1 -Basic Installation 2 -================== 3 - 4 - These are generic installation instructions. 5 - 6 - The `configure' shell script attempts to guess correct values for 7 -various system-dependent variables used during compilation. It uses 8 -those values to create a `Makefile' in each directory of the package. 9 -It may also create one or more `.h' files containing system-dependent 10 -definitions. Finally, it creates a shell script `config.status' that 11 -you can run in the future to recreate the current configuration, a file 12 -`config.cache' that saves the results of its tests to speed up 13 -reconfiguring, and a file `config.log' containing compiler output 14 -(useful mainly for debugging `configure'). 15 - 16 - If you need to do unusual things to compile the package, please try 17 -to figure out how `configure' could check whether to do them, and mail 18 -diffs or instructions to the address given in the `README' so they can 19 -be considered for the next release. If at some point `config.cache' 20 -contains results you don't want to keep, you may remove or edit it. 21 - 22 - The file `configure.in' is used to create `configure' by a program 23 -called `autoconf'. You only need `configure.in' if you want to change 24 -it or regenerate `configure' using a newer version of `autoconf'. 25 - 26 -The simplest way to compile this package is: 27 - 28 - 1. `cd' to the directory containing the package's source code and type 29 - `./configure' to configure the package for your system. If you're 30 - using `csh' on an old version of System V, you might need to type 31 - `sh ./configure' instead to prevent `csh' from trying to execute 32 - `configure' itself. 33 - 34 - Running `configure' takes awhile. While running, it prints some 35 - messages telling which features it is checking for. 36 - 37 - 2. Type `make' to compile the package. 38 - 39 - 3. Optionally, type `make check' to run any self-tests that come with 40 - the package. 41 - 42 - 4. Type `make install' to install the programs and any data files and 43 - documentation. 44 - 45 - 5. You can remove the program binaries and object files from the 46 - source code directory by typing `make clean'. To also remove the 47 - files that `configure' created (so you can compile the package for 48 - a different kind of computer), type `make distclean'. There is 49 - also a `make maintainer-clean' target, but that is intended mainly 50 - for the package's developers. If you use it, you may have to get 51 - all sorts of other programs in order to regenerate files that came 52 - with the distribution. 53 - 54 -Compilers and Options 55 -===================== 56 - 57 - Some systems require unusual options for compilation or linking that 58 -the `configure' script does not know about. You can give `configure' 59 -initial values for variables by setting them in the environment. Using 60 -a Bourne-compatible shell, you can do that on the command line like 61 -this: 62 - CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure 63 - 64 -Or on systems that have the `env' program, you can do it like this: 65 - env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure 66 - 67 -Compiling For Multiple Architectures 68 -==================================== 69 - 70 - You can compile the package for more than one kind of computer at the 71 -same time, by placing the object files for each architecture in their 72 -own directory. To do this, you must use a version of `make' that 73 -supports the `VPATH' variable, such as GNU `make'. `cd' to the 74 -directory where you want the object files and executables to go and run 75 -the `configure' script. `configure' automatically checks for the 76 -source code in the directory that `configure' is in and in `..'. 77 - 78 - If you have to use a `make' that does not supports the `VPATH' 79 -variable, you have to compile the package for one architecture at a time 80 -in the source code directory. After you have installed the package for 81 -one architecture, use `make distclean' before reconfiguring for another 82 -architecture. 83 - 84 -Installation Names 85 -================== 86 - 87 - By default, `make install' will install the package's files in 88 -`/usr/local/bin', `/usr/local/man', etc. You can specify an 89 -installation prefix other than `/usr/local' by giving `configure' the 90 -option `--prefix=PATH'. 91 - 92 - You can specify separate installation prefixes for 93 -architecture-specific files and architecture-independent files. If you 94 -give `configure' the option `--exec-prefix=PATH', the package will use 95 -PATH as the prefix for installing programs and libraries. 96 -Documentation and other data files will still use the regular prefix. 97 - 98 - In addition, if you use an unusual directory layout you can give 99 -options like `--bindir=PATH' to specify different values for particular 100 -kinds of files. Run `configure --help' for a list of the directories 101 -you can set and what kinds of files go in them. 102 - 103 - If the package supports it, you can cause programs to be installed 104 -with an extra prefix or suffix on their names by giving `configure' the 105 -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. 106 - 107 -Optional Features 108 -================= 109 - 110 - Some packages pay attention to `--enable-FEATURE' options to 111 -`configure', where FEATURE indicates an optional part of the package. 112 -They may also pay attention to `--with-PACKAGE' options, where PACKAGE 113 -is something like `gnu-as' or `x' (for the X Window System). The 114 -`README' should mention any `--enable-' and `--with-' options that the 115 -package recognizes. 116 - 117 - For packages that use the X Window System, `configure' can usually 118 -find the X include and library files automatically, but if it doesn't, 119 -you can use the `configure' options `--x-includes=DIR' and 120 -`--x-libraries=DIR' to specify their locations. 121 - 122 -Specifying the System Type 123 -========================== 124 - 125 - There may be some features `configure' can not figure out 126 -automatically, but needs to determine by the type of host the package 127 -will run on. Usually `configure' can figure that out, but if it prints 128 -a message saying it can not guess the host type, give it the 129 -`--host=TYPE' option. TYPE can either be a short name for the system 130 -type, such as `sun4', or a canonical name with three fields: 131 - CPU-COMPANY-SYSTEM 132 - 133 -See the file `config.sub' for the possible values of each field. If 134 -`config.sub' isn't included in this package, then this package doesn't 135 -need to know the host type. 136 - 137 - If you are building compiler tools for cross-compiling, you can also 138 -use the `--target=TYPE' option to select the type of system they will 139 -produce code for and the `--build=TYPE' option to select the type of 140 -system on which you are compiling the package. 141 - 142 -Sharing Defaults 143 -================ 144 - 145 - If you want to set default values for `configure' scripts to share, 146 -you can create a site shell script called `config.site' that gives 147 -default values for variables like `CC', `cache_file', and `prefix'. 148 -`configure' looks for `PREFIX/share/config.site' if it exists, then 149 -`PREFIX/etc/config.site' if it exists. Or, you can set the 150 -`CONFIG_SITE' environment variable to the location of the site script. 151 -A warning: not all `configure' scripts look for a site script. 152 - 153 -Operation Controls 154 -================== 155 - 156 - `configure' recognizes the following options to control how it 157 -operates. 158 - 159 -`--cache-file=FILE' 160 - Use and save the results of the tests in FILE instead of 161 - `./config.cache'. Set FILE to `/dev/null' to disable caching, for 162 - debugging `configure'. 163 - 164 -`--help' 165 - Print a summary of the options to `configure', and exit. 166 - 167 -`--quiet' 168 -`--silent' 169 -`-q' 170 - Do not print messages saying which checks are being made. To 171 - suppress all normal output, redirect it to `/dev/null' (any error 172 - messages will still be shown). 173 - 174 -`--srcdir=DIR' 175 - Look for the package's source code in directory DIR. Usually 176 - `configure' can determine that directory automatically. 177 - 178 -`--version' 179 - Print the version of Autoconf used to generate the `configure' 180 - script, and exit. 181 - 182 -`configure' also accepts some other, not widely useful, options. 183 -

All colors within a 524 - * histogram cell will be mapped to the same colormap entry, namely the one 525 - * closest to the cell's center. This may not be quite the closest entry to 526 - * the actual input color, but it's almost as good. A zero in the cache 527 - * indicates we haven't found the nearest color for that cell yet; the array 528 - * is cleared to zeroes before starting the mapping pass. When we find the 529 - * nearest color for a cell, its colormap index plus one is recorded in the 530 - * cache for future use. The pass2 scanning routines call fill_inverse_cmap 531 - * when they need to use an unfilled entry in the cache. 532 - * 533 - * Our method of efficiently finding nearest colors is based on the "locally 534 - * sorted search" idea described by Heckbert and on the incremental distance 535 - * calculation described by Spencer W. Thomas in chapter III.1 of Graphics 536 - * Gems II (James Arvo, ed. Academic Press, 1991). Thomas points out that 537 - * the distances from a given colormap entry to each cell of the histogram can 538 - * be computed quickly using an incremental method: the differences between 539 - * distances to adjacent cells themselves differ by a constant. This allows a 540 - * fairly fast implementation of the "brute force" approach of computing the 541 - * distance from every colormap entry to every histogram cell. Unfortunately, 542 - * it needs a work array to hold the best-distance-so-far for each histogram 543 - * cell (because the inner loop has to be over cells, not colormap entries). 544 - * The work array elements have to be ints, so the work array would need 545 - * 256Kb at our recommended precision. This is not feasible in DOS machines. 546 - 547 -[ 256*1024/4 = 65,536 ] 548 - 549 - * To get around these problems, we apply Thomas' method to compute the 550 - * nearest colors for only the cells within a small subbox of the histogram. 551 - * The work array need be only as big as the subbox, so the memory usage 552 - * problem is solved. Furthermore, we need not fill subboxes that are never 553 - * referenced in pass2; many images use only part of the color gamut, so a 554 - * fair amount of work is saved. An additional advantage of this 555 - * approach is that we can apply Heckbert's locality criterion to quickly 556 - * eliminate colormap entries that are far away from the subbox; typically 557 - * three-fourths of the colormap entries are rejected by Heckbert's criterion, 558 - * and we need not compute their distances to individual cells in the subbox. 559 - * The speed of this approach is heavily influenced by the subbox size: too 560 - * small means too much overhead, too big loses because Heckbert's criterion 561 - * can't eliminate as many colormap entries. Empirically the best subbox 562 - * size seems to be about 1/512th of the histogram (1/8th in each direction). 563 - * 564 - * Thomas' article also describes a refined method which is asymptotically 565 - * faster than the brute-force method, but it is also far more complex and 566 - * cannot efficiently be applied to small subboxes. It is therefore not 567 - * useful for programs intended to be portable to DOS machines. On machines 568 - * with plenty of memory, filling the whole histogram in one shot with Thomas' 569 - * refined method might be faster than the present code --- but then again, 570 - * it might not be any faster, and it's certainly more complicated. 571 - */ 572 - 573 -/* log2(histogram cells in update box) for each axis; this can be adjusted */ 574 -#define BOX_R_LOG (PRECISION_R-3) 575 -#define BOX_G_LOG (PRECISION_G-3) 576 -#define BOX_B_LOG (PRECISION_B-3) 577 - 578 -#define BOX_R_ELEMS (1<<BOX_R_LOG) /* # of hist cells in update box */ 579 -#define BOX_G_ELEMS (1<<BOX_G_LOG) 580 -#define BOX_B_ELEMS (1<<BOX_B_LOG) 581 - 582 -#define BOX_R_SHIFT (R_SHIFT + BOX_R_LOG) 583 -#define BOX_G_SHIFT (G_SHIFT + BOX_G_LOG) 584 -#define BOX_B_SHIFT (B_SHIFT + BOX_B_LOG) 585 - 586 -/* 587 - * The next three routines implement inverse colormap filling.
