[adam@gimp.org] + * + * 2004-12-12 - Use a slower but much nicer technique for finding the + * two best colors to dither between when using fixed/positional + * dither methods. Makes positional dither much less lame. [adam@gimp.org] + * + * 2002-02-10 - Quantizer version 3.0 (the rest of the commit started + * a year ago -- whoops). Divide colors within CIE L*a*b* space using + * CPercep module (cpercep.[ch]), color-match and dither likewise, + * change the underlying box selection criteria and division point + * logic, bump luminance precision upwards, etc.etc. Generally + * chooses a much richer color set, especially for low numbers of + * colors. n.b.: Less luminance-sloppy in straight remapping which is + * good for color but a bit worse for high-frequency detail (that's + * partly what fs-dithering is for -- use it). [adam@gimp.org] + * + * 2001-03-25 - Define accessor function/macro for histogram reads and + * writes. This slows us down a little because we avoid some of the + * dirty tricks we used when we knew that the histogram was a straight + * 3d array, so I've recovered some of the speed loss by implementing + * a 5d accessor function with good locality of reference. This change + * is the first step towards quantizing in a more interesting colorspace + * than frumpy old RGB. [Adam] + * + * 2000/01/30 - Use palette_selector instead of option_menu for custom + * palette. Use libgimp callback functions. [Sven] + * + * 99/09/01 - Created a low-bleed FS-dither option. [Adam] + * + * 99/08/29 - Deterministic color dithering to arbitrary palettes. + * Ideal for animations that are going to be delta-optimized or simply + * don't want to look 'busy' in static areas. Also a bunch of bugfixes + * and tweaks. [Adam] + * + * 99/08/28 - Deterministic alpha dithering over layers, reduced bleeding + * of transparent values into opaque values, added optional stage to + * remove duplicate or unused color entries from final colormap. [Adam] + * + * 99/02/24 - Many revisions to the box-cut quantizer used in RGB->INDEXED + * conversion. Box to be cut is chosen on the basis of possessing an axis + * with the largest sum of weighted perceptible error, rather than based on + * volume or population. The box is split along this axis rather than its + * longest axis, at the point of error mean rather than simply at its centre. + * Error-limiting in the F-S dither has been disabled - it may become optional + * again later. If you're convinced that you have an image where the old + * dither looks better, let me know. [Adam] + * + * 99/01/10 - Hourglass... [Adam] + * + * 98/07/25 - Convert-to-indexed now remembers the last invocation's + * settings. Also, GRAY->INDEXED is more flexible. [Adam] + * + * 98/07/05 - Sucked the warning about quantizing to too many colors into + * a text widget embedded in the dialog, improved intelligence of dialog + * to default 'custom palette' selection to 'Web' if available, and + * in this case not bother to present the native WWW-palette radio + * button. [Adam] + * + * 98/04/13 - avoid a division by zero when converting an empty gray-scale + * image (who would like to do such a thing anyway??) [Sven ] + * + * 98/03/23 - fixed a longstanding fencepost - hopefully the *right* + * way, *again*. [Adam] + * + * 97/11/14 - added a proper pdb interface and support for dithering + * to custom palettes (based on a patch by Eric Hernes) [Yosh] + * + * 97/11/04 - fixed the accidental use of the color-counting case + * when palette_type is WEB or MONO. [Adam] + * + * 97/10/25 - color-counting implemented (could use some hashing, but + * performance actually seems okay) - now RGB->INDEXED conversion isn't + * destructive if it doesn't have to be. [Adam] + * + * 97/10/14 - fixed divide-by-zero when converting a completely transparent + * RGB image to indexed. [Adam] + * + * 97/07/01 - started todo/revision log. Put code back in to + * eliminate full-alpha pixels from RGB histogram. + * [Adam D. Moss - adam@gimp.org] + */ + + /* TODO for Convert: + * + * . Tweak, tweak, tweak.

All colors within a + * histogram cell will be mapped to the same colormap entry, namely the one + * closest to the cell's center. This may not be quite the closest entry to + * the actual input color, but it's almost as good. A zero in the cache + * indicates we haven't found the nearest color for that cell yet; the array + * is cleared to zeroes before starting the mapping pass. When we find the + * nearest color for a cell, its colormap index plus one is recorded in the + * cache for future use. The pass2 scanning routines call fill_inverse_cmap + * when they need to use an unfilled entry in the cache. + * + * Our method of efficiently finding nearest colors is based on the "locally + * sorted search" idea described by Heckbert and on the incremental distance + * calculation described by Spencer W. Thomas in chapter III.1 of Graphics + * Gems II (James Arvo, ed. Academic Press, 1991). Thomas points out that + * the distances from a given colormap entry to each cell of the histogram can + * be computed quickly using an incremental method: the differences between + * distances to adjacent cells themselves differ by a constant. This allows a + * fairly fast implementation of the "brute force" approach of computing the + * distance from every colormap entry to every histogram cell. Unfortunately, + * it needs a work array to hold the best-distance-so-far for each histogram + * cell (because the inner loop has to be over cells, not colormap entries). + * The work array elements have to be ints, so the work array would need + * 256Kb at our recommended precision. This is not feasible in DOS machines. + * + * To get around these problems, we apply Thomas' method to compute the + * nearest colors for only the cells within a small subbox of the histogram. + * The work array need be only as big as the subbox, so the memory usage + * problem is solved. Furthermore, we need not fill subboxes that are never + * referenced in pass2; many images use only part of the color gamut, so a + * fair amount of work is saved. An additional advantage of this + * approach is that we can apply Heckbert's locality criterion to quickly + * eliminate colormap entries that are far away from the subbox; typically + * three-fourths of the colormap entries are rejected by Heckbert's criterion, + * and we need not compute their distances to individual cells in the subbox. + * The speed of this approach is heavily influenced by the subbox size: too + * small means too much overhead, too big loses because Heckbert's criterion + * can't eliminate as many colormap entries.

This function takes a pointer to a + * GimpPaintCoreLoopsParams structure, providing the parameters for the + * algorithms, and a GimpPaintCoreLoopsAlgorithm bitset, which specifies the + * set of algorithms to run; currently, the algorithms are always run in a + * fixed order. For convenience, we provide public functions for the + * individual algorithms, but they're merely wrappers around + * gimp_paint_core_loops_process(). + * + * We use some C++ magic to statically generate specialized versions of + * gimp_paint_core_loops_process() for all possible combinations of algorithms, + * and, where relevant, formats and input parameters, and to dispatch to the + * correct version at runtime. + * + * To achieve this, each algorithm provides two components: + * + * - The algorithm class template, which implements the algorithm, following + * a common interface. See the AlgorithmBase class for a description of + * the interface. Each algorithm class takes its base class as a template + * parameter, which allows us to construct a class hierarchy corresponding + * to a specific set of algorithms. Some classes in the hierarchy are not + * algorithms themselves, but are rather helpers, which provide some + * functionality to the algorithms further down the hierarchy, such as + * access to specific buffers. + * + * - A dispatch function, which takes the input parameters, the requested set + * of algorithms, the (type of) the current algorithm hierarchy, and a + * visitor object. The function calls the visitor with a (potentially) + * modified hierarchy, depending on the input. Ihe dispatch function for + * an algorithm checks if the requested set of algorithms contains a + * certain algorithm, adds the said algorithm to the hierarchy accordingly, + * and calls the visitor with the new hierarchy. See the AlgorithmDispatch + * class, which provides a dispatch-function implementation which + * algorithms can use instead of providing their own dispatch function. + * + * Helper classes in the hierarchy may also provide dispatch functions, + * which likewise modify the hierarchy based on the input parameters. For + * example, the dispatch_paint_mask() function adds a certain PaintMask + * specialization to the hierarchy, depending on the format of the paint + * mask buffer; this can be used to specialize algorithms based on the mask + * format; an algorithm that depends on the paint mask may dispatch through + * this function, before modifying the hierarchy itself. + * + * The dispatch() function is used to construct an algorithm hierarchy by + * dispatching through a list of functions. gimp_paint_core_loops_process() + * calls dispatch() with the full list of algorithm dispatch functions, + * receiving in return the algorithm hierarchy matching the input.
