TIFF 6.0 Specification
Final—June 3, 1992
Section 8: Baseline Field Reference Guide
This section contains detailed information about all the Baseline fields defined in
this version of TIFF. A
Baseline field
is any field commonly found in a Baseline
TIFF file, whether required or not.
For convenience, fields that were defined in earlier versions of the TIFF specifica-
tion but are no longer generally recommended have also been included in this
section.
New fields that are associated with optional features are not listed in this section.
See Part 2 for descriptions of these new fields. There is a complete list of all fields
described in this specification in Appendix A, and there are entries for all TIFF
fields in the index.
More fields may be added in future versions. Whenever possible they will be
added in a way that allows old TIFF readers to read newer TIFF files.
The documentation for each field contains:
• the name of the field
• the Tag number
•
•
•
•
the field Type
the required Number of Values (N); i.e., the Count
comments describing the field
the default, if any
If the field does not exist, readers must assume the default value for the field.
Most of the fields described in this part of the document are not required or are
required only for particular types of TIFF files. See the preceding sections for lists
of required fields.
Before defining the fields, you must understand these basic concepts: A Baseline
TIFF
image
is defined to be a two-dimensional array of
pixels,
each of which
consists of one or more color
components.
Monochromatic data has one color
component per pixel, while RGB color data has three color components per pixel.
The Fields
Artist
Person who created the image.
Tag
= 315 (13B.H)
Type = ASCII
Note: some older TIFF files used this tag for storing Copyright information.
