One of it's primary purposes is a teaching tool students will use to reimplement, and experiment with, simple image processing operations. The best documentation for the package is the examples catalog, all of lua, documented at http://www.lua.org/ is avaiable, as well as the following image manipulation functions: set_hsl (x, y, h, s, l) set_hsv (x, y, h, s, v) set_lab (x, y, l, a, b) set_rgb (x, y, r, g, b) set_rgba (x, y, r, g, b, a) set_value (x, y, value) set_alpha (x, y, alpha) (lua allows multiple return, I use that to illustrate the return value of the pixel data querying functions) h,s,l = get_hsl (x, y) h,s,v = get_hsv (x, y) l,a,b = get_lab (x, y) r,g,b = get_rgb (x, y) r,g,b,a = get_rgba (x, y) value = get_value (x, y) alpha = get_alpha (x, y) flush () apply the current processing (which means that pixels retrieved with get_ functions, will get the data set with set_ functions and not original data, useful for multipass implementations, the global variables width and height are set to the pixel dimensions of the drawable being modified. progress (amount) Calling the function progress(val) with a number between 0.0 and 1.0 will give the user feedback about how much of the image is processed. Animation ========= An extra feature of gluas is animation, by pressing shift+ctrl+A you can control some additional options. The number of frames generated, and the time value to use when doing a preview. From within the code the time value can be accessed through the global variable 'time' which varies from 0.0 at the start of the animation to 1.0 at the end of the animation. To make the animation "ping-pong" insert code similar to if time>0.5 then time=0.5-(time-0.5) time=time*2 else time=time*2 end at the top of your script.

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the `--target=TYPE' option to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc will cause the specified gcc to be used as the C compiler (unless it is overridden in the site shell script). `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. gluas-0.1.20/Makefile.am0000644000175000017500000000017610222610577011670 00000000000000## Process this file with automake to produce Makefile.in SUBDIRS = src EXTRA_DIST = \ BUGS \ HACKING \ autogen.sh gluas-0.1.20/NEWS0000644000175000017500000000010610207115267010323 00000000000000Here you can collect the new features of your current plugin release. gluas-0.1.20/TODO0000644000175000017500000000174210207115267010323 00000000000000This is your plugin's TODO list. .----------------------------------. |load | save | test | |----------------------------------| |for x=0, width-1 | | for y=0, height -1 | | r,g,b = get_rgb (x,y) | | | | set_rgb (x,y, r,g,b) | | end | |end | | | | | | | | | | | | | |----------------------------------| | Help | | Cancel | OK | `----------------------------------' r,g,b get_rgb (x,y) r,g,b,a get_rgba (x,y,r,g,b,a) v get_value (x,y) l,a,b get_lab (x,y) alpha get_alpha (x,y) set_rgb (x,y,r,g,b) set_rgba (x,y,r,g,b,a) set_lab (x,y,l,a,b) set_value (x,y,value) set_alpha (x,y,alpha) progress (ratio_done) gluas-0.1.20/aclocal.m40000644000175000017500000012220611120222023011452 00000000000000# generated automatically by aclocal 1.7.9 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002 # Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. # Like AC_CONFIG_HEADER, but automatically create stamp file. -*- Autoconf -*- # Copyright 1996, 1997, 2000, 2001 Free Software Foundation, Inc. # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Beta software can be found at alpha.gnu.org. If you are accessing gluas via CVS, then you will need to take several steps to get it to compile. You can do all these steps at once by running: ./autogen.sh Basically this does the following for you: aclocal; automake; autoconf The above commands create the "configure" script. Now you can run the configure script to create all the Makefiles. Before running autogen.sh or configure, make sure you have libtool in your path. Also make sure gimp-2.0.m4 is in the same --prefix relative to your automake installation. Note that autogen.sh runs configure for you. If you wish to pass options like --prefix=/usr to configure you can give those options to autogen.sh and they will be passed on to configure. gluas-0.1.20/autogen.sh0000755000175000017500000001066510222610441011627 00000000000000#!/bin/sh # This script does all the magic calls to automake/autoconf and # friends that are needed to configure a cvs checkout.

Moss: adam@gimp.org This code module concerns itself with conversion from a hard-coded RGB colour space (sRGB by default) to CIE L*a*b* and back again with (primarily) precision and (secondarily) speed, oriented largely towards the purposes of quantifying the PERCEPTUAL difference between two arbitrary RGB colours with a minimum of fuss. Motivation One: The author is disheartened at the amount of graphics processing software around which uses weighted or non-weighted Euclidean distance between co-ordinates within a (poorly-defined) RGB space as the basis of what should really be an estimate of perceptual difference to the human eye. Certainly it's fast to do it that way, but please think carefully about whether your particular application should be tolerating sloppy results for the sake of real-time response. Motivation Two: Lack of tested, re-usable and free code available for this purpose. The difficulty in finding something similar to CPercep with a free license motivated this project; I hope that this code also serves to illustrate how to perform the R'G'B'->XYZ->L*a*b*->XYZ->R'G'B' transformation correctly since I was distressed to note how many of the equations and code snippets on the net were omitting the reverse transform and/or were using incorrectly-derived or just plain wrong constants.
