Fixed bug #80
Date: 21 Apr 2003 17:20:20 +0100
From: Alan Swanson <swanson@uklinux.net>
Subject: [SDL] New XFree 4.3 Video Mode Patch
If you look at the unsorted list of modes returned by X, here's mine;
1280 x 1024 @ 85.0 >
1024 x 768 @ 100.3 > USER
800 x 600 @ 125.5 > SET
640 x 480 @ 124.9 >
1280 x 1024 @ 75.0 ]
1280 x 1024 @ 60.0 ]
1280 x 960 @ 85.0 ] X11
1280 x 960 @ 60.0 ] AUTO
1152 x 864 @ 75.0 ]=20
1152 x 768 @ 54.8 ]
960 x 720 @ 120.0 ]
...
640 x 400 @ 85.1 ] 256k
576 x 432 @ 150.0 ] 249k PIXEL
640 x 350 @ 85.1 ] 224k COUNT
576 x 384 @ 109.6 ] 221k
...
The user set modes come first followed by X set modes which are ordered
by decreasing number of pixels and refresh.
The reason why every other library or program not using SDL working is
due to SDL scanning the modes in reverse getting X11 provided modes
modes with the lowest refresh.

0 | 41 1.2.0: |
42 Added SDL_VIDEOEXPOSE event to signal that the screen needs to | |
43 be redrawn. This is currently only delivered to OpenGL windows | |
44 on X11, though it may be delivered in the future when the video | |
45 memory is lost under DirectX. | |
46 | |
47 1.1.8: | |
48 You can pass SDL_NOFRAME to SDL_VideoMode() to create a window | |
49 that has no title bar or frame decoration. Fullscreen video | |
50 modes automatically have this flag set. | |
51 | |
52 Added a function to query the clipping rectangle for a surface: | |
53 void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
54 | |
55 Added a function to query the current event filter: | |
56 SDL_EventFilter SDL_GetEventFilter(void) | |
57 | |
58 If you pass -1 to SDL_ShowCursor(), it won't change the current | |
59 cursor visibility state, but will still return it. | |
60 | |
61 SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning | |
62 you can nest them as deep as you want, as long as each lock call | |
63 has a matching unlock call. The surface remains locked until the | |
64 last matching unlock call. | |
65 | |
66 Note that you may not blit to or from a locked surface. | |
67 | |
68 1.1.7: | |
69 The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take | |
70 arrays of Uint16 values instead of Uint8 values. For the most part, | |
71 you can just take your old values and shift them up 8 bits to get | |
72 new correct values for your gamma ramps. | |
73 | |
74 You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface() | |
75 and SDL will try to RLE accelerate colorkey and alpha blits in the | |
76 resulting surface. | |
77 | |
78 1.1.6: | |
79 Added a function to return the thread ID of a specific thread: | |
80 Uint32 SDL_GetThreadID(SDL_Thread *thread) | |
81 If 'thread' is NULL, this function returns the id for this thread. | |
82 | |
83 1.1.5: | |
84 The YUV overlay structure has been changed to use an array of | |
85 pitches and pixels representing the planes of a YUV image, to | |
86 better enable hardware acceleration. The YV12 and IYUV formats | |
87 each have three planes, corresponding to the Y, U, and V portions | |
88 of the image, while packed pixel YUV formats just have one plane. | |
89 | |
90 For palettized mode (8bpp), the screen colormap is now split in | |
91 a physical and a logical palette. The physical palette determines | |
92 what colours the screen pixels will get when displayed, and the | |
93 logical palette controls the mapping from blits to/from the screen. | |
94 A new function, SDL_SetPalette() has been added to change | |
95 logical and physical palettes separately. SDL_SetColors() works | |
96 just as before, and is equivalent to calling SDL_SetPalette() with | |
97 a flag argument of (SDL_LOGPAL|SDL_PHYSPAL). | |
98 | |
99 SDL_BlitSurface() no longer modifies the source rectangle, only the | |
100 destination rectangle. The width/height members of the destination | |
101 rectangle are ignored, only the position is used. | |
102 | |
103 The old source clipping function SDL_SetClipping() has been replaced | |
104 with a more useful function to set the destination clipping rectangle: | |
105 SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect) | |
106 | |
107 Added a function to see what subsystems have been initialized: | |
108 Uint32 SDL_WasInit(Uint32 flags) | |
109 | |
110 The Big Alpha Flip: SDL now treats alpha as opacity like everybody | |
111 else, and not as transparency: | |
112 | |
113 A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255 | |
114 A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0 | |
115 Values between 0 and 255 vary from fully transparent to fully opaque. | |
116 | |
117 New functions: | |
118 SDL_DisplayFormatAlpha() | |
119 Returns a surface converted to a format with alpha-channel | |
120 that can be blit efficiently to the screen. (In other words, | |
121 like SDL_DisplayFormat() but the resulting surface has | |
122 an alpha channel.) This is useful for surfaces with alpha. | |
123 SDL_MapRGBA() | |
124 Works as SDL_MapRGB() but takes an additional alpha parameter. | |
125 SDL_GetRGBA() | |
126 Works as SDL_GetRGB() but also returns the alpha value | |
127 (SDL_ALPHA_OPAQUE for formats without an alpha channel) | |
128 | |
129 Both SDL_GetRGB() and SDL_GetRGBA() now always return values in | |
130 the [0..255] interval. Previously, SDL_GetRGB() would return | |
131 (0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format. | |
132 (N.B.: This is broken for bit fields < 3 bits.) | |
133 | |
134 SDL_MapRGB() returns pixels in which the alpha channel is set opaque. | |
135 | |
136 SDL_SetAlpha() can now be used for both setting the per-surface | |
137 alpha, using the new way of thinking of alpha, and also to enable | |
138 and disable per-pixel alpha blending for surfaces with an alpha | |
139 channel: | |
140 To disable alpha blending: | |
141 SDL_SetAlpha(surface, 0, 0); | |
142 To re-enable alpha blending: | |
143 SDL_SetAlpha(surface, SDL_SRCALPHA, 0); | |
144 Surfaces with an alpha channel have blending enabled by default. | |
145 | |
146 SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests | |
147 RLE acceleration of blits, just as like with SDL_SetColorKey(). | |
148 This flag can be set for both surfaces with an alpha channel | |
149 and surfaces with an alpha value set by SDL_SetAlpha(). | |
150 As always, RLE surfaces must be locked before pixel access is | |
151 allowed, and unlocked before any other SDL operations are done | |
152 on it. | |
153 | |
154 The blit semantics for surfaces with and without alpha and colorkey | |
155 have now been defined: | |
156 | |
157 RGBA->RGB: | |
158 SDL_SRCALPHA set: | |
159 alpha-blend (using alpha-channel). | |
160 SDL_SRCCOLORKEY ignored. | |
161 SDL_SRCALPHA not set: | |
162 copy RGB. | |
163 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
164 RGB values of the source colour key, ignoring alpha in the | |
165 comparison. | |
166 | |
167 RGB->RGBA: | |
168 SDL_SRCALPHA set: | |
169 alpha-blend (using the source per-surface alpha value); | |
170 set destination alpha to opaque. | |
171 SDL_SRCALPHA not set: | |
172 copy RGB, set destination alpha to opaque. | |
173 both: | |
174 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
175 source colour key. | |
176 | |
177 RGBA->RGBA: | |
178 SDL_SRCALPHA set: | |
179 alpha-blend (using the source alpha channel) the RGB values; | |
180 leave destination alpha untouched. [Note: is this correct?] | |
181 SDL_SRCCOLORKEY ignored. | |
182 SDL_SRCALPHA not set: | |
183 copy all of RGBA to the destination. | |
184 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
185 RGB values of the source colour key, ignoring alpha in the | |
186 comparison. | |
187 | |
188 RGB->RGB: | |
189 SDL_SRCALPHA set: | |
190 alpha-blend (using the source per-surface alpha value). | |
191 SDL_SRCALPHA not set: | |
192 copy RGB. | |
193 both: | |
194 if SDL_SRCCOLORKEY set, only copy the pixels matching the | |
195 source colour key. | |
196 | |
197 As a special case, blits from surfaces with per-surface alpha | |
198 value of 128 (50% transparency) are optimised and much faster | |
199 than other alpha values. This does not apply to surfaces with | |
200 alpha channels (per-pixel alpha). | |
201 | |
202 New functions for manipulating the gamma of the display have | |
203 been added: | |
204 int SDL_SetGamma(float red, float green, float blue); | |
205 int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
206 int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue); | |
207 Gamma ramps are tables with 256 entries which map the screen color | |
208 components into actually displayed colors. For an example of | |
209 implementing gamma correction and gamma fades, see test/testgamma.c | |
210 Gamma control is not supported on all hardware. | |
211 | |
212 1.1.4: | |
213 The size of the SDL_CDtrack structure changed from 8 to 12 bytes | |
214 as the size of the length member was extended to 32 bits. | |
215 | |
216 You can now use SDL for 2D blitting with a GL mode by passing the | |
217 SDL_OPENGLBLIT flag to SDL_SetVideoMode(). You can specify 16 or | |
218 32 bpp, and the data in the framebuffer is put into the GL scene | |
219 when you call SDL_UpdateRects(), and the scene will be visible | |
220 when you call SDL_GL_SwapBuffers(). | |
221 | |
222 Run the "testgl" test program with the -logo command line option | |
223 to see an example of this blending of 2D and 3D in SDL. | |
224 | |
225 1.1.3: | |
226 Added SDL_FreeRW() to the API, to complement SDL_AllocRW() | |
227 | |
228 Added resizable window support - just add SDL_RESIZABLE to the | |
229 SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events. | |
230 See SDL_events.h for details on the new SDL_ResizeEvent structure. | |
231 | |
232 Added condition variable support, based on mutexes and semaphores. | |
233 SDL_CreateCond() | |
234 SDL_DestroyCond() | |
235 SDL_CondSignal() | |
236 SDL_CondBroadcast() | |
237 SDL_CondWait() | |
238 SDL_CondTimedWait() | |
239 The new function prototypes are in SDL_mutex.h | |
240 | |
241 Added counting semaphore support, based on the mutex primitive. | |
242 SDL_CreateSemaphore() | |
243 SDL_DestroySemaphore() | |
244 SDL_SemWait() | |
245 SDL_SemTryWait() | |
246 SDL_SemWaitTimeout() | |
247 SDL_SemPost() | |
248 SDL_SemValue() | |
249 The new function prototypes are in SDL_mutex.h | |
250 | |
251 Added support for asynchronous blitting. To take advantage of this, | |
252 you must set the SDL_ASYNCBLIT flag when setting the video mode and | |
253 creating surfaces that you want accelerated in this way. You must | |
254 lock surfaces that have this flag set, and the lock will block until | |
255 any queued blits have completed. | |
256 | |
257 Added YUV video overlay support. | |
258 The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU. | |
259 This function creates an overlay surface: | |
260 SDL_CreateYUVOverlay() | |
261 You must lock and unlock the overlay to get access to the data: | |
262 SDL_LockYUVOverlay() SDL_UnlockYUVOverlay() | |
263 You can then display the overlay: | |
264 SDL_DisplayYUVOverlay() | |
265 You must free the overlay when you are done using it: | |
266 SDL_FreeYUVOverlay() | |
267 See SDL_video.h for the full function prototypes. | |
268 | |
269 The joystick hat position constants have been changed: | |
270 Old constant New constant | |
271 ------------ ------------ | |
272 0 SDL_HAT_CENTERED | |
273 1 SDL_HAT_UP | |
274 2 SDL_HAT_RIGHTUP | |
275 3 SDL_HAT_RIGHT | |
276 4 SDL_HAT_RIGHTDOWN | |
277 5 SDL_HAT_DOWN | |
278 6 SDL_HAT_LEFTDOWN | |
279 7 SDL_HAT_LEFT | |
280 8 SDL_HAT_LEFTUP | |
281 The new constants are bitmasks, so you can check for the | |
282 individual axes like this: | |
283 if ( hat_position & SDL_HAT_UP ) { | |
284 } | |
285 and you'll catch left-up, up, and right-up. | |
286 | |
287 1.1.2: | |
288 Added multiple timer support: | |
289 SDL_AddTimer() and SDL_RemoveTimer() | |
290 | |
291 SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL. | |
292 | |
293 1.1.0: | |
294 Added initial OpenGL support. | |
295 First set GL attributes (such as RGB depth, alpha depth, etc.) | |
296 SDL_GL_SetAttribute() | |
297 Then call SDL_SetVideoMode() with the SDL_OPENGL flag. | |
298 Perform all of your normal GL drawing. | |
299 Finally swap the buffers with the new SDL function: | |
300 SDL_GL_SwapBuffers() | |
301 See the new 'testgl' test program for an example of using GL with SDL. | |
302 | |
303 You can load GL extension functions by using the function: | |
304 SDL_GL_LoadProcAddress() | |
305 | |
306 Added functions to initialize and cleanup specific SDL subsystems: | |
307 SDL_InitSubSystem() and SDL_QuitSubSystem() | |
308 | |
309 Added user-defined event type: | |
310 typedef struct { | |
311 Uint8 type; | |
312 int code; | |
313 void *data1; | |
314 void *data2; | |
315 } SDL_UserEvent; | |
316 This structure is in the "user" member of an SDL_Event. | |
317 | |
318 Added a function to push events into the event queue: | |
319 SDL_PushEvent() | |
320 | |
321 Example of using the new SDL user-defined events: | |
322 { | |
323 SDL_Event event; | |
324 | |
325 event.type = SDL_USEREVENT; | |
326 event.user.code = my_event_code; | |
327 event.user.data1 = significant_data; | |
328 event.user.data2 = 0; | |
329 SDL_PushEvent(&event); | |
330 } | |
331 | |
332 Added a function to get mouse deltas since last query: | |
333 SDL_GetRelativeMouseState() | |
334 | |
335 Added a boolean datatype to SDL_types.h: | |
336 SDL_bool = { SDL_TRUE, SDL_FALSE } | |
337 | |
338 Added a function to get the current audio status: | |
339 SDL_GetAudioState(); | |
340 It returns one of: | |
341 SDL_AUDIO_STOPPED, | |
342 SDL_AUDIO_PLAYING, | |
343 SDL_AUDIO_PAUSED | |
344 | |
345 Added an AAlib driver (ASCII Art) - by Stephane Peter. | |
346 | |
347 1.0.6: | |
348 The input grab state is reset after each call to SDL_SetVideoMode(). | |
349 The input is grabbed by default in fullscreen mode, and ungrabbed in | |
350 windowed mode. If you want to set input grab to a particular value, | |
351 you should set it after each call to SDL_SetVideoMode(). | |
352 | |
353 1.0.5: | |
354 Exposed SDL_AudioInit(), SDL_VideoInit() | |
355 Added SDL_AudioDriverName() and SDL_VideoDriverName() | |
356 | |
357 Added new window manager function: | |
358 SDL_WM_ToggleFullScreen() | |
359 This is currently implemented only on Linux | |
360 | |
361 The ALT-ENTER code has been removed - it's not appropriate for a | |
362 lib to bind keys when they aren't even emergency escape sequences. | |
363 | |
364 ALT-ENTER functionality can be implemented with the following code: | |
365 | |
366 int Handle_AltEnter(const SDL_Event *event) | |
367 { | |
368 if ( event->type == SDL_KEYDOWN ) { | |
369 if ( (event->key.keysym.sym == SDLK_RETURN) && | |
370 (event->key.keysym.mod & KMOD_ALT) ) { | |
371 SDL_WM_ToggleFullScreen(SDL_GetVideoSurface()); | |
372 return(0); | |
373 } | |
374 } | |
375 return(1); | |
376 } | |
377 SDL_SetEventFilter(Handle_AltEnter); | |
378 | |
379 1.0.3: | |
380 Under X11, if you grab the input and hide the mouse cursor, | |
381 the mouse will go into a "relative motion" mode where you | |
382 will always get relative motion events no matter how far in | |
383 each direction you move the mouse - relative motion is not | |
384 bounded by the edges of the window (though the absolute values | |
385 of the mouse positions are clamped by the size of the window). | |
386 The SVGAlib, framebuffer console, and DirectInput drivers all | |
387 have this behavior naturally, and the GDI and BWindow drivers | |
388 never go into "relative motion" mode. | |
389 | |
390 1.0.2: | |
391 Added a function to enable keyboard repeat: | |
392 SDL_EnableKeyRepeat() | |
393 | |
394 Added a function to grab the mouse and keyboard input | |
395 SDL_WM_GrabInput() | |
396 | |
397 Added a function to iconify the window. | |
398 SDL_WM_IconifyWindow() | |
399 If this function succeeds, the application will receive an event | |
400 signaling SDL_APPACTIVE event | |
401 | |
402 1.0.1: | |
403 Added constants to SDL_audio.h for 16-bit native byte ordering: | |
404 AUDIO_U16SYS, AUDIO_S16SYS | |
405 | |
406 1.0.0: | |
407 New public release | |
408 | |
409 Version 0.11: | |
410 | |
411 0.11.5: | |
412 A new function SDL_GetVideoSurface() has been added, and returns | |
413 a pointer to the current display surface. | |
414 | |
415 SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and | |
416 a new function SDL_CreateRGBSurfaceFrom() has been added to allow | |
417 creating an SDL surface from an existing pixel data buffer. | |
418 | |
419 Added SDL_GetRGB() to the headers and documentation. | |
420 | |
421 0.11.4: | |
422 SDL_SetLibraryPath() is no longer meaningful, and has been removed. | |
423 | |
424 0.11.3: | |
425 A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from | |
426 installing fatal signal handlers on operating systems that support | |
427 them. | |
428 | |
429 Version 0.9: | |
430 | |
431 0.9.15: | |
432 SDL_CreateColorCursor() has been removed. Color cursors should | |
433 be implemented as sprites, blitted by the application when the | |
434 cursor moves. To get smooth color cursor updates when the app | |
435 is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init(). This | |
436 allows you to handle the mouse motion in another thread from an | |
437 event filter function, but is currently only supported by Linux | |
438 and BeOS. Note that you'll have to protect the display surface | |
439 from multi-threaded access by using mutexes if you do this. | |
440 | |
441 Thread-safe surface support has been removed from SDL. | |
442 This makes blitting somewhat faster, by removing SDL_MiddleBlit(). | |
443 Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead. | |
444 You can make your surfaces thread-safe by allocating your own | |
445 mutex and making lock/unlock calls around accesses to your surface. | |
446 | |
447 0.9.14: | |
448 SDL_GetMouseState() now takes pointers to int rather than Uint16. | |
449 | |
450 If you set the SDL_WINDOWID environment variable under UNIX X11, | |
451 SDL will use that as the main window instead of creating it's own. | |
452 This is an unsupported extension to SDL, and not portable at all. | |
453 | |
454 0.9.13: | |
455 Added a function SDL_SetLibraryPath() which can be used to specify | |
456 the directory containing the SDL dynamic libraries. This is useful | |
457 for commercial applications which ship with particular versions | |
458 of the libraries, and for security on multi-user systems. | |
459 If this function is not used, the default system directories are | |
460 searched using the native dynamic object loading mechanism. | |
461 | |
462 In order to support C linkage under Visual C++, you must declare | |
463 main() without any return type: | |
464 main(int argc, char *argv[]) { | |
465 /* Do the program... */ | |
466 return(0); | |
467 } | |
468 C++ programs should also return a value if compiled under VC++. | |
469 | |
470 The blit_endian member of the SDL_VideoInfo struct has been removed. | |
471 | |
472 SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there | |
473 is now no longer any function to translate a keysym to a character. | |
474 | |
475 The SDL_keysym structure has been extended with a 'scancode' and | |
476 'unicode' member. The 'scancode' is a hardware specific scancode | |
477 for the key that was pressed, and may be 0. The 'unicode' member | |
478 is a 16-bit UNICODE translation of the key that was pressed along | |
479 with any modifiers or compose keys that have been pressed. | |
480 If no UNICODE translation exists for the key, 'unicode' will be 0. | |
481 | |
482 Added a function SDL_EnableUNICODE() to enable/disable UNICODE | |
483 translation of character keypresses. Translation defaults off. | |
484 | |
485 To convert existing code to use the new API, change code which | |
486 uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(), | |
487 and change code which uses it to get the ASCII value of a sym to | |
488 use the 'unicode' member of the event keysym. | |
489 | |
490 0.9.12: | |
491 There is partial support for 64-bit datatypes. I don't recommend | |
492 you use this if you have a choice, because 64-bit datatypes are not | |
493 supported on many platforms. On platforms for which it is supported, | |
494 the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and | |
495 you can use the Uint64 and Sint64 datatypes. | |
496 | |
497 Added functions to SDL_endian.h to support 64-bit datatypes: | |
498 SDL_SwapLE64(), SDL_SwapBE64(), | |
499 SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64() | |
500 | |
501 A new member "len_ratio" has been added to the SDL_AudioCVT structure, | |
502 and allows you to determine either the original buffer length or the | |
503 converted buffer length, given the other. | |
504 | |
505 A new function SDL_FreeWAV() has been added to the API to free data | |
506 allocated by SDL_LoadWAV_RW(). This is necessary under Win32 since | |
507 the gcc compiled DLL uses a different heap than VC++ compiled apps. | |
508 | |
509 SDL now has initial support for international keyboards using the | |
510 Latin character set. | |
511 If a particular mapping is desired, you can set the DEFAULT_KEYBOARD | |
512 compile-time variable, or you can set the environment variable | |
513 "SDL_KEYBOARD" to a string identifying the keyboard mapping you desire. | |
514 The valid values for these variables can be found in SDL_keyboard.c | |
515 | |
516 Full support for German and French keyboards under X11 is implemented. | |
517 | |
518 0.9.11: | |
519 The THREADED_EVENTS compile-time define has been replaced with the | |
520 SDL_INIT_EVENTTHREAD flag. If this flag is passed to SDL_Init(), | |
521 SDL will create a separate thread to perform input event handling. | |
522 If this flag is passed to SDL_Init(), and the OS doesn't support | |
523 event handling in a separate thread, SDL_Init() will fail. | |
524 Be sure to add calls to SDL_Delay() in your main thread to allow | |
525 the OS to schedule your event thread, or it may starve, leading | |
526 to slow event delivery and/or dropped events. | |
527 Currently MacOS and Win32 do not support this flag, while BeOS | |
528 and Linux do support it. I recommend that your application only | |
529 use this flag if absolutely necessary. | |
530 | |
531 The SDL thread function passed to SDL_CreateThread() now returns a | |
532 status. This status can be retrieved by passing a non-NULL pointer | |
533 as the 'status' argument to SDL_WaitThread(). | |
534 | |
535 The volume parameter to SDL_MixAudio() has been increased in range | |
536 from (0-8) to (0-128) | |
537 | |
538 SDL now has a data source abstraction which can encompass a file, | |
539 an area of memory, or any custom object you can envision. It uses | |
540 these abstractions, SDL_RWops, in the endian read/write functions, | |
541 and the built-in WAV and BMP file loaders. This means you can load | |
542 WAV chunks from memory mapped files, compressed archives, network | |
543 pipes, or anything else that has a data read abstraction. | |
544 | |
545 There are three built-in data source abstractions: | |
546 SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem() | |
547 along with a generic data source allocation function: | |
548 SDL_AllocRW() | |
549 These data sources can be used like stdio file pointers with the | |
550 following convenience functions: | |
551 SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose() | |
552 These functions are defined in the new header file "SDL_rwops.h" | |
553 | |
554 The endian swapping functions have been turned into macros for speed | |
555 and SDL_CalculateEndian() has been removed. SDL_endian.h now defines | |
556 SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on | |
557 the endianness of the host system. | |
558 | |
559 The endian read/write functions now take an SDL_RWops pointer | |
560 instead of a stdio FILE pointer, to support the new data source | |
561 abstraction. | |
562 | |
563 The SDL_*LoadWAV() functions have been replaced with a single | |
564 SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's | |
565 first parameter, and a flag whether or not to automatically | |
566 free it as the second parameter. SDL_LoadWAV() is a macro for | |
567 backward compatibility and convenience: | |
568 SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...); | |
569 | |
570 The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced | |
571 with a single function that takes a SDL_RWops pointer as it's | |
572 first parameter, and a flag whether or not to automatically | |
573 free it as the second parameter. SDL_LoadBMP() and SDL_SaveBMP() | |
574 are macros for backward compatibility and convenience: | |
575 SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...); | |
576 SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...); | |
577 Note that these functions use SDL_RWseek() extensively, and should | |
578 not be used on pipes or other non-seekable data sources. | |
579 | |
580 0.9.10: | |
581 The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been | |
582 extended to support multiple types of display drivers, as well as | |
583 safe access to the X11 display when THREADED_EVENTS is enabled. | |
584 The new structures are documented in the SDL_syswm.h header file. | |
585 | |
586 Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard | |
587 should now work properly, as well as the "Windows" keys on US | |
588 keyboards. | |
589 | |
590 The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab | |
591 instead of trying to open each block device on the system. | |
592 The CD must be listed in /etc/fstab as using the iso9660 filesystem. | |
593 | |
594 On Linux, if you define THREADED_EVENTS at compile time, a separate | |
595 thread will be spawned to gather X events asynchronously from the | |
596 graphics updates. This hasn't been extensively tested, but it does | |
597 provide a means of handling keyboard and mouse input in a separate | |
598 thread from the graphics thread. (This is now enabled by default.) | |
599 | |
600 A special access function SDL_PeepEvents() allows you to manipulate | |
601 the event queue in a thread-safe manner, including peeking at events, | |
602 removing events of a specified type, and adding new events of arbitrary | |
603 type to the queue (use the new 'user' member of the SDL_Event type). | |
604 | |
605 If you use SDL_PeepEvents() to gather events, then the main graphics | |
606 thread needs to call SDL_PumpEvents() periodically to drive the event | |
607 loop and generate input events. This is not necessary if SDL has been | |
608 compiled with THREADED_EVENTS defined, but doesn't hurt. | |
609 | |
610 A new function SDL_ThreadID() returns the identifier associated with | |
611 the current thread. | |
612 | |
613 0.9.9: | |
614 The AUDIO_STEREO format flag has been replaced with a new 'channels' | |
615 member of the SDL_AudioSpec structure. The channels are 1 for mono | |
616 audio, and 2 for stereo audio. In the future more channels may be | |
617 supported for 3D surround sound. | |
618 | |
619 The SDL_MixAudio() function now takes an additional volume parameter, | |
620 which should be set to SDL_MIX_MAXVOLUME for compatibility with the | |
621 original function. | |
622 | |
623 The CD-ROM functions which take a 'cdrom' parameter can now be | |
624 passed NULL, and will act on the last successfully opened CD-ROM. | |
625 | |
626 0.9.8: | |
627 No changes, bugfixes only. | |
628 | |
629 0.9.7: | |
630 No changes, bugfixes only. | |
631 | |
632 0.9.6: | |
633 Added a fast rectangle fill function: SDL_FillRect() | |
634 | |
635 Addition of a useful function for getting info on the video hardware: | |
636 const SDL_VideoInfo *SDL_GetVideoInfo(void) | |
637 This function replaces SDL_GetDisplayFormat(). | |
638 | |
639 Initial support for double-buffering: | |
640 Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode() | |
641 Update the screen with a new function: SDL_Flip() | |
642 | |
643 SDL_AllocSurface() takes two new flags: | |
644 SDL_SRCCOLORKEY means that the surface will be used for colorkey blits | |
645 and if the hardware supports hardware acceleration of colorkey blits | |
646 between two surfaces in video memory, to place the surface in video | |
647 memory if possible, otherwise it will be placed in system memory. | |
648 SDL_SRCALPHA means that the surface will be used for alpha blits and | |
649 if the hardware supports hardware acceleration of alpha blits between | |
650 two surfaces in video memory, to place the surface in video memory | |
651 if possible, otherwise it will be placed in system memory. | |
652 SDL_HWSURFACE now means that the surface will be created with the | |
653 same format as the display surface, since having surfaces in video | |
654 memory is only useful for fast blitting to the screen, and you can't | |
655 blit surfaces with different surface formats in video memory. | |
656 | |
657 0.9.5: | |
658 You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume | |
659 that the icon consists of the entire image. | |
660 | |
661 SDL_LowerBlit() is back -- but don't use it on the display surface. | |
662 It is exactly the same as SDL_MiddleBlit(), but doesn't check for | |
663 thread safety. | |
664 | |
665 Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take | |
666 a FILE pointer instead of a file name. | |
667 | |
668 Added CD-ROM audio control API: | |
669 SDL_CDNumDrives() | |
670 SDL_CDName() | |
671 SDL_CDOpen() | |
672 SDL_CDStatus() | |
673 SDL_CDPlayTracks() | |
674 SDL_CDPlay() | |
675 SDL_CDPause() | |
676 SDL_CDResume() | |
677 SDL_CDStop() | |
678 SDL_CDEject() | |
679 SDL_CDClose() | |
680 | |
681 0.9.4: | |
682 No changes, bugfixes only. | |
683 | |
684 0.9.3: | |
685 Mouse motion event now includes relative motion information: | |
686 Sint16 event->motion.xrel, Sint16 event->motion.yrel | |
687 | |
688 X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT | |
689 (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile) | |
690 | |
691 0.9.2: | |
692 No changes, bugfixes only. | |
693 | |
694 0.9.1: | |
695 Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now | |
696 automatically mapped on blit. | |
697 | |
698 0.8.0: | |
699 SDL stable release |
