TIFF tags

The table below shows the types and values of tags that can be included in the TIFF directory. If included, other tags or unacceptable values are normally ignored, but might occasionally cause processing to stop.

Tag name (number)	Value
ImageWidth (256)	0 - 65535
ImageHeight (257)	0 - 65535
BitsPerSample (258)	1, 4, or 8
Compression (259)	1, 3, 4, or 6
PhotometricInterpretation (262)	0
FillOrder (266)	1
StripOffsets (273)	0 - 2**32 - 1
SamplesPerPixel (277)	1
RowsPerStrip (278)	1 - ImageLength
StripByteCounts (279)	One of the following: ImageWidth ImageLength / 8 ImageWidth ImageLength / 2 ImageWidth ImageLength size of compressed image in bytes
MinSampleValue (280)	0
MaxSampleValue (281)	2**BitsPerSample-1
XResolution (282)	50 - 1200
YResolution (283)	50 - 1200
T4Options (292)	0 or 1
ResolutionUnit (296)	2
JpegIfOffset (513)	Available value
JpegIfByteCount (514)	Size of compressed image in bytes
JpegRestartInterval (515)	Available value

Tag values must be entered in byte, ASCII, short, long, or rational data format.

If the value of the tag is a pointer to data that is stored outside the tag entry, that pointer must be at the back of the directory that contains the tag, pointing either to the subsequent directory or the data domain preceding the end of the data, not to the data domain of the subsequent page.
