29
* Library Configuration Definitions.
31
* This file defines the default configuration for the library.
32
* If the target system does not have make or a way to specify
33
* #defines on the command line, this file can be edited to
34
* configure the library. Otherwise, one can override portability
35
* and configuration-related definitions from a Makefile or command
36
* line by defining COMPRESSION_SUPPORT (see below).
40
* General portability-related defines:
42
* HAVE_IEEEFP define as 0 or 1 according to the floating point
43
* format suported by the machine
44
* BSDTYPES define this if your system does NOT define the
45
* usual 4BSD typedefs u_int et. al.
46
* HAVE_MMAP enable support for memory mapping read-only files;
47
* this is typically deduced by the configure script
48
* HOST_FILLORDER native cpu bit order: one of FILLORDER_MSB2LSB
49
* or FILLODER_LSB2MSB; this is typically set by the
51
* HOST_BIGENDIAN native cpu byte order: 1 if big-endian (Motorola)
52
* or 0 if little-endian (Intel); this may be used
53
* in codecs to optimize code
54
* USE_64BIT_API set to 1 if tif_unix.c should use lseek64(),
55
* fstat64() and stat64 allowing 2-4GB files.

* Compression support defines:
75
* CCITT_SUPPORT enable support for CCITT Group 3 & 4 algorithms
76
* PACKBITS_SUPPORT enable support for Macintosh PackBits algorithm
77
* LZW_SUPPORT enable support for LZW algorithm
78
* THUNDER_SUPPORT enable support for ThunderScan 4-bit RLE algorithm
79
* NEXT_SUPPORT enable support for NeXT 2-bit RLE algorithm
80
* OJPEG_SUPPORT enable support for 6.0-style JPEG DCT algorithms
81
* (requires IJG software)
82
* JPEG_SUPPORT enable support for post-6.0-style JPEG DCT algorithms
83
* (requires freely available IJG software, see tif_jpeg.c)
84
* ZIP_SUPPORT enable support for Deflate algorithm
85
* (requires freely available zlib software, see tif_zip.c)

* PIXARLOG_SUPPORT enable support for Pixar log-format algorithm
87
* LOGLUV_SUPPORT enable support for LogLuv high dynamic range encoding

113
* STRIPCHOP_DEFAULT default handling of strip chopping support (whether
114
* or not to convert single-strip uncompressed images
115
* to mutiple strips of ~8Kb--to reduce memory use)
116
* SUBIFD_SUPPORT enable support for SubIFD tag (thumbnails and such)
117
* DEFAULT_EXTRASAMPLE_AS_ALPHA
118
* The RGBA interface will treat a fourth sample with
119
* no EXTRASAMPLE_ value as being ASSOCALPHA. Many
120
* packages produce RGBA files but don't mark the alpha
122
* CHECK_JPEG_YCBCR_SUBSAMPLING
123
* Enable picking up YCbCr subsampling info from the
124
* JPEG data stream to support files lacking the tag.
125
