
and run lengths.The second part is a colour table (in the IFD) that defines the colour values for the colour
numbers of the first part.The third part is a table describing the separations of the second part.This data
structure is similar to binary line-art data with the addition of two colour tables for colour specification.
TIFF/IT-LW makes use of all the features and functionality supported by the TIFF and TIFF/IT fields

NOTE TIFF/IT-LW files are not readable by typical TIFF 6.0 readers and cannot be written by typical TIFF 6.0 writers
because of the mandatory use of TIFF/IT-specific fields and values and non-traditional interpretations of other TIFF 6.0
fields and values (e.g. compression by mandatory run length encoding).

<title>High-resolution continuous-tone (HC) file</title>
<description>High-resolution continuous-tone data consist of an image file of one or more blocks of run-length encoded
pixel data. The number of lines is defined in the ImageLength field. Each line is made up of pixel runs and
starts and ends with a blank pixel run (all zero bytes). Each pixel run is made up of two components: a run
length followed by a colour value. The run length is a 16-bit integer as defined in 7.4.2.4.2. The big-endian
byte order is used regardless of the order used in the TIFF/IT directories (IFD). The sum of the run lengths in
the line shall be the value found in ImageWidth. Run lengths shall not cross line boundaries. The colour value
is defined by the values of SamplesPerPixel, BitsPerSample, ColorSequence and DotRange in the same
manner that CT colour values are specified, except that a special case of colour value is reserved for a
transparent colour, if used.
TIFF/IT field 34028 is used as the transparency indicator. If transparency is used, colour values of zero
become a special case, and signify transparency in that separation of the high-resolution continuous-tone
(HC) data. Transparency indicates that the underlying colour picture separation value is used.
TIFF/IT-HC makes use of all the features and functionality supported by the TIFF and TIFF/IT fields
appropriate to high-resolution continuous-tone images.
NOTE TIFF/IT-HC is not readable by typical TIFF 6.0 readers and cannot
be written by typical TIFF 6.0 writers because of the mandatory use of TIFF/IT-specific fields and values and nontraditional
interpretations of other TIFF 6.0 fields and values (e.g. compression by mandatory run-length encoding).

<title>Screened data image (SD) file</title>
<description>The pixel structure of screened data image files is described by colour interleaving (also called planar format).
All lines of one colour (separation) are followed by all lines of the next colour. The order of planes of colour is
defined by PhotometricInterpretation or ColorSequence.
The data stream indicates whether or not a dot is intended to be imaged at a particular position. The bits in the
data stream function as a switch between imaged and unimaged points. Bitmap fill order is from most
significant bit to least significant bit within the byte, the default TIFF 6.0 fill order.
TIFF/IT-SD makes use of all the features and functionality supported by the TIFF and TIFF/IT fields
appropriate to prescreened (copydot) colour separation images.
NOTE TIFF/IT-SD files are not readable by typical TIFF 6.0 readers and neither can be
written by TIFF 6.0 writers because of the non-traditional interpretations of some TIFF 6.0 fields and values (e.g., the
combination of PhotometricInterpretation and BitsPerSample). It is possible to write filters for DTP applications that need
to read and write TIFF/IT-SD files.

<title>Final page (FP) file</title>
<description>Typically, a final page, ready for exposure on an output recorder, consists of more than one of the CT, MP, SD,
LW, BL, BP and HC raster formats described in this International Standard. TIFF/IT-FP provides a mechanism
for associating image files of the different types that make up a final page.
By default, it is assumed that, for each image type, the page assembly processes have combined all the pageinput
components of that data type into one output file: the single-component image file of that data type for
the page, though this is a requirement only for both TIFF/IT-P1 and TIFF/IT-P2 conformance.
The component-image files of a final page may be of any one of the TIFF/IT, TIFF/IT-P1, or TIFF/IT-P2
conformance levels. The final page is considered to be TIFF/IT-P1-conformant only if all of its component files
are TIFF/IT-P1-conformant and its own fields are TIFF/IT-FP/P1-conformant as specified in 7.10.2.5. The final
page is considered to be TIFF/IT-P2-conformant only if all of its component files are TIFF/IT-P1- or
TIFF/IT-P2-conformant and its own fields are TIFF/IT-FP/P2-conformant as specified in 7.10.2.5.</description>
