| 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 |
