10139N/A<para><filename>&cmd;</filename> is a library for reading and writing data
10139N/Afiles encoded with the Tag Image File format, Revision 4.0 or later. The TIFF
10139N/Afile format is suitable for archiving multicolor and monochromatic image data.

10139N/A<para>The <filename>&cmd;</filename> library supports several compression
10139N/Aalgorithms, as indicated by the Compression field, including:</para>
10139N/A<itemizedlist>

10139N/A<para>In addition, several nonstandard compression algorithms are supported:

10139N/A<listitem><para>4-bit compression algorithm used by the ThunderScan program

10139N/A</itemizedlist>
10139N/A<para>Directory information may be in either little- or big-endian byte order.
10139N/AByte swapping is automatically done by the library.</para>
10139N/A<para>Data bit ordering may be either Most Significant Bit (MSB) to Least
10139N/ASignificant Bit (LSB), or LSB to MSB.</para>
10139N/A<para>The library does not support files in which the BitsPerSample, Compression,
10139N/AMinSampleValue, or MaxSampleValue fields are defined differently on a per-sample
10139N/Abasis. In Revision 6.0, the Compression tag is not defined on a per-sample
10139N/Abasis, so this is immaterial.</para>

10139N/A<title>Data Types</title>
10139N/A<para>The <filename>&cmd;</filename> library makes extensive use of C typedefs
10139N/Ato promote portability. Two sets of typedefs are used, one for communication
10139N/Awith clients of the library and one for internal data structures and parsing
10139N/Aof the TIFF format. The following typedefs are exposed to users either through
10139N/Afunction definitions or through parameters passed through the <literal>varargs
10139N/A</literal> interfaces.</para>
10139N/A<itemizedlist>
10139N/A<listitem><para><literal>typedef unsigned short uint16;</literal> &mdash;

10139N/A<para><literal>tstrip_t</literal>, <literal>ttile_t</literal>, and <literal>
10139N/Atsize_t</literal> are limited to 32-bit quantities because they are stored
10139N/Ain 32-bit fields in the TIFF image. Similarly, <literal>tsample_t</literal>
10139N/Ais limited by the 16-bit field used to store the <literal>SamplesPerPixel
10139N/A</literal> tag. <literal>tdir_t</literal> constrains the maximum number of
10139N/AIFDs that may appear in an image and may be an arbitrary size without penalty.
10139N/A</para>
10139N/A<para><literal>ttag_t</literal> must be <literal>int</literal>, <literal>
10139N/Aunsigned int</literal>, <literal>pointer</literal>, or <literal>double</literal>
10139N/Abecause the library uses a <literal>varargs</literal> interface and ANSI C
10139N/Arestricts the type of the parameter before an ellipsis to be a promoted type.
10139N/A</para>
10139N/A<para><literal>toff_t</literal> is defined as <literal>int32</literal> because
10139N/ATIFF file offsets are unsigned 32-bit quantities. A signed value is used because
10139N/Asome interfaces return -1 on error.</para>
10139N/A<para>User-specified data references are passed as opaque handles and only
10139N/Acast at the lowest layers where their type is presumed.</para>
