Welcome

+

+Welcome to the official SFML.Net documentation. Here you will find a detailed +description of all the SFML.Net classes.
+If you are looking for tutorials, help or whatever, you can visit the official website +at www.sfml-dev.org. +

+ +

Short example

+

+Here is a short example in C#, to show you how simple it is to use SFML.Net : +

+ +
+using System;
+using SFML.Audio;
+using SFML.Window;
+using SFML.Graphics;
+
+namespace Example
+{
+    class Program
+    {
+        static void OnClose(object sender, EventArgs e)
+        {
+            // Close the window when OnClose event is received
+            RenderWindow window = (RenderWindow)sender;
+            window.Close();
+        }
+
+        static void Main(string[] args)
+        {
+            // Create the main window
+            RenderWindow app = new RenderWindow(new VideoMode(800, 600), "SFML window");
+            app.Closed += new EventHandler(OnClose);
+
+            // Load a sprite to display
+            Image  image  = new Image("cute_image.jpg");
+            Sprite sprite = new Sprite(image);
+
+            // Create a graphical string to display
+            Font     arial = new Font("arial.ttf");
+            String2D text  = new String2D("Hello SFML.Net", arial);
+
+            // Load a music to play
+            Music music = new Music("nice_music.ogg");
+            music.Play();
+
+            // Start the game loop
+            while (app.IsOpened())
+            {
+                // Process events
+                app.DispatchEvents();
+
+                // Clear screen
+                app.Clear();
+
+                // Draw the sprite
+                app.Draw(sprite);
+
+                // Draw the string
+                app.Draw(text);
+
+                // Update the window
+                app.Display();
+            }
+        }
+    }
+}

Only scalable + * outlines will be loaded when available, and scaled, hinted, or + * rendered depending on other bit flags. + * + * This does not prevent you from rendering outlines to bitmaps + * with @FT_LOAD_RENDER, however. + * + * FT_LOAD_VERTICAL_LAYOUT :: + * Prepare the glyph image for vertical text layout.

You shouldn't need this in a typical application, since it + * is mostly used to experiment with its algorithm. + * + * FT_LOAD_CROP_BITMAP :: + * Indicates that the glyph loader should try to crop the bitmap (i.e., + * remove all space around its black bits) when loading it. This is + * only useful when loading embedded bitmaps in certain fonts, since + * bitmaps rendered with @FT_LOAD_RENDER are always cropped by default. + * + * FT_LOAD_PEDANTIC :: + * Indicates that the glyph loader should perform pedantic + * verifications during glyph loading, rejecting invalid fonts. This + * is mostly used to detect broken glyphs in fonts. By default, + * FreeType tries to handle broken fonts also. + * + * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH :: + * Indicates that the glyph loader should ignore the global advance + * width defined in the font. For historical reasons (to support + * buggy CJK fonts), FreeType uses the value of the `advanceWidthMax' + * field in the `htmx' table for all glyphs if the font is monospaced. + * Activating this flags makes FreeType use the metric values given in + * the `htmx' table. + * + * FT_LOAD_NO_RECURSE :: + * This flag is only used internally. It merely indicates that the + * glyph loader should not load composite glyphs recursively. Instead, + * it should set the `num_subglyph' and `subglyphs' values of the glyph + * slot accordingly, and set "glyph->format" to + * @FT_GLYPH_FORMAT_COMPOSITE. + * + * The description of sub-glyphs is not available to client + * applications for now. + * + * FT_LOAD_IGNORE_TRANSFORM :: + * Indicates that the glyph loader should not try to transform the + * loaded glyph image. This doesn't prevent scaling, hinting, or + * rendering. + * + * FT_LOAD_MONOCHROME :: + * This flag is used with @FT_LOAD_RENDER to indicate that you want + * to render a 1-bit monochrome glyph bitmap from a vectorial outline. + * + * Note that this has no effect on the hinting algorithm used by the + * glyph loader. You should better use @FT_LOAD_TARGET_MONO if you + * want to render monochrome-optimized glyph images instead. + * + * FT_LOAD_LINEAR_DESIGN :: + * Return the linearly scaled metrics expressed in original font units + * instead of the default 16.16 pixel values. + * + * FT_LOAD_NO_AUTOHINT :: + * Indicates that the auto-hinter should never be used to hint glyph + * outlines. This doesn't prevent native format-specific hinters from + * being used. This can be important for certain fonts where unhinted + * output is better than auto-hinted one. + * + * FT_LOAD_TARGET_NORMAL :: + * Use hinting for @FT_RENDER_MODE_NORMAL. + * + * FT_LOAD_TARGET_LIGHT :: + * Use hinting for @FT_RENDER_MODE_LIGHT. + * + * FT_LOAD_TARGET_MONO :: + * Use hinting for @FT_RENDER_MODE_MONO. + * + * FT_LOAD_TARGET_LCD :: + * Use hinting for @FT_RENDER_MODE_LCD. + * + * FT_LOAD_TARGET_LCD_V :: + * Use hinting for @FT_RENDER_MODE_LCD_V. + */ +#define FT_LOAD_DEFAULT 0x0 +#define FT_LOAD_NO_SCALE 0x1 +#define FT_LOAD_NO_HINTING 0x2 +#define FT_LOAD_RENDER 0x4 +#define FT_LOAD_NO_BITMAP 0x8 +#define FT_LOAD_VERTICAL_LAYOUT 0x10 +#define FT_LOAD_FORCE_AUTOHINT 0x20 +#define FT_LOAD_CROP_BITMAP 0x40 +#define FT_LOAD_PEDANTIC 0x80 +#define FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH 0x200 +#define FT_LOAD_NO_RECURSE 0x400 +#define FT_LOAD_IGNORE_TRANSFORM 0x800 +#define FT_LOAD_MONOCHROME 0x1000 +#define FT_LOAD_LINEAR_DESIGN 0x2000 + + /* temporary hack! */ +#define FT_LOAD_SBITS_ONLY 0x4000 +#define FT_LOAD_NO_AUTOHINT 0x8000U + + /* */ + +#define FT_LOAD_TARGET_( x ) ( (FT_Int32)( (x) & 15 ) << 16 ) +#define FT_LOAD_TARGET_MODE( x ) ( (FT_Render_Mode)( ( (x) >> 16 ) & 15 ) ) + +#define FT_LOAD_TARGET_NORMAL FT_LOAD_TARGET_( FT_RENDER_MODE_NORMAL ) +#define FT_LOAD_TARGET_LIGHT FT_LOAD_TARGET_( FT_RENDER_MODE_LIGHT ) +#define FT_LOAD_TARGET_MONO FT_LOAD_TARGET_( FT_RENDER_MODE_MONO ) +#define FT_LOAD_TARGET_LCD FT_LOAD_TARGET_( FT_RENDER_MODE_LCD ) +#define FT_LOAD_TARGET_LCD_V FT_LOAD_TARGET_( FT_RENDER_MODE_LCD_V ) + + /* */ + + + /*************************************************************************/ + /* */ + /* <Function> */ + /* FT_Set_Transform */ + /* */ + /* <Description> */ + /* A function used to set the transformation that is applied to glyph */ + /* images when they are loaded into a glyph slot through */ + /* @FT_Load_Glyph. */ + /* */ + /* <InOut> */ + /* face :: A handle to the source face object. */ + /* */ + /* <Input> */ + /* matrix :: A pointer to the transformation's 2x2 matrix.

Introduction

+

I apologize for how limited this documentation is, but as this extension is primarily a simple wrapper around SFML's C++ classes, I will rely on SFML's documentation to explain more detail about the classes and methods. This documentation is simply meant to explain which classes and methods are available in Ruby, as well as what changes have been made during the translation from C++ to Ruby.

+

As Ruby doesn't support native threading and has its own networking classes, I only exposed certain classes in the system, window, graphics, and audio libraries. For most exposed classes, the only changes I made were to make the methods start with a lower-case letter. For classes with simple Get/Set methods, I often drop the Get and Set to allow you to use sprite.left and sprite.left=. I also added a few to_i, to_f, and to_s methods where it seemed appropriate. Last but not least, I added an each iterator to VideoMode.

+

In addition to the C++ classes I exposed, I also added two helper classes in RubySFML.rb, one for rendering tiled sprites, and the other for dealing with sprites that use 2D velocity/accelerate calculations (TSprite and VSprite respectively).

+

Tips for Windows Users

+

For the Windows users out there, I apologize for not being compatible with the one-click installer, but it's being built with Visual Studio 6.0, which is ridiculously old and not compatible with any of the SFML libraries. There's a free version of Visual Studio 2005 available, and the Ruby source compiles very smoothly with it, so I can't think of a good excuse for the one-click installer to still be using 6.0.

+

On the bright side, you can distribute your game in a self-sufficient package by zipping it up with the bin and lib folders that come with the Windows binary version of this extension. Add a simple installer that creates a program group icon that runs "%install_path%\bin\ruby.exe %install_path%\my_game.rb", and you're all set. Oh yeah, OpenAL needs to be installed on any machine running this. Fortunately it is a very small/simple install, and it should be easy for you to either bundle it with your distribution or provide a link for your users to download it. All of this keeps your users from having to download/run the one-click installer, install all the necessary extensions, worry about compatibility issues, etc. It is likely that very few Windows users will ever play your game if you don't provide them everything they need to run it, so it's probably better this way.

+

Note: This custom build of Ruby does have gems and zlib (which is required by gems), but no other extensions are installed. Feel free to install any other gems/extensions you need (native mswin32 gems compiled with Visual Studio 6.0 may not work). Keep in mind that many gems often have large doc, examples, and test folders. Deleting these unnecessary folders, along with the gem cache folder, can significantly shrink the size of the file you're distributing.

RubySFML Sample Code

+ 
+# Include the RubySFML extension
+require "RubySFML"
+include SFML
+
+# Create the main window
+mode = VideoMode.new 800, 600, 32
+window = RenderWindow.new mode, "RubySFML Test", false
+
+# Load a sprite to display
+image = Image.new "cute_image.jpg"
+sprite = Sprite.new image
+ 
+# Create a graphical string to display
+text = Text.new "Hello SFML", "arial.ttf", 50
+ 
+# Load a music and start playing it
+music = Music.new "nice_music.ogg"
+music.play
+ 
+# Start the game loop
+running = true
+while running
+	while event = window.getEvent
+		running = false if event.type == Event::Close
+	end
+ 
+	# Draw the sprite, then the text, and update the window
+	window.draw sprite
+	window.draw text
+	window.display
+end

Introduction

+

Cette documentation est assez courte, mais étant donné que cette extension n'est qu'une simple encapsulation des classes C++ de SFML, il est conseillé de se baser sur la documentation SFML pour obtenir plus de détails sur les classes et les fonctions. Cette documentation a simplement pour but de détailler les classes et fonctions qui sont présentes dans l'extension RubySFML, ainsi que de décrire les changements qui ont été effectués durant la traduction C++ vers Ruby.

+

Etant donné que Ruby ne supporte pas les threads et possède ses propres classes pour le réseau, seules certaines classes des modules système, fenêtrage, graphisme et audio sont exposées. Pour la plupart des classes, les seuls changements effectués ont été de faire débuter les noms des fonctions par une minuscule. Pour les classes possédant des accesseurs simples, ceux-ci ont souvent été abandonnés pour utiliser une syntaxe plus simple (par exemple sprite.left = ...). Quelques fonctions to_i, to_f et to_s ont étalement été ajoutées là où cela semblait pertinent. Enfin, un itérateur "each" a été ajouté à VideoMode.

+

En plus des classes C++ exposées, deux classes utiles ont également été ajoutées à RubySFML.rb, l'une pour afficher des sprites à base de tuiles, et l'autre pour gérer les sprites utilisant des calculs de vitesse / acceleration (respectivement TSprite et VSprite).

+ +

Astuces pour les utilisateurs Windows

+

Pour les utilisateurs Windows, nous regrettons de ne pas pouvoir être compatibles avec l'installeur "one-click", mais celui-ci est compilé avec Visual Studio 6.0, qui est ridiculeusement vieux et incompatible avec les bibliothèques SFML. Il existe une version gratuite de Visual Studio 2005, et les sources de Ruby compilent parfaitement avec celle-ci, on ne peut donc trouver aucune bonne excuse à l'installeur pour toujours utiliser Visual C++ 6.0.

+

La bonne nouvelle est que vous pouvez distribuer vos applications dans une archive qui se suffit à elle-même, en incluant les répertoires "bin" et "lib" qui sont inclus dans la version Windows de cette extension. Ajoutez un installeur simple qui crée une icône du menu démarrer exécutant "%install_path%\bin\ruby.exe %install_path%\my_game.rb", et tout sera parfait. Oh, encore une chose, OpenAL doit être installé pour exécuter les programmes utilisant RubySFML. Heureusement, il s'agit d'un installeur extrêmement petit et simple, et vous pourrez sans problème le fournir dans vos installations ou donner un lien pour le télécharger. Tout ceci évite à vos utilisateurs d'avoir à télécharger / exécuter l'installeur "one-click", installer toutes les extensions nécessaires, s'occuper des problèmes de compatibilité, etc. Il est probable que très peu d'utilisateurs Windows utilisent vos applications si vous ne leur fournissez pas tout ce dont ils ont besoin, c'est donc probablement mieux de cette manière.

+

Note : cette compilation perso de Ruby ne contient pas gems et zlib (qui est recquis par gems), mais aucune autre extension n'est installée. N'hésitez pas à installer n'importe quelle autre gems / extension dont vous auriez besoin (les gems mswin32 compilés avec Visual Studio 6.0 ne fonctionneront probablement pas). Gardez en tête que beaucoup de gems ont une documentation conséquente, des exemples et des répertoires de test. Supprimer ces répertoires innutiles, ainsi que le répertoire cache des gems, peut réduire de manière significative la taille des fichiers que vous distribuez.

Exemple de code RubySFML

+
+# On inclut l'extension RubySFML
+require "RubySFML"
+include SFML

+# On crée la fenêtre principale
+mode = VideoMode.new 800, 600, 32
+window = RenderWindow.new mode, "RubySFML Test", false
+
+# On charge un sprite à afficher
+image = Image.new "cute_image.jpg"
+sprite = Sprite.new image
+ 
+# On crée une chaîne graphique à afficher
+text = Text.new "Hello SFML", "arial.ttf", 50
+ 
+# On charge une musique et on commence à la jouer
+music = Music.new "nice_music.ogg"
+music.play
+ 
+# On démarre la boucle principale
+running = true
+while running
+	while event = window.getEvent
+		running = false if event.type == Event::Close
+	end
+ 
+	# On dessine le sprite, le texte, puis on met à jour la fenêtre
+	window.draw sprite
+	window.draw text
+	window.display

The gzip format is different from the zlib format. gzip is a + gzip wrapper, documented in RFC 1952, wrapped around a deflate stream. + + This library can optionally read and write gzip streams in memory as well. + + The zlib format was designed to be compact and fast for use in memory + and on communications channels. The gzip format was designed for single- + file compression on file systems, has a larger header than zlib to maintain + directory information, and uses a different, slower check method than zlib. + + The library does not install any signal handler.

Nonetheless, the main controller is not + * trivial. Its responsibility is to provide context rows for upsampling/ + * rescaling, and doing this in an efficient fashion is a bit tricky. + * + * Postprocessor input data is counted in "row groups". A row group + * is defined to be (v_samp_factor * DCT_scaled_size / min_DCT_scaled_size) + * sample rows of each component. (We require DCT_scaled_size values to be + * chosen such that these numbers are integers. In practice DCT_scaled_size + * values will likely be powers of two, so we actually have the stronger + * condition that DCT_scaled_size / min_DCT_scaled_size is an integer.) + * Upsampling will typically produce max_v_samp_factor pixel rows from each + * row group (times any additional scale factor that the upsampler is + * applying). + * + * The coefficient controller will deliver data to us one iMCU row at a time; + * each iMCU row contains v_samp_factor * DCT_scaled_size sample rows, or + * exactly min_DCT_scaled_size row groups. (This amount of data corresponds + * to one row of MCUs when the image is fully interleaved.) Note that the + * number of sample rows varies across components, but the number of row + * groups does not. Some garbage sample rows may be included in the last iMCU + * row at the bottom of the image. + * + * Depending on the vertical scaling algorithm used, the upsampler may need + * access to the sample row(s) above and below its current input row group. + * The upsampler is required to set need_context_rows TRUE at global selection + * time if so. When need_context_rows is FALSE, this controller can simply + * obtain one iMCU row at a time from the coefficient controller and dole it + * out as row groups to the postprocessor. + * + * When need_context_rows is TRUE, this controller guarantees that the buffer + * passed to postprocessing contains at least one row group's worth of samples + * above and below the row group(s) being processed. Note that the context + * rows "above" the first passed row group appear at negative row offsets in + * the passed buffer. At the top and bottom of the image, the required + * context rows are manufactured by duplicating the first or last real sample + * row; this avoids having special cases in the upsampling inner loops. + * + * The amount of context is fixed at one row group just because that's a + * convenient number for this controller to work with. The existing + * upsamplers really only need one sample row of context. An upsampler + * supporting arbitrary output rescaling might wish for more than one row + * group of context when shrinking the image; tough, we don't handle that. + * (This is justified by the assumption that downsizing will be handled mostly + * by adjusting the DCT_scaled_size values, so that the actual scale factor at + * the upsample step needn't be much less than one.) + * + * To provide the desired context, we have to retain the last two row groups + * of one iMCU row while reading in the next iMCU row. (The last row group + * can't be processed until we have another row group for its below-context, + * and so we have to save the next-to-last group too for its above-context.) + * We could do this most simply by copying data around in our buffer, but + * that'd be very slow. We can avoid copying any data by creating a rather + * strange pointer structure. Here's how it works. We allocate a workspace + * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number + * of row groups per iMCU row). We create two sets of redundant pointers to + * the workspace. Labeling the physical row groups 0 to M+1, the synthesized + * pointer lists look like this: + * M+1 M-1 + * master pointer --> 0 master pointer --> 0 + * 1 1 + * ... ... + * M-3 M-3 + * M-2 M + * M-1 M+1 + * M M-2 + * M+1 M-1 + * 0 0 + * We read alternate iMCU rows using each master pointer; thus the last two + * row groups of the previous iMCU row remain un-overwritten in the workspace. + * The pointer lists are set up so that the required context rows appear to + * be adjacent to the proper places when we pass the pointer lists to the + * upsampler. + * + * The above pictures describe the normal state of the pointer lists. + * At top and bottom of the image, we diddle the pointer lists to duplicate + * the first or last sample row as necessary (this is cheaper than copying + * sample rows around). + * + * This scheme breaks down if M < 2, ie, min_DCT_scaled_size is 1. In that + * situation each iMCU row provides only one row group so the buffering logic + * must be different (eg, we must read two iMCU rows before we can emit the + * first row group). For now, we simply do not support providing context + * rows when min_DCT_scaled_size is 1.

Lane. + * This file is part of the Independent JPEG Group's software. + * For conditions of distribution and use, see the accompanying README file. + * + * This file contains a floating-point implementation of the + * forward DCT (Discrete Cosine Transform). + * + * This implementation should be more accurate than either of the integer + * DCT implementations. However, it may not give the same results on all + * machines because of differences in roundoff behavior. Speed will depend + * on the hardware's floating point capacity. + * + * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT + * on each column. Direct algorithms are also available, but they are + * much more complex and seem not to be any faster when reduced to code. + * + * This implementation is based on Arai, Agui, and Nakajima's algorithm for + * scaled DCT. Their original paper (Trans. IEICE E-71(11):1095) is in + * Japanese, but the algorithm is described in the Pennebaker & Mitchell + * JPEG textbook (see REFERENCES section in file README). The following code + * is based directly on figure 4-8 in P&M. + * While an 8-point DCT cannot be done in less than 11 multiplies, it is + * possible to arrange the computation so that many of the multiplies are + * simple scalings of the final outputs.

The intended implementation is that there is a strip buffer in + * memory (as high as is possible given the desired memory limit), plus a + * backing file that holds the rest of the array. + * + * The request_virt_array routines are told the total size of the image and + * the maximum number of rows that will be accessed at once. The in-memory + * buffer must be at least as large as the maxaccess value. + * + * The request routines create control blocks but not the in-memory buffers. + * That is postponed until realize_virt_arrays is called. At that time the + * total amount of space needed is known (approximately, anyway), so free + * memory can be divided up fairly. + * + * The access_virt_array routines are responsible for making a specific strip + * area accessible (after reading or writing the backing file, if necessary). + * Note that the access routines are told whether the caller intends to modify + * the accessed strip; during a read-only pass this saves having to rewrite + * data to disk.

To keep the histogram to a reasonable + * size, we reduce the precision of the input; typical practice is to retain + * 5 or 6 bits per color, so that 8 or 4 different input values are counted + * in the same histogram cell. + * + * Next, the color-selection step begins with a box representing the whole + * color space, and repeatedly splits the "largest" remaining box until we + * have as many boxes as desired colors. Then the mean color in each + * remaining box becomes one of the possible output colors. + * + * The second pass over the image maps each input pixel to the closest output + * color (optionally after applying a Floyd-Steinberg dithering correction). + * This mapping is logically trivial, but making it go fast enough requires + * considerable care. + * + * Heckbert-style quantizers vary a good deal in their policies for choosing + * the "largest" box and deciding where to cut it. The particular policies + * used here have proved out well in experimental comparisons, but better ones + * may yet be found. + * + * In earlier versions of the IJG code, this module quantized in YCbCr color + * space, processing the raw upsampled data without a color conversion step. + * This allowed the color conversion math to be done only once per colormap + * entry, not once per pixel. However, that optimization precluded other + * useful optimizations (such as merging color conversion with upsampling) + * and it also interfered with desired capabilities such as quantizing to an + * externally-supplied colormap. We have therefore abandoned that approach. + * The present code works in the post-conversion color space, typically RGB. + * + * To improve the visual quality of the results, we actually work in scaled + * RGB space, giving G distances more weight than R, and R in turn more than + * B. To do everything in integer math, we must use integer scale factors. + * The 2/3/1 scale factors used here correspond loosely to the relative + * weights of the colors in the NTSC grayscale equation. + * If you want to use this code to quantize a non-RGB color space, you'll + * probably need to change these scale factors. + */ + +#define R_SCALE 2 /* scale R distances by this much */ +#define G_SCALE 3 /* scale G distances by this much */ +#define B_SCALE 1 /* and B by this much */ + +/* Relabel R/G/B as components 0/1/2, respecting the RGB ordering defined + * in jmorecfg.h.

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 INT32s, 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. Empirically the best subbox + * size seems to be about 1/512th of the histogram (1/8th in each direction). + * + * Thomas' article also describes a refined method which is asymptotically + * faster than the brute-force method, but it is also far more complex and + * cannot efficiently be applied to small subboxes.

This + * would not only allow one to eliminate half of the memory + * writes for odd passes (that is, pass == odd), it may also + * eliminate some unaligned-data-access exceptions (assuming + * there's a penalty for not aligning 64-bit accesses on + * 64-bit boundaries). The only catch is that the "leftover" + * pixel(s) at the end of the row would have to be saved, + * but there are enough unused MMX registers in every case, + * so this is not a problem. A further benefit is that the + * post-MMX cleanup code (C code) in at least some of the + * cases could be done within the assembler block. + * x [DONE] the "v3 v2 v1 v0 v7 v6 v5 v4" comments are confusing, + * inconsistent, and don't match the MMX Programmer's Reference + * Manual conventions anyway. They should be changed to + * "b7 b6 b5 b4 b3 b2 b1 b0," where b0 indicates the byte that + * was lowest in memory (e.g., corresponding to a left pixel) + * and b7 is the byte that was highest (e.g., a right pixel). + * + * 19991016: + * - Brennan's Guide notwithstanding, gcc under Linux does *not* + * want globals prefixed by underscores when referencing them-- + * i.e., if the variable is const4, then refer to it as const4, + * not _const4. This seems to be a djgpp-specific requirement. + * Also, such variables apparently *must* be declared outside + * of functions; neither static nor automatic variables work if + * defined within the scope of a single function, but both + * static and truly global (multi-module) variables work fine. + * + * 19991023: + * - fixed png_combine_row() non-MMX replication bug (odd passes only?) + * - switched from string-concatenation-with-macros to cleaner method of + * renaming global variables for djgpp--i.e., always use prefixes in + * inlined assembler code (== strings) and conditionally rename the + * variables, not the other way around. Hence _const4, _mask8_0, etc. + * + * 19991024: + * - fixed mmxsupport()/png_do_read_interlace() first-row bug + * This one was severely weird: even though mmxsupport() doesn't touch + * ebx (where "row" pointer was stored), it nevertheless managed to zero + * the register (even in static/non-fPIC code--see below), which in turn + * caused png_do_read_interlace() to return prematurely on the first row of + * interlaced images (i.e., without expanding the interlaced pixels). + * Inspection of the generated assembly code didn't turn up any clues, + * although it did point at a minor optimization (i.e., get rid of + * mmx_supported_local variable and just use eax). Possibly the CPUID + * instruction is more destructive than it looks? (Not yet checked.) + * - "info gcc" was next to useless, so compared fPIC and non-fPIC assembly + * listings... Apparently register spillage has to do with ebx, since + * it's used to index the global offset table. Commenting it out of the + * input-reg lists in png_combine_row() eliminated compiler barfage, so + * ifdef'd with __PIC__ macro: if defined, use a global for unmask + * + * 19991107: + * - verified CPUID clobberage: 12-char string constant ("GenuineIntel", + * "AuthenticAMD", etc.) placed in ebx:ecx:edx. Still need to polish. + * + * 19991120: + * - made "diff" variable (now "_dif") global to simplify conversion of + * filtering routines (running out of regs, sigh). "diff" is still used + * in interlacing routines, however. + * - fixed up both versions of mmxsupport() (ORIG_THAT_USED_TO_CLOBBER_EBX + * macro determines which is used); original not yet tested. + * + * 20000213: + * - when compiling with gcc, be sure to use -fomit-frame-pointer + * + * 20000319: + * - fixed a register-name typo in png_do_read_interlace(), default (MMX) case, + * pass == 4 or 5, that caused visible corruption of interlaced images + * + * 20000623: + * - Various problems were reported with gcc 2.95.2 in the Cygwin environment, + * many of the form "forbidden register 0 (ax) was spilled for class AREG." + * This is explained at http://gcc.gnu.org/fom_serv/cache/23.html, and + * Chuck Wilson supplied a patch involving dummy output registers.

ALGORITHM + * + * The "deflation" process depends on being able to identify portions + * of the input text which are identical to earlier input (within a + * sliding window trailing behind the input currently being processed). + * + * The most straightforward technique turns out to be the fastest for + * most input files: try all possible matches and select the longest. + * The key feature of this algorithm is that insertions into the string + * dictionary are very simple and thus fast, and deletions are avoided + * completely. Insertions are performed at each input character, whereas + * string matches are performed only when the previous match ends. So it + * is preferable to spend more time in matches to allow very fast string + * insertions and avoid deletions. The matching algorithm for small + * strings is inspired from that of Rabin & Karp. A brute force approach + * is used to find longer strings when a small match has been found. + * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze + * (by Leonid Broukhis). + * A previous version of this file used a more sophisticated algorithm + * (by Fiala and Greene) which is guaranteed to run in linear amortized + * time, but has a larger average cost, uses more memory and is patented. + * However the F&G algorithm may be faster for some highly redundant + * files if the parameter max_chain_length (described below) is too large. + * + * ACKNOWLEDGEMENTS + * + * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and + * I found it in 'freeze' written by Leonid Broukhis. + * Thanks to many people for bug reports and testing. + * + * REFERENCES + * + * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification". + * Available in http://www.ietf.org/rfc/rfc1951.txt + * + * A description of the Rabin and Karp algorithm is given in the book + * "Algorithms" by R.

The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available.

When doing a raw inflate, inflate() + will go ahead and process the first block, and will return when it gets to + the end of that block, or when it runs out of data. + + The Z_BLOCK option assists in appending to or combining deflate streams. + Also to assist in this, on return inflate() will set strm->data_type to the + number of unused bits in the last byte taken from strm->next_in, plus 64 + if inflate() is currently decoding the last block in the deflate stream, + plus 128 if inflate() returned immediately after decoding an end-of-block + code or decoding the complete header up to just before the first byte of the + deflate stream. The end-of-block will not be indicated until all of the + uncompressed data from that block has been written to strm->next_out. The + number of unused bits may in general be greater than seven, except when + bit 7 of data_type is set, in which case the number of unused bits will be + less than eight. + + inflate() should normally be called until it returns Z_STREAM_END or an + error. However if all decompression is to be performed in a single step + (a single call of inflate), the parameter flush should be set to + Z_FINISH. In this case all pending input is processed and all pending + output is flushed; avail_out must be large enough to hold all the + uncompressed data. (The size of the uncompressed data may have been saved + by the compressor for this purpose.) The next operation on this stream must + be inflateEnd to deallocate the decompression state. The use of Z_FINISH + is never required, but can be used to inform inflate that a faster approach + may be used for the single inflate() call. + + In this implementation, inflate() always flushes as much output as + possible to the output buffer, and always uses the faster approach on the + first call. So the only effect of the flush parameter in this implementation + is on the return value of inflate(), as noted below, or when it returns early + because Z_BLOCK is used. + + If a preset dictionary is needed after this call (see inflateSetDictionary + below), inflate sets strm->adler to the adler32 checksum of the dictionary + chosen by the compressor and returns Z_NEED_DICT; otherwise it sets + strm->adler to the adler32 checksum of all output produced so far (that is, + total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described + below. At the end of the stream, inflate() checks that its computed adler32 + checksum is equal to that saved by the compressor and returns Z_STREAM_END + only if the checksum is correct. + + inflate() will decompress and check either zlib-wrapped or gzip-wrapped + deflate data.
